Koen Olthuis has been touting the benefits of floating cities for years – and now people are starting to take notice

A number of high-profile projects have recently brought attention to Koen Olthuis’s approach to living on water. Those include the floating Citadel apartment block in the Netherlands and important large-scale leisure projects such as luxury private islands in Dubai, floating hotels and resorts in the Maldives and a snowflake-shaped hotel off Norway. The potential for floating architecture, Olthuis says, goes far beyond one-off developments: it’s an urban planning tool.
“For the past 15 years, I’ve been designing these floating structures,” says Olthuis, who established his design firm Waterstudio in 2003. “When I started, all the other architects thought I was crazy, but now this approach is starting to be adopted by developers. We’re also talking to governments around the world about how floating developments can upgrade and improve their cities.” The big picture in all this, according to Olthuis, is that extending cities beyond the waterfront and indeed further out to sea reduces the pressure on overpopulated urban areas – where 70 per cent of people will live by 2050 – and offers flexible solutions for problems thrown up by rising sea levels and climate change.

How do floating structures work at a city level?
Governments worldwide are looking at how floating developments can improve their cities. I propose a system of modular floating developments – floating urban components that add a particular function to the existing grid of a city. With this system, any question a city asks can be answered immediately. If a city needs parking, bring in floating parking. If it has green issues, bring in floating parks and Sea Trees [Waterstudio’s offshore green structures]. The system is responsive to the needs of dynamic urban communities.

Is floating architecture the way forward for urban living?
It’s project to product. You’ll be able to order buildings in, and sell or lease buildings you don’t want or need. We’ve only explored a fraction of the possibilities, but in the next 10 to 15 years, more and more architecture will start to explore the possibilities of floating developments and it will grow from something that’s a fringe architecture to something that’s mainstream. The stupid thing is that we live in dynamic communities and yet we build static structures. With rapidly changing social structures and technologies, we need flexible cities. I’m not saying we have to build floating cities, but that every city that is next to the water should have at least 5 per cent of its buildings on the water. That would create flexibility.
It’s not the only way, but it’s something that is inevitable. It’s about rethinking and finding solutions for major problems.

What other advantages are there?
We believe green is good but blue is better. Water provides many tools to make more durable and sustainable cities. You have water cooling for the buildings, you have flexibility, you have buildings that rise and fall with the water level, you don’t have to demolish a building that’s no longer needed because you can repurpose it or even sell it. People, developers and politicians are starting to see that this is something that brings in money and solves problems. It’s a feasible way to build better cities.

What do you mean by flexibility?
I don’t mean that you’ll be able to take your house and move to another city or another neighbourhood. I mean flexibility on a larger scale, where cities and urban planners are able to move a complete neighbourhood half a mile or bring in temporary floating functions – like stadiums – and use them for one or two years before they leave for another city. This large-scale flexibility makes sense. Take the Olympic Games. It’s so strange that every four years we build so many hotels and stadiums and only use them for a few weeks. Imagine if as a city you could just lease these floating functions from a developer. Cities who don’t have as much money as London or Rio or Beijing could also host these types of events because it would cost much less money.

Is it something you can foresee happening in the near future ?
Yes, maybe not with stadiums – because we can put them up easily – but with the hotel business, certainly. Qatar has the World Cup in 2022 and they need 35,000 hotel rooms for that event. But if they built 35,000 hotel rooms, within 10 years they’d be empty. So they’re thinking about using cruise ships. As the harbour facility is not big enough, they’re also thinking about the idea of fl oating harbours, or fl oating cruise terminals – something that can facilitate these cruise ships for a few weeks, and then a: er that you can bring the fl oating harbours to another location.

Can you tell us about Amillarah Private Islands?
Yes. With OQYANA Real Estate Company and developers Dutch Docklands, 33 private islands are being built as part of The World Islands project in Dubai. The islands are being sold by Christie’s International Real Estate, with a starting price of US$10m. It’s a really high-end project. The fl oating islands look like tropical islands covered in trees, but in fact they’re more like superyachts. They’re built in Holland and then moved to the location in Dubai and anchored there. They are self-su5cient with their own electricity and their own water. Within the next 10 years there’ll be more development around them, so we’re making it look like its own archipelago. If you fly over, it looks like a series of green islands. OQYANA has a masterplan around Amillarah that includes shops, hotels and all kinds of leisure architecture. This is just the first step of the development, but the beauty of this floating architecture is that it moves very fast. Once you’ve built the islands you can just tow them in and connect them to the boKom, either with cables or telescopic piles and they’re ready. Compare that to the manmade islands at The World. There’s still very liKle built there. It’s di5cult to get labour there, di5cult to build the right foundations and there’s no electricity or water, so developers don’t know how to build there without losing money.

Have any been sold?
Not yet. We’ll have an island there, like a show home, from December this year (2016). With the history of the property market in Dubai, it’s beKer to have the first islands  there so people can have a look and understand what it’s all about, especially at the prices people pay in this type of market. I should add that if I only ever build floating islands for the rich then I’m doing something wrong. The start of this story for me was to create a new tool for cities that are facing urbanisation, overpopulation and climate change – and also for cities that need to brand themselves to aKract inhabitants. As well as being able to answer these big, fast-changing urban problems, these floating structures bring a certain character and appeal to a city – a USP.

Why does your concept appeal to resort or hotel developers?
On water, leisure architecture, including resorts and hotels, has the possibility to change. You can adapt and create functions that are not only moveable but also transformative through time, for instance, through the seasons. With seasonal structures you can open up the buildings in the summer, make buildings more dense or more spread out. You can add functions or take them away. To me, it’s one big playing field and we’re trying to work out what it means for the future of leisure architecture and real estate, not just how these things will look, but the economic eUects too.

What kind of economic benefits might there be?
A project we started working on a few years ago was a floating hotel and conference centre for the Maldives – the Greenstar. As well as answering fast-changing urban problems, floating structures bring a certain character to a city – a USP The star-shaped hotel has five legs, each with 80 rooms inside, but instead of building five legs, we build six. One of these legs will stay in a harbour in India. In five or seven years time, when the hotel needs refurbishing, you bring the sixth leg to the hotel and connect it, sending the others one by one to be renovated. The hotel doesn’t need to shut down, and the work can be carried out where it’s easy and cost-eBective to get the materials and labour to do it.

What other projects are you working on?
We’re working in the Middle East, in Abu Dhabi, Dubai and Oman, exploring the potential of ecotourism. We’re looking at building satellite resorts for land-sited hotels, that float out at sea where there are coral reefs or mangroves. Floating resorts don’t leave any scars on the environment – they’re scarless developments, which can even have a positive eBect on the environment. For example, we work with marine engineers and environmentalists to help build floating structures that aKract underwater life. In places like Dubai, it’s so hot that it’s very
diLcult to create the right environment for fish and marine life, but the shade of these floating islands can provide a starting point for new marine ecosystems. We’re also working with master developer Dutch Docklands and the Maldivean government on the ongoing Five Lagoons Ocean Flower resort and residences. Finally, we’re looking at developing cities that face troubles with the environment, density and infrastructure – and seeing how water can be part of that solution.

What are the challenges?
Progress on Norway’s Krystall Hotel is slow because of laws that prevent building on the shoreline. Regulations and laws can be a hurdle, and may need to be changed to adapt to floating architecture. But, we are slowly moving to a marketplace where these floating developments are accepted. There’s a bright future for this technology.

Slum Schools
Waterstudio has been pioneering the concept of floating facilities that can be moored at waterside slum communities anywhere in the world. City Apps are floating developments based on a standard sea-freight container. City Apps can be established in water where there is scarcity of space and can be used to upgrade sanitation, housing and communication installations. The first City App, a floating school, is being built for a slum in Dhaka. “One billion people live in slums worldwide and half of them are close to the water. We can use City Apps to instantly improve the quality of life there,” says Olthuis. Because governments see these as temporary solutions, it’s much easier to get permission to do this than to build a facility on land.

A Future Afloat

IT MAY SOUND CRAZY TODAY, BUT DESIGNERS AND ENGINEERS AROUND THE WORLD ARE ALREADY EMBRACING LIFE ON THE WATER

For more than 14 years, Dutch architect Koen Olthuis has been designing buildings that float. His portfolio includes the construction of 200 floating homes and offices in the Netherlands.

Later this year, luxurious floating islands designed by his Rijswijk­based architecture firm, Waterstudio, will be shipped from the Netherlands to Dubai and the Maldives. Olthuis is also experimenting with floating computer classrooms and other facilities called City Apps that he hopes will soon be transported to flood­prone Bangladesh. And he’s in contact with a New Jersey developer who wants to transform the Lincoln Harbor Yacht Marina into a floating residential community with views of the Manhattan skyline.

Olthuis has other ambitious ideas, too. On his architecture firm’s website, www.Waterstudio.nl, you’ll find plans for floating apartment buildings, floating restaurants, floating hotels, floating cruise ship terminals, floating places of worship, floating beaches, floating golf courses, floating “sea trees” for animals, floating facilities (City Apps) for flooded slums, and floating islands for  he very wealthy.

“When we started in 2003, we were the only office that was 100 percent into floating structures,” says Olthuis. “Everybody said we were crazy. But we saw the market, and today there are many, many architects working on floating structures in Holland and in Europe. It has become more mainstream.”

Olthuis also wants to bring his designs to Miami’s urban areas and show that water, especially in the form of rising sea levels, doesn’t have to be an obstacle to future development. It can be an asset.

“The reason I’m an architect is that our cities are not perfect. They don’t function as well as they should,” says Olthuis, who floats his structures on concrete box foundations filled with Styrofoam. “I think that water is the next ingredient to improve the performance of cities.”

Rising seas pose a major threat to Greater Miami. Within the next 80 years, climate change may result in ocean levels that are up to seven feet higher than today, washing out huge sections of flat Florida. But Olthuis feels his floating structures can literally rise to the challenges that tides could bring in the coming decades. And for the present, he argues, floating neighborhoods can provide greater flexibility for urban planners, especially in places like Miami and Manhattan, where vacant land is scarce and expensive.

So far, Miami has not taken well to his plans. His idea to create a floating Major League Soccer stadium for David Beckham in downtown Miami didn’t sail. And his proposal to build a floating parking facility for the American Airlines Arena ran aground.

And then there is Maule Lake, a privately owned body of water in North Miami Beach bordering the upscale neighborhood of Eastern Shores. Business associates of Olthuis, through the Dutch Docklands Company, were contracted to buy the lake. It’s here that Olthuis planned to anchor 29 artificial islands ­­ each about 7000 square feet, with a four­bedroom house, vegetation, swimming pool, and a couple of boat docks ­­ and sell them for $12.5 million apiece. A 30th island, called an “amenity island,” was to feature a clubhouse. The floating community would be called Amillarah. (The project is named after another Dutch Docklands venture, Amillarah, in the Maldives. The word amillarah means private island in Maldivian, according to Dutch Docklands.)

Many Eastern Shores homeowners were horrified at the thought of 30 private islands being built in what they considered their backyard. Among their fears: that the islands would become projectiles during powerful hurricanes, that they would ruin the aesthetics of the neighborhood, and that they would attract throngs of gawkers.

“We don’t want it. We’re going to fight against it. And we’re not going to let it happen,” said Chuck Asarnow, president of the Eastern Shores Homeowners Association, in an interview with the BT in May 2015. In response to the outcry, the North Miami Beach City Council (four members of which, including Mayor George Vallejo, lived in Eastern Shores) declared Maule Lake to be a “conservation area” in July 2015, thus prohibiting development.

But Amillarah in North Miami Beach may not be dead in the water. This past October, Scott Weires, an attorney representing Raymond Gaylord Williams, the owner of Maule Lake, sent North Miami Beach officials a letter announcing his client’s intention to sue under Florida’s Bert J. Harris, Jr. Property Rights Protection Act for $37 million in damages if the city doesn’t rezone the lake. Maule Lake, incidentally, was a rock quarry used by the Maule Rock Mining Company, run by E.L. Maule, in the early 20th century. Williams is a descendant of Maule.

Under the Harris Property Rights Protection Act, a private property owner can seek relief when a governmental body imposes restrictions on the use of that property.

In a February 2, 2017, memo to NMB officials, city attorney José Smith stated that the Williams claim “lacks both merit and validity,” and that the law firm of Weiss Sorota Helfman had been retained to represent the city. Eastern Shores residents remain defiant, insisting that there were never any rights to build on the lake because it was never zoned for development.

“That took them awhile. I thought it was over,” says Fortuna Smukler, chair of the Eastern Shores Crimewatch committee, regarding Williams’s filing of a Harris action 18 months after the city designated the lake a conservation area. “I have confidence in our city attorney. He originally said that Williams won’t have a claim, and I believe him.”

Adds David Templer, an attorney and board member of the Eastern Shores Homeowners Association: “It’s pretty interesting that we use up all the waterfront land [for development] and, hey, now we can use up the water, too.” Weires contends that Williams has the right to develop the lake he has inherited, or to sell it with the development rights attached.

“Our investigation has revealed that these privately owned lands are not environmentally restricted and were never properly zoned by the city,” Weires tells the BT. “As a result, we contend that our client has a constitutional right to develop the entire parcel any way he wishes.

“That said,” Weires continues, “our client has always been, and continues to be, open to discussing possible resolutions with the city that would allow for the reasonable development of some portion of the 117 acres, while maintaining a large amount of the open water.”

And Olthuis? He’s still interested in building floating homes for Maule Lake. It will be a chance to showcase his buoyant residences, designed to withstand the strongest hurricanes, as an environmentally friendly method of developing submerged real estate.

“Miami can test these kinds of floating structures in order to use them on a bigger scale in the near future,” he says.

Olthuis isn’t the only person seeking to build innovative structures directly on the water. There are a number of bold designs floating around.

Among those proposing plans is the California­based Seasteading Institute, a nonprofit organization that received significant early funding from libertarian by Libertarian billionaire Peter Thiel “to provide a machinery of freedom to choose new societies on the blue frontier.” This past January, the Seasteading Institute signed a memorandum of understanding with the French Polynesian government that aims to build the first phase of a selfsustaining, floating village within the territorial waters, which would also have its own Special Economic Zone and “unique governing framework.”

The village, estimated to cost between $10 million and $50 million, is being designed by Blue 21, a Dutch engineering firm that also specializes in building floating structures. It will be  constructed by Blue Frontiers, a for­profit company spun off from the Seasteading Institute. Not to be confused with the nonprofit marine conservation group Blue Frontier Campaign, the Seasteaders’ Blue Frontiers aims “to develop and construct floating islands and to operate the seazone.” The institute envisions thousands of seasteads “across French Polynesia, the Pacific, and the world” that would “test new ideas for government.”

Doug Pope, a Jacksonville­based shipwreck treasure hunter, also wants to jump­start plans to create his project, Oceana Water Resort, a 50­unit hotel sitting on an elevated platform and rising six stories above the Gulf of Mexico, 16 miles northwest of Key West. It would be situated in water 55­60 feet deep, he told the Miami Herald in February, and sit on pilings that could be raised and lowered as needed. Oceana, Pope declares, will be designed to withstand winds up to 200 miles per hour and will be powered by generators in concert with wind and solar power.

And in Riviera Beach in Palm Beach County, Fane Lozman, a former outspoken North Bay Village activist, wants to build state­of­the­art stilt homes capable of responding to the tides, on 25 acres of prime submerged real estate that’s just a few miles from President Donald Trump’s Mar­a­Lago.

Steve Israel, a real estate investor and developer, says Mother Nature inspired his desire to turn Lincoln Harbor Yacht Club in Weehawken, New Jersey, a marina he has owned for 25 years, into a floating­home community.

“Hurricane Sandy flooded everything around us, including things that were anchored on the ground,” Israel recounts. “But all my boats floated up. We have high pilings ­­ and no damage.”

Olthuis has already designed a “double­story flood­resistant yacht” without motors that can serve as floating homes for Lincoln Harbor. But because New Jersey bans stationary houseboats, Israel is also seeking someone who can build luxury “livable yachts” with engines and limited mobility ­­ at least until the houseboat law is overturned.

“This is what I am mostly excited about,” Israel says, touting the marina’s views of Manhattan and
proximity to a New Jersey­New York ferry. Israel sees this as an opportunity to destroy a nationwide stigma against houseboats, and a means to prepare for a wetter future. “Both cities [New York and Miami] are likely to be flooded in the near future,” he says. “Why assume that the places we live have to be anchored to the ground?”

If his Lincoln Harbor venture works out, Israel may try something similar for the marina he’s redeveloping in Fort Myers near the site of a future 18­story condo he may co­develop or sell to another investor. (The proposed condo has parking on the first three floors, Israel says, partly as a precaution against future flooding events.) Israel would also love to set up a floating community in Miami: “I do believe Miami is very ripe for the same kind of deal.”

Building directly on the water isn’t a new thing. There’s Olthuis anticipated a parking crunch with this structure floating next to American Airlines Arena.
evidence that people have lived in stilt­houses on the shores of lakes and seas since prehistoric times. And there have been floating villages in Asia for centuries.

In Florida, the waterways of Miami and Miami Beach were once filled with houseboats, says Paul George, a historian affiliated with the HistoryMiami Museum, and a “It kind of evolved,” George says, noting that the first houseboats on the Miami River, in the 1920s, were anchored near Grove Park in today’s Little Havana. “My sense is that some of these people were Northerners,” he says. “They were staying on houseboats, staying during the season, which is wintertime in Miami.” By the 1930s and 1940s, there were hundreds of houseboats on local waterways.

By the 1950s and 1960s, houseboats were also tied to docks in Miami Beach and North Bay Village, inspiring a television show in the early 1960s called Surfside 6, about a detective agency based on a houseboat moored across the street from Miami Beach’s Fontainebleau Hotel.

Just off of Key Biscayne, in the shallow waters of Biscayne Bay, another aquatic community sprouted, called Stiltsville. Its origins can be traced to 1933, when Crawfish Eddie Walker turned a wrecked ship into a spot where he could sell chowder and bait to recreational fisherman. “He was a great storyteller,” George says.

Within a few years, Walker had neighbors. Various clubs, restaurants, lodges, and weekend homes were established, either on grounded ships or in stilt houses that rose ten feet or more above sea level.

At its height there were 27 houses and converted shipwrecks in Stiltsville. But the community’s structures were gradually weeded out by hurricanes. Prior to Hurricane Betsy in 1965, there were 24 businesses operating on old ships and stilt­houses, notes George. After Betsy there were just 17.

Permits for new structures stopped after Biscayne National Park took over Stiltsville in 1980. The businesses and residences that remained were allowed to operate another two decades. Then along came Hurricane Andrew, which whittled the houses down to seven. After a campaign was launched to save the structures, the remaining seven houses are now shuttered, preserved relics that are maintained by their former owners, now referred to as “caretakers.”

Hurricanes slashed the number of houseboats in Miami and Miami Beach, too. That and a growing stigma toward houseboats. Some of the vessels on the Miami River became unsightly hunks of junk. George says the houseboat dwellers were often referred to as “river rats.” By the 1980s and 1990s, the City of Miami was outlawing them on the Miami River and other waterways. Miami Beach passed similar legislation. And marinas? They started turning away houseboats and other vessels used as full­time residences.

It’s thanks to Fane Lozman that Dutch Docklands now has some added legal support in its pursuit of the Maule Lake project. Lozman, the creator of Scanshift, a software program that keeps tabs on the stock market, fell in love with the Miami houseboat lifestyle more than a decade ago and fought all the way up to the U.S. Supreme Court for his right to continue living on one.

Lozman has a reputation for fighting. In 2003, when his first houseboat was tied up in North Bay Village, he tangled with Al Coletta, a politically influential property owner who allegedly threatened Lozman when he asked if a ramp could be provided for a disabled elderly houseboat owner.

Soon Lozman was fighting Coletta’s allies at North Bay Village City Hall. In November 2003, Commissioner Robert Dugger was arrested for official misconduct based on evidence Lozman collected showing that Dugger failed to disclose his financial connections to Coletta. The Seasteading Institute hopes to build a floating city in French Polynesia, like this concept designed by Blue21.

In April 2004, police Chief David Heller resigned and Mayor Al Dorne and Commissioner Armand Abecassis were arrested for actions related to an obscene threatening cartoon left anonymously in Lozman’s mail.

Lozman might still be in North Bay Village if it hadn’t been for Hurricane Wilma in October 2005. His houseboat survived, but 41 of the neighboring houseboats sank, and the marina where he docked was destroyed. In the aftermath, he discovered that many marinas were reluctant to accept houseboats for fear of turning them into “aquatic trailer parks.”

The only place that would accept Lozman’s houseboat was a marina owned by the City of Riviera Beach, 75 miles up the coast from North Bay Village. Within two months of relocating, Lozman learned that the city planned to condemn the marina as part of a controversial $2.3 billion waterfront redevelopment plan. Lozman sued to stop the project. Riviera Beach officials responded by claiming that Lozman hadn’t paid his dock fees, an accusation he denied. In 2009, after a circuit court judge ruled that his motor­less houseboat was a “vessel,”

Riviera Beach officials seized his houseboat under admiralty law, towed it away, and destroyed it. Lozman, in turn, appealed the case all the way to the U.S. Supreme Court. In 2013, the court ruled that Lozman’s houseboat was, indeed, a home and not a vessel.

Although Lozman says he’s still litigating to be compensated for his home’s destruction, it was his case that has helped Koen Olthuis’s Dutch Docklands associates argue that the proposed floating islands in Maule Lake will be, in fact, floating properties. Lozman bought another houseboat, a circa­1967 two­story home that was once featured in a Frank Sinatra crime drama called Lady in Cement. Unable to find another marina, he kept it anchored in Biscayne Bay near in the 79th Street Causeway.

Then in 2014, he was contacted by the owners of 200 acres of submerged property on the Intracoastal Waterway, along A1A in Singer Island, a narrow strip of land that is now the most affluent part of Riviera Beach.

“They were wealthy people whose family was paying taxes on it for the past 94 years,” Lozman says. The family was so enamored of his “David versus Goliath Doug Pope’s vision of his Oceana Water Resort, a 50­unit hotel 16 miles northwest of Key West in the Gulf of Mexico. story,” as Lozman puts it, that they offered to sell him 25 acres of their submerged land for $250,000. The deal closed later that year.

By the summer of 2016, Lozman had triumphantly towed his second floating home, the Sinatra houseboat, adorned with a banner proclaiming his Supreme Court victory, and anchored it at one of his submerged land parcels. Lozman also announced his intention to build a community of floating homes on his 25 acres.

His waterfront condo neighbors, who lived along A1A, were less than thrilled. Last July, Singer Island residents, fearful of losing their views and property values, petitioned the Riviera Beach City Commission to not grant Lozman street addresses.

Lozman says his neighbors’ expressions of dismay weren’t limited to petitions or pleas to local media. A couple of men in a boat tried to hit him with a drone, Lozman recounts, and someone broke into his houseboat and left garbage bags filled with feces.

“One woman came over and tried to buy my property,” Lozman remembers. When he said no, “she started cursing at me. She wouldn’t take no for an answer.” (E­mails to the Singer Island Homeowners Association, as well as calls to the association’s president, went unanswered by deadline.)

This past August, Lozman’s Sinatra houseboat sank. The cause isn’t known, but Lozman says the fact that a door to the second floor of his houseboat was open, and that several hatches were missing, indicate an intruder may have sunk it. Witnesses also saw people with flashlights near his property prior to the sinking, he adds.

In spite of his best efforts, the home couldn’t be salvaged. The matter is under investigation and Lozman now lives with his girlfriend at an undisclosed location.

Despite the setback, in November Lozman won yet another case, this one forcing the City of Riviera Beach to give him street addresses for his properties, enabling him to obtain permits from the city, state, and Army Corps of Engineers.

Lozman has since changed his mind about creating a community of floating homes in Riviera Beach. Instead he wants to create Tidal House at Renegade, a development of 40 or 50 two­story stilt homes that use a pinion gear system to move with the tides, plus aerodynamic roofs that can withstand high winds.

Terry and Terry Architects, a San Francisco firm run by brothers Alex and Ivan Terry, came up with the design that, Alex Terry tells the BT, was unveiled at an architecture exhibit in Venice, Italy, last summer and is based on exploratory oil rigs.

“They’re kind of a response to changing climate and a lot of issues with tidal action…and places where there is severe storm action,” Alex Terry says, adding that the Tidal House design has also garnered interest in India.

“The stilt home is a superior solution,” says Lozman, who has hired contractor Donna Milo, a former Upper Eastside resident (and one­time Miami City Commission candidate) to build the homes. Lozman hopes to start construction by 2018, adding that he’s already had offers to buy Tidal House residences for $3 million each.

“In Palm Beach County, three million is not a lot of money,” he notes, pointing out that the condos on Singer Island sell for as much as $10 million.

Wayne Pathman is an environmental and land­use attorney. He has served on special committees on sea level rise for the City of Miami and Miami­Dade County, and is chairman of the Miami Beach Chamber of Commerce.

Pathman advocates for extensive changes in urban codes and infrastructure improvements to address the threat of rising seas. He supports actions spearheaded by Miami Beach Mayor Philip Levine ­­ namely, adding pumps and elevating streets to handle flooding.

Pathman has advocated against creating new historic districts in the city’s North Beach neighborhood, arguing that doing so would limit options for property owners in the future, as tidal events become more pronounced. Pathman often reminds people that the insurance industry is already looking at the future impacts of sea level rise in Florida.

But placing floating homes and stilt houses on South Florida’s waterways? “I don’t think people here in South Florida are really ready for floating homes like other parts of the world,” he says. “It has to be explored when sea level rise becomes more of an impact.”

Miami Beach, in particular, has been pretty tough on even common boats anchoring on the city’s waterways, this in response to waterfront homeowners who complain that liveaboards (full time boat residents) invade their privacy. Although a proposed law making it illegal to live aboard a boat full­time was rejected in 2002, the city has recently passed laws forbidding vessels from anchoring in public waters without permission, except for specified areas near the Venetian Causeway.

Dutch architect Olthuis emphasizes that Maule Lake has been privately owned for decades, and he is sure the Amillarah project would be beneficial to the surrounding neighborhoods and the city itself. He points out that the Supreme Court ruling in Lozman’s case clarifies that floating homes without motors are actually homesteads that can be taxed as property. In other words, floating homes can provide cities with revenues.

Olthuis argues that places like South Florida need to start thinking seriously about how climate change will affect living choices.

“You can see that cities like Miami and New York and Guangzhou are the top cities being threatened by sea level rise, in terms of assets,” he says. “Miami has to come up with different kinds of solutions. You have to come up with new technology, and you have to change the DNA of cities. You have to slowly start implementing these kinds of developments that have growing resiliency.”

He’s hopeful that building codes in Florida will soon force developers to build in preparation for a changing environment, much like in his native Netherlands. “In 10 or 15 years, builders will, for the most part, have made the switch to resilient typologies like floating houses or stilt houses in Miami,” he predicts.

Other aspiring builders, like Doug Pope in Jacksonville, think the new administration in Washington will be their ally in removing regulations. A single regulation ­­ dealing with Oceana’s water treatment ­­ stood in the project’s way when it was proposed in 2010, Pope asserts. Then the project fell into limbo when Oceana’s financial backers suddenly balked. Now he is somewhat confident he can find new investors to raise the $26 million needed to build Oceana.

“Things are looking better,” he says. “I wouldn’t say ‘good.’ I would say better.” But why submit yourself to outside governmental regulations at all? Joe Quirk, a science author affiliated with Peter Thiel’s Seasteading Institute, says technology can innovate more quickly if entrepreneurs don’t have to report to government. That’s why the Seasteading Institute wants to create floating­island “startup societies” with their own autonomy.

If the French Polynesia pilot project succeeds, notes Randolph Hencken, the institute’s executive director, he can envision “future seasteads in places like Miami and Bangladesh.” Says Quirk: “In order for us to bring this technology to Florida or Miami, the governments of Florida and Miami would have to legislate us some measure of legislative or regulatory autonomy.”

Absent new discoveries that could clean the atmosphere of greenhouse gases, the oceans will continue to warm and rise ­­ increasingly faster ­­ as ice from Greenland and Antarctica slips beneath the waves, predicts Harold Wanless, chairman of the University of Miami’s Department of Geology and an outspoken climatologist.

Because humans have been burning fossil fuels for more than a century, Wanless points out, the planet has about as much carbon dioxide in the atmosphere today as it did 3 million years ago, a time when there were no polar ice caps and the oceans were 80 feet higher. “This isn’t a cloud of smoke that will just evaporate,” Wanless quips.

The UM professor adds that we won’t have to wait until 2100 to see the full effects of sea level rise. In less than 30 years, he says, tidal flooding will be significantly worse for low­lying areas like Broward, Miami Beach, Key Biscayne, west Miami­Dade, south Brickell, and Miami’s Edgewater and Upper Eastside neighborhoods, along with other areas up and down the Biscayne Corridor. (For more on sea level rise projections, see “Six Feet Under,” June 2015.) According to Wanless, Miami Beach’s expensive efforts to mitigate rising seas will only last a couple of decades.

Wanless says the innovations proposed by Olthuis, the Terry brothers, and the Seasteaders are “nice” and “creative,” but he questions if anyone is going to want to live in a flooded area that will be significantly hotter, ravaged by more powerful storms, and difficult to traverse.

A better idea, Wanless suggests, would be preparing places like Omaha, Nebraska, to accommodate the millions of people who will be displaced from coastal communities in the United States.

Olthuis, however, is undeterred. He’s confident his floating­structure designs can help South Florida adapt to the changes that most scientists agree are certain to come. And in addition to Maule Lake, he has leads on other sites.

“You can imagine that other people with new opportunities have contacted us,” he says. “Developers who are asking if we can do the same for their water.” Olthuis wouldn’t identify those developers or where future floating projects might be located.

“They’re not ready,” he explains. “They must get hold of all their licenses and all their agreements before they start bringing their projects into the open.”

Buoyant buildings: better than boats?

September.16.2016

 

With hurricane season at its peak, we explore how floating homes might help us adapt to bigger storms and rising seas.

The Dutch have a head start when it comes to dealing with water. The extreme weather events and rising sea level that scientists predict this century will affect millions around the globe—most of the world’s largest cities are along the coasts. But that problem has long been acute in the low-lying Netherlands, where two-thirds of the population live in flood-prone areas. Over the centuries, the Dutch have honed technologies—dikes, canals, and pumps—that keep their streets and houses dry.

Now, a new generation of Dutch engineers and architects is modeling another method. Rather than fight to keep water out, they say, why not live on it? The basic idea is not new—hundreds of free spirits live on traditional houseboats in quirky communities like Sausalito, California, and Key West, Florida. But in the Netherlands over the past few years, novel technologies have allowed developers to build roughly a thousand (and counting) stable, flat-bottomed, multi-story homes connected to land-based utilities yet designed to rise and fall with the tides and even floods. House boats, these ain’t.

And this is just the start. The Dutch are thinking bigger, and they’re exporting their floating-home vision worldwide, betting that the rest of us coastal clingers could use it. Some projects exist already, others are on the drawing board or coming soon. Let’s take a look at a few, from the workaday to the fantastical, and from overseas to right here in the States.

A “normal house” on water

The first of its kind, Waterbuurt (above and top) is a planned neighborhood of about 100 (eventually 165) floating houses in Amsterdam’s IJmeer Lake, part of a freshwater reservoir dammed off from the North Sea in the 1930s. Waterbuurt broke ground—er, water—in 2009, and was largely complete by 2014. Connected by jetties, the structures are three-story, 2,960-square-foot houses built of wood, aluminum, and glass.

And the foundations? Floating concrete tubs. Each house is designed to weigh 110 tons and displace 110 tons of water, which—as Archimedes could tell you—causes it to float. (The bottom floor is half submerged.) To prevent rocking in the waves, the house is fastened to two mooring posts—on diagonally opposite corners of the house—driven 20 feet into the lake bed. The posts are telescoping, allowing the house to rise and fall with the water level. Flexible pipes deliver electricity and plumbing.

Because any crack in the foundation tub could cause the house to sink, there can’t be any joints; builders pour the entire basement in one shot—much like the parking garage of the Jade Signaturecondo complex in Florida. In a facility 30 miles away from the IJmeer Lake site, crews use special buckets that pour 200 gallons per minute to finish all four walls and the floor in a single shift.

Just four months elapse before the entire house is built; then it’s towed by tugboat—30 miles through canals and locks—to the plot. The transportation is a major reason the houses cost about 10 percent more than an average home in Amsterdam, though they’re still aimed at the city’s middle class. The houses were designed by architect Marlies Rohmer, for developer Ontwikkelingscombinatie Waterbuurt West.

Once secured to its mooring posts, the structure is formally considered an immovable home, not a house boat. (Although owners have the option of naming their waterborne homes as sea captains do. One couple calls theirs La Scalota Grigia—Italian for “The Grey Box.”)

With high ceilings and straight angles, a house in Waterbuurt “feels like a normal house,” wrote a New York Times reporter who toured one. But some residents say they do feel their home swaying when the wind kicks up.

One other drawback, or at least challenge: Residents have to decide before the house is even built where they’re going to place furniture, because that will affect its balance. The walls are built to varying thickness, depending on the layout submitted. What if you inherit a beloved aunt’s piano after you move in? Or have another child and need to buy a bunkbed? To compensate, homeowners can install balance tanks on the exterior or Styrofoam in the cellar, or carefully move furniture around or even deploy sand bags. A bit of a hassle, but perhaps with an eye on rising sea levels, that’s a risk Amsterdammers are willing to take.

Living large on a lake

At the luxury end of the market, there’s Citadel, which aims to be the world’s first floating apartment complex. Construction began in 2014. Citadel uses the same technology as Waterbuurt—floating concrete base, mooring pistons—but on a larger scale, in the sense that this will be one massive deck supporting a multifaceted apartment building, rather than a place for many individual houses to dock. Think of it as Waterbuurt with butlers. (And underwater parking and other amenities).

Citadel was designed by pioneering architect Koen Olthuis’ Waterstudio in partnership with master developer Dutch Docklands. The concrete caisson foundation will measure 240 by 420 by 9 feet, supporting 60 sleek, aluminum-clad apartments in an irregular arrangement that from the air will look a bit like a scattering of stacks of jigsaw puzzle pieces. Palm trees will sprout from courtyards. Green roofs are planned, and the developer hopes to have Citadel use 25 percent less energy than a similarly-sized complex on land.

One thing remarkable about Citadel is the body of water it will float in: a lake that doesn’t exist yet, though it did once. Construction is taking place in a polder, one of the Netherlands’ many low-lying areas that is only dry because pumps work 24-7 to keep the water out. Once construction is complete, the pumps will shut off, and the area will be re-flooded, to 12 feet deep. Eventually, Dutch Docklands plans to build five more complexes in the same un-manmade lake, dubbed New Water.

Exporting the vision

This is all well and good for the Dutch, but what about the flat, flood-prone coastal regions here in the USA? Like, for example, Florida? Well, the Dutch have thought of that. Another Waterstudio-Docklands project is Amillarah Floating Private Islands Miami, located in Maule Lake. A former limestone rock quarry, the privately owned lake is an inlet a mile and a half from the ocean, a bit north of Miami Beach.

Dubbed a “villa flotilla” by the Miami Herald, the complex will consist of 29 6,000-square-foot condos priced at $12.5 million each. As with Citadel and other Dutch Docklands projects, there are plans to boost the Maule Lake project’s sustainability, in this case with solar and hydrogen-powered generators.

Though similar to Citadel in the Netherlands, this project wouldn’t have been possible Stateside without a 2013 U.S. Supreme Court decision that floating homes could be considered real estate, not boats. As the Herald explained, would-be buyers of Amillarah condos can get a mortgage and homeowners’ insurance, and the Coast Guard can’t bust in and inspect for life jackets.

Maule Lake will be out of reach for most Floridians financially, but if the ambitious project succeeds, it will provide visual evidence to Miami that floating houses can be done, and perhaps inspire larger, more modest developments like Amsterdam’s Waterbuurt.

Not hidebound in the Hub

In Boston, architect Brian Healy, for the local office of Perkins+Will, won awards in 2013 for his design of Floatyard, a proposed apartment complex that would stretch out onto the Mystic River from the Charlestown Navy Yard, using much of the same technology as the abovementioned Dutch initiatives. Were Floatyard and similar projects to become reality here, Healy argues that they would not only help the city adapt to rising seas but also revitalize disused shipyards (for example, in East Boston and Quincy) and reorient Boston—historically a seaport—toward its natural center, the harbor.

What makes Floatyard unique is its central courtyard: a floating wetland island, built above the foundation, to be seeded with native marsh grass and aquatic wildlife. The design also includes a plan to harvest tidal energy via the structure’s mooring post pistons.

Elder statesman of architecture criticism Robert Campbell could have been talking about any of the above floating buildings when he wrote of Floatyard: “Like a lot of good ideas, this one is just crazy enough to make sense.” Given the prediction for the ocean to rise between three and five feet by the year 2100, it might be more crazy not to build on floating tubs.

Ciudades Anfibias

By Beatriz Portinari
CLUB + RENFE

 

Los arquitectos del futuro proponen una Atlántida biososteniblecomo respuesta al cambio climático y la utopía de una colonización oceánica.

“El mar no pErtEnEcE a los déspotas. En su superficie, aún pueden ejercer sus inicuos derechos, pelearse, devorarse y transportar todos los horrores terrestres, pero a treinta pies de profundidad, su poder
cesa. ¡Ah, señor, viva usted en el seno de los mares! ¡Solo ahí existe la independencia! ¡Ahí no reconozco señor alguno! ¡Allí soy libre!”. Con estas palabras, Julio Verne convirtió al capitán Nemo y su Nautilus en los pioneros de la llamada “colonización oceánica”, en 1870. Casi 200 años después de 20.000 leguas de viaje submarino, ingenieros y arquitectos ofrecen propuestas viables que van desde hoteles flotantes o flotels a cruceros-residencia para millonarios como The World y finalmente la utopía social y política de las naciones semi-sumergibles que propone el Seasteading Institute.
Pero, ¿por qué querría el hombre vivir en futuristas ciudades acuáticas?
Quizá por placer, por evadir impuestos en aguas internacionales o por pura necesidad medioambiental. Según los expertos en cambio climático y el Informe España: hacia un clima extremo, publicado por Greenpeace en 2014, se espera que a finales del siglo XXI la subida del nivel del mar por el deshielo del Ártico provoque una catástrofe climática y humanitaria que afectará al uno por ciento del territorio de Egipto, el 7% de Países Bajos, el 17% de Bangladesh y hasta el 80% de las Maldivas. En España, las mediciones indican que “durante la segunda mitad del siglo XXI, hasta 202 hectáreas de terreno se encontrarán en riesgo de inundación en la costa vasca. De esta extensión, la mitad corresponde a terrenos urbanizados, tanto zonas industriales como residenciales”. El peligro es real. Las estimaciones más pesimistas dicen que en 2030 habrá 50 millones de refugiados climáticos en el planeta, que ascenderían a 200 millones en el año 2050. ¿Qué hacer con esta población sin tierra? Más allá de previsiones, la evidencia está en el archipiélago de Kiribati, al noreste de Australia, donde 100.000 habitantes buscan territorio para trasladar todo un país porque el suyo ha comenzado a desaparecer bajo el mar. El gobierno de Kiribati ha comprado terreno en las islas Fiji para instalar a su población e incluso se ha planteado los diseños anfibios de uno de los arquitectos más preocupados por el medio ambiente, Vincent Callebaut, autor de los prototipos acuáticos Lilypad, Physalia y el más reciente Aequorea.

‘aRQuibiÓTica’ conTRa El cambio climáTico
“La anticipación urbana es fundamental para crear la ciudad del mañana, que considero imprescindible en la transición energética. Lo que llamo ‘arquibiótica’ es la solución
biotecnológica de la arquitectura a la crisis ambiental que sufrimos. Me inspiro en el biomorfismo, el biomimetismo y
la biónica, donde la ingeniería puede repetir esquemas de la naturaleza y aprovechar las nuevas tecnologías de comunicación”, explica Callebaut, a quien el Ayuntamiento de París
acaba de encargar el rediseño de la ciudad. De momento, sus audaces prototipos todavía no han encontrado océano donde iniciar la revolución verde.
Quien sí ha comenzado la construcción real de un atolón artificial para salvar a su población del mar es el Gobierno de las islas Maldivas, que ha firmado una alianza comercial con la empresa holandesa Dutch Docklands, experta en ganar terreno al agua. Si el entorno paradisíaco de las Maldivas va a desaparecer bajo el mar, nada mejor que empezar a construir una réplica flotante para mantener el turismo. Para ello se ha encargado el proyecto The 5 Lagoons al estudio de arquitectura Waterstudio, que dirige Koen Olthius, considerado “uno de los 100 eco-arquitectos que cambiarán el mundo” y que apuesta por el paso de las ciudades verdes a las ciudades azules sobre el agua. “No debemos tener miedo al posible aumento del nivel del mar, sino verlo como una oportunidad para mejorar nuestras ciudades. Si la costa española se puede ver afectada, debería empezar hoy mismo a considerar soluciones. Estas plataformas flotantes deberían ser eco-sostenibles, más duraderas y flexibles”, cuenta Olthius. El arquitecto va más allá e imagina “bellos parques en el agua, dinámicos, capaces de cambiar de forma y función en cada estación; el turismo ha sido siempre muy importante en la economía española y creo que estas extensiones flotantes podrían atraer más turistas.
Podría aportar al mismo tiempo seguridad y prosperidad a la costa. La tecnología está disponible, sólo sería necesario que fuera económicamente viable”.
El Seasteading Institute, creado en 2008 con importantes inversores como Peter Thiel, fundador de PayPal, va más allá y propone ciudades-estado independientes en aguas internacionales. Sin embargo, su utópico proyecto Floating City aún no ha visto la luz. “Técnicamente las ciudades anfibias son viables, pero deberían responder a una necesidad económica, legal y política real porque de lo contrario el proyecto no es rentable. Si tienes una plataforma que no pertenece a ningún país, no puedes defenderte de ataques piratas, por ejemplo. Para el problema del cambio climático existen soluciones más baratas como se ha visto con el relleno de tierra que está haciendo Singapur en su costa”, advierte el Ingeniero Naval y Oceánico, Miguel Lamas, experto en plataformas flotantes y antiguo colaborador del Seasteading Institute. En su tesis Establecimiento de comunidades autónomas en alta mar: opciones presentes y evolución futura hace un análisis realista de los posibles escenarios. Aunque estas comunidades en alta mar serían beneficiosas porque fomentarían el uso de las energías renovables de origen marino y la protección del hábitat oceánico, hoy por hoy no existe economía ni sociedad que respalde a corto plazo un costoso proyecto como las Ciudades Flotantes autónomas. Parece que la utopía de la colonización oceánica tendrá que esperar.

Why Blue is Better

Annelie Rozeboom
Hi Europe
October.2015

 

Architect Koen Olthuis draws on a roll of paper while explaining why we should be building our cities on the water and how he is planning to help the poor with his ideas. “As an architect, you can design towers, but every child can do that in their Minecraft game. Plus none of the towers we build now will be there in 300 years’ time. What I want to leave behind at the end of my career are concepts and ideas, the main idea is that we need to push our cities unto the water.”
Green is good, blue is better is the motto of this Dutch architect. “Our cities don’t change fast enough. We build houses and building and expect them to be used for ever, but our society changes every ten years. If parts of our cities float, we are much more flexible. The center of Amsterdam will always be the same, but the neighborhoods around it change all the time. If buildings float, you can just pull them away and put them somewhere else,” Olthuis told Hi-Europe.

Working with the Water

One-half of the Netherlands is flood-prone and about one-quarter is below sea level, so it’s no wonder the Dutch spend their time developing ways to incorporate water into their style of living. The philosophy is shifting from fighting the water to living with it, or rather, on it. Instead of trying to claw back more land from the sea, developers are exploring the cost-efficiency of building homes that rise and fall with the tides. “We need to start working with the water in a more intelligent way,” Olthuis says.

This relatively new amphibious architecture is attracting interest from around the world, with floating and amphibious homes and schools now being designed for flood plains everywhere. Amphibious architecture is for both dry and wet conditions, so the houses stay dry and on the ground during normal times and then when the water arrives, they can float up.

Waterstudio

Olthuis wants to do much more than build a few villas. His architectural bureau Waterstudio.NL has designed complete apartment complexes, which could accommodate hundreds of people. And that is just one project. There is also a 33-meter-tall trees that can float. “Our cities have become sick environments. Green has been pushed away, but bees and other insects need quiet places. Our sea tree is like a cut-up park, which floats at a safe distance from the shore. Nature will take over on the platform and create its own ecosystem.”

Olthuis is also planning to help people in the slums of the world, which are often located on flood plains. “Worldwide you see that the most vulnerable people are being pushed into the water,” he says. This coming month he will send a floating school to Dakar – it’s a container that floats on empty plastic bottles. “The way to upgrade a slum is by installing facilities like schools and internet cafés, or easily movable small buildings that slum entrepreneurs can use. We have designed a kind of toolbox, which have 20 functions inside. This way, the entrepreneurs can choose what it is they need.”
Olthuis exports his concepts all around the globe, including to the flood zones of Hainan Island. “They have land there that they can’t use, but they will if they take our technology.” He also sells floating islands to Dubai. “Making artificial islands out of sand doesn’t work. In Dubai they built some, but they are too far away from the coast, and there is no electricity or drinking water. We are now going to put floating islands in between.”

Fight Against the Sea

The Dutch are famous for their age-old fight against the sea, and they have the best flood management technologies in the world. In the beginning, the people in this low country put their homes on artificial hills called terpen, but they soon started building dikes. Popular in the middle ages were wierdijken, earth dikes with a protective layer of seaweed. Later dikes had a vertical screen of timbers backed by an earth bank, but these were replaced by stones after the timber was eaten by shipworms. When the polder windmill was invented in the 15th century, it meant that land could also be drained.

The dikes around the rivers were maintained by the famers who lived next to them. Special water board directors would come to check every three years. This changed radically after a devastating North Sea flood in 1953, which resulted in 1,800 deaths. The government adopted a “never again” attitude, and built dams all around the country, guarding all main river estuaries and sea inlets. According to computer simulations, today’s defenses in the Netherlands are supposed to withstand the kind of flood so severe that it would occur only once in 10,000 years.
“We have pretty much won the fight against the sea,” architect Olthuis says. “The problem now is rainwater. Holland has 3500 low-lying polders enclosed by dykes that function as sponges – they soak up excessive rain water. However, more and more of this land is now used for housing. These are ideal places to build amphibious houses.”


Pict: Architect Koen Olthuis – Waterstudio.NL

Rising Sea Levels

Dutch scientists predict a rise in sea levels of up to 110cm by the year 2100. “We can make the dikes higher, that’s not a problem at all. Technically, all that is possible. The problem with a high dike is that when it breaks, more water will come in,” he says.

There is also growing pressure on existing land. The Dutch government estimates that 500,000 new homes will be needed in the next two decades. Most of the land suitable for conventional building has already been used up, so Dutch architects are encouraged to experiment with new solutions. “The palace in the center of Amsterdam was built on 13.654 wooden poles. It’s the densest forest in the Netherlands. There was real innovation in those times. We are built on places where there shouldn’t be land at all. It’s not about giving up, it’s about continuing to grow,” says Olthuis.

Holländskt flyt mot stigande havsnivåer

By Sebastian van Baalen
Syre
August.2015

 

Sebastian van Baalen – 2 år sedan
Han kallas den flytande holländaren och har utsetts till en av världens viktigaste tänkare av the Times. Koen Olthuis är en nederländsk arkitekt som propagerar för att holländarna måste lära sig att leva med stigande havsnivåer. Men hans
idéer har implikationer långt bortom Nederländerna.

Med hjälp av cityappar vill arkitekterna på Waterstudio tillgodose grundläggande behov i världens vattennära slumområden. Foto: Sebastian van Baalen

Nederländerna är ett av världens lägst liggande länder med omkring 20 procent av landets yta under havsnivå och ytterligare 30 procent i riskzonen för omfattande översvämningar. Men trots århundraden av erfarenhet av att bygga vallar, kanaler och pumpstationer menar arkitekten Koen Olthuis att framtiden ligger på vattnet. Han har patent på flytande husgrunder och de senaste tolv åren har han ritat över 100 flytande hus i Nederländerna.

– Lösningen fanns i familjen hela tiden, förklarar han medievant. Min mammas familj jobbade inom skeppsindustrin och min pappas familj var arkitekter. Jag har helt enkelt tagit det bästa av två världar.

Enligt Koen Olthuis är flytande byggnader lösningen på flera olika problem; stigande havsnivåer, platsbrist i storstadsområden och behovet av dynamiska städer. – Städer är inte perfekta, de är korkade. Världen förändras ständigt men städerna är statiska och kan inte anpassas snabbt nog. Genom att bygga på vattnet kan man göra staden dynamisk, funktioner kan distribueras dit de behövs, när de behövs.

Lyxbostäder och konstgjorda öar signerade Koen Olthuis finns bland annat i Dubai och på Maldiverna. I Nederländerna, ett land där platsbristen är akut, har Koen Olthuis idéer resulterat i flytande bostadsområden. I sin bok Float! propagerar han för att användningen av flytande husgrunder kan möjliggöra så kallad depolderisering i Nederländerna, det vill säga att grundvattennivån tillåts stiga i torrlagda områden. Men det var när han uppmärksammade problemet med slumområden som han insåg konceptets fulla potential.

Flytande cityappar

Enligt FN förväntas omkring två miljarder människor leva i slumområden år 2030. Dessa bosättningar är ofta semitemporära då invånarna ständigt hotas med avhysning eftersom de formellt varken äger marken eller sina bostäder, något som försvårar utvecklingen av samhällsfunktioner i dessa områden. Men detta vill Koen Olthuis ändra på med hjälp av flytande cityappar.

– Många av världens slumområden ligger vid eller på vatten. Men när vi gjorde en studie i Bangladesh nämnde sluminvånarna förvånansvärt nog inte översvämningar som det främsta problemet – det var bristen på samhällsfunktioner. Och då är vattnet lösningen!

Precis som man laddar ner appar till sin smarta telefon för att ge den funktioner som saknas menar Koen Olthuis att man kan lägga till samhällsfunktioner i vattennära slumområden. Tillsammans med ett team av unga ingenjörer och arkitekter på sitt företag Waterstudio i Haag har han utvecklat flytande containers som huserar skolor, internetkaféer, sjukhus och sanitetsanläggningar, alla drivna av solpaneler. Dessa kan fraktas till slumområdena till havs. Jiya Benni jobbar med projektet.

– I de flesta slumområden saknas de juridiska förutsättningarna för att utveckla infrastrukturen. Fördelen med dynamiska cityappar är att de inte kräver bygglov. Skulle förutsättningarna förändras kan apparna helt enkelt bogseras bort.

Den första containern är nu på väg att placeras i Dhaka i Bangladesh. Men flytande cityappar ska främst ses som ett socialt företag enligt Jiya Benni.
– Varje cityapp har en affärsidé. Tanken är att lokala entreprenörer i slumstäderna kan hyra en city app på lång sikt och betala av kostnaden över tid. När appen har spelat ut sin roll i ett visst område kan den helt enkelt flyttas vidare. Lite som ett mikrolån.

Samtidigt erkänner Koen Olthuis att kostnaden för cityapparna än så länge är för hög.

– En flytande skola kostar för närvarande 45 000 dollar. Vi måste minska priset till 18 000 dollar för att det ska bli ekonomiskt hållbart.

Marinbiologer har bland annat påpekat att flytande byggnader kan störa de marina ekosystemen. Men Jiya Benni ser inte det som ett problem. – Jämfört med att torrlägga land är flytande byggnader definitivt mer miljövänliga. Visst kan konstruktionerna påverka mängden ljus som når botten, men det går att lösa med kreativ design. Vi samarbetar med oceanografen Jean-Michel Cousteau för att utveckla våra cityappar till naturliga ekosystem för fiskar.

Vatten som möjlighet Koen Olthuis framstår lika mycket som visionär som arkitekt. I hans visioner ingår flytande grönområden, flytande flygplatser och mobila och flytande flyktingläger.

Men vad är science fiction och vad är verkligen möjligt?
Faktum är att flytande städer har existerat sedan länge och stora slumområden ligger i dag på vattnet. Ett exempel är slummen Makoko i Nigera som är hem åt tiotusentals människor. Liknande samhällen återfinns i Hong Kong och Vietnam. Investeringar i sådana områden är ofta riskfyllda då infrastruktur riskerar att förstöras vid översvämningar. Även rikare länder har insett såväl nyttan som det estetiska med flytande byggnader; Seoul har en flytande ö på Hanfloden, Rotterdam ett mobilt konferens- och utställningskomplex på Nieuwe Maasfloden och Bristol en flytande plantträdgård. Men för Koen Olthuis handlar det om att förändra hur vi förstår staden.

– Mitt budskap är att vatten inte enbart är ett hot, utan också en möjlighet. Jag hoppas att det vi gör, mina idéer, kan spridas och locka människor att tro på idén. Min vision är att förbättra städer i hela världen.

Amillarah, een privé eiland die je zelf kan customizen

By Gewoon voor hem
August.2015

 

Amillarah, een privé eiland dat je zelf kan customizen! Jep, voor de superrijken gaan de mogelijkheden steeds verder en verder.

Volgens Amillarah, wat overigens staat voor privé eiland, zit er één groot nadeel aan het aanschaffen van een privé eiland; de locatie. Vrijwel altijd liggen ze erg afgelegen en zijn de meeste faciliteiten erg kostbaar. Dat is dus verleden tijd, de eilanden zijn geplaatst in een bepaalde zone met de faciliteiten die nodig zijn binnen handbereik. Verder zijn de eilanden te customizen qua indeling en formaat.

De eilanden zijn ontworpen om minimaal 100 jaar in top conditie te blijven, hebben totaal geen (negatieve) impact op de natuur en zullen tevens zorgen voor een prachtige onderwaterwereld die zich kan nestelen onder en rondom jouw stulpje.

Er worden er maar 43 gemaakt, dus zorg dat je er snel bij bent enne.. nodig ons ook even uit!
