As many coastal cities struggle to come up with resiliency plans in the face of rising sea levels, Dutch architect Koen Olthuis with Waterstudio is creating sustainable, solar-powered floating residences that could offer the perfect solution. Already well-known for its high-end floating homes, Waterstudio and Miami-based Arkup are now teaming up with Artefacto, an environmentally friendly Brazilian furnishing brand, to create stylish floating houses that are not only resilient to storms and sea levels, but also represent the luxury style for which Miami is known.

Waterstudio has long been recognized for creating sustainable and attractive floating homes that can provide discerning homeowners with an “avant-garde life on water.” The residences are modern, cube-like structures that are completely self-sufficient, operating 100 percent off-grid thanks to solar power generation, eco-friendly waste management features, rainwater harvesting and water purification systems. Additionally, the homes are equipped with unique self-elevating systems that help the structures withstand high winds, floods and hurricanes.

In addition to the ultra sustainable and resilient features, the two-story floating homes boast interiors with a 775-square-foot living room, bedroom, kitchen and dining space, as well as an open-air rooftop lounge. Sliding glass doors, which almost make up the entirety of the front facade, lead out to a beautiful terrace.

Although the company has been working on its floating homes for some time, it recently announced a new partnership with Artefacto, a Brazilian furnishing company with a strong commitment to sustainability that is known for combining luxurious furniture made of raw materials with cutting-edge smart automation technologies. The floating residences will now be outfitted with eco-friendly furnishings, including high-end pieces made out of timber approved for use by the Brazilian Environment Department.

In light of all the dire news related to climate change, rising sea levels and the natural disasters which have stricken numerous coastal areas around the world, we here at Inhabitat would like to highlight an interview Inhabitat Editor-in-Chief Jill Fehrenbacher conducted with architect Koen Olthuis of Waterstudio.nl. A studio focused on designing for a future water world, Olthuis has been at the forefront of this once unconventional, yet now timely design vernacular. Olthuis says that despite our civilization’s history of trying to drain and fight against wet landscapes for the past thousand years, our best move for the future would be to “let water in and even make friends with the water.” Read on for the fascinating interview where Olthius describes his what designing for water landscapes worldwide really means.

You have to trust an architect who has grown up in a landscape completely engineered for water. Roughly a third of the Netherlands lies below sea level, and is home to over sixty percent of the country’s population of 15.8 million people. The Dutch have spent the last thousand years constructing dikes, pumps, and drainage systems in a constant battle to keep the encroaching North Sea at bay. On my recent trip to the Netherlands, I was fortunate to get the chance to sit down with architect, to discuss amphibious dwellings, floating foundations, and his experiences designing for water landscapes worldwide.

 

Jill: So Holland is almost completely built on wetlands, right?

Koen: Yes, the landscape is completely artificial. It’s fake in the sense that we have pumped out all the water, created dikes, and if you don’t have those dikes, then this would all be under water. The problem is we have three and a half thousand areas like this. It is amazing. And if you ask just somebody in Holland, they don’t even realize it. People in Holland are so used to the idea that I think nobody knows what the risks are anymore. And people from the United States and China, watch our systems of keeping the water out of the landscape the water out. But while they want to emulate our system of dikes, we are actually trying to move away from fighting against the water. Now we are beginning to let the water in and we are starting to make friends with the water. We have to do that because eventually the dikes won’t be able to keep up and all of this part of Holland’s will be flooded. So, its better just to work with the water instead of fighting against it.

Jill: How did Holland get like this in the first place?

Koen:: Well, when the first people came here from France and Germany, they came to the coast and they found space to live in this swamp and they created little artificial hills – what we call terpen. And between each hill was swamp. And then they created dikes from one hill to another hill in order to keep them dry. And then after awhile, you have one, two, three, four terpen – artificial hills with dikes around them, you say okay, why don’t we just pump out the water in between it. And so this gradually became dry land – what we call a polder. Only the people had to pump out the water constantly. Because if you stop pumping, then in 48 hours, a polder will be flooded again with 30 to 60 centimeters water. That means that if you stop pumping, this will all be water immediately. And so, Holland is completely artificial, because we just keep on pumping – Well, three and a half thousand polders constantly pumping out the water is a problem at times when there is a lot of rain and the river gets too high, and when the sea water level is high…

Jill: Some of your houses are floating, some of them are raised and some of them are amphibious. Can you explain the difference? I mean, I see houseboats all over Amsterdam – how are your buildings different from houseboats?

Koen:: Well there’s 60,000 houseboats in Amsterdam, but all of those have dimensions of five to six meters by 20 to 25. We’re doing something completely different, which allows the buildings to get much bigger and be a lot more stable. We have a patented technology to create special “floating foundations” with foam and concrete – what we call floating land. These foundations move up and down on piles. This allows us to go up to 200 – 200 meters in dimension and create larger structures. We use the term amphibious to describe these floating foundations that rest on piles. The foundation is set on dry land, and when the water comes, the foundation comes loose from those piles and floats upward, and become a floating house.

Jill: How did you get started in this business in the first place?

Koen:: We did a few designs for Amsterdam on the water, and I loved it. That’s what got me hooked. And I think, well, this is the choice I have to make. The first years were very hard, and now it’s getting easier.

Jill: How many houses and buildings have you actually built? I see a lot of CAD images of projects in the works, but not a lot of photos.

Koen:: We’ve built I think 24 houses now. But most of them — I think around 20 — are just modern houseboats. They are a little fancier than a normal house, but still they are houseboats.

I think we’ve built four really architectural, beautiful, unique buildings, and then we have 27 or 28 projects currently in the works, like the floating mosque in Dubai, like the floating boulevard in Antwerp, like the Health Village in Aruba.

The thing about our technique of working with the water is that the buildings and the floating foundations require very little maintenance. With these floating house techniques, waterproof houses, apartments, everything, you can just go on top of the normal structure of the polders and keep the original landscape in the same way as it is.

Jill: It sounds like it’s much more efficient and better for the environment. You don’t have to do anything to maintain it?

Koen:: Yeah, that’s correct. The only thing you have to be sure of is that the water quality underneath those big structures is alright. And that depends of the amount of oxygen, how the sand gets underneath your platform, the current…well, lots of factors. This works for a lot of places. It works for Amsterdam, Rotterdam, Antwerp, Copenhagen. People have now been calling me from Tokyo, Ho Chi Min City, Bombay, Budapest.

Jill: Well, that makes sense, because every major city has water, doesn’t it?

Koen:: Yeah, that’s why they’re cities! In the newspapers we are always preaching “the floating city has a future,” and then everybody say, ah, I don’t know. Then when we show them Amsterdam, for instance, Amsterdam has more water than Venice. The whole city is made up of tiny islands on piles. There are thousands and thousands in Amsterdam, because it’s such a bad soil. If you look at Venice, the whole city is a static city. If they could have built it on a floating foundation just a few years ago, then the whole city would go up and down with the water, instead of constantly having to be drained.

Koen:: The most interesting city for us right now is Dubai. There’s amazing investment going into the waterfront right now, and it’s the first place where people are actually designing and building right in the water. We were asked to design a water taxi, and when we showed them that design they liked it so much that they wanted more. Now we are working on structures for part of the Palm resort and also this floating mosque. That will be for the Waterfront area.

ill: Do you have anything in the U.S. in the works?

Koen:: No. It’s very hard to get plans realized in the United States. They’re very protective. Even for New Orleans. We have to find people already doing the work and then help them as a co-architect. But it’s not possible to get your own assignment over there. It’s really strange, because in other countries, such as Canada and England or Australia, we’re welcome. We can bring ideas in and get assignments. But the U.S. is a little bit protective of the market. And I think they should open up a little bit.

Jill: From what I can see in New Orleans, they could certainly use the help!

Koen:: Yeah. In the states, the problem is if there’s a big disaster like Katrina, then all the media totally focuses on that problem. And everbody gets really excited and says, “Okay, we’ve got to solve this.” But then a few months later, nothing has happened. And then the problem is no longer the focus of the media, and it’s back to the same old, waiting for the next disaster….

What you should do is make a real plan and do it a new way. Because when you get an innovative idea, the innovation brings in new economical possibilities. For example, we’re not a company who can have industrialized factories because labor is very expensive over here. But due to high standard of technical innovation we have here, we can sell our ideas and our expertise around the world. And it should be the same for the United States, in which labor is also very expensive, but innovation and technology standards are high.

Parthenon, The Floating Sea Wall

Inhabitat, Tafline Laylin, December 2015

Certain world leaders might be dragging their feet on addressing climate change, but in the meantime, Koen Olthuis and the rest of the Waterstudio crew are working on solutions that we can use today. The Blue energy floating sea wall is a floating breakwater that doubles as an energy generator. Called The Parthenon, the floating breakwater not only stems the crash of water pushing into a harbor, but harvests the tremendous energy a wall of water like that can generate.

Waterstudio used the Hudson River to illustrate their new design’s function. “In a harbour on the Hudson river in New York the wave conditions are so strong that a sea wall must protect its boats. The strong current in the river is constantly attacking it and water is pushing itself against and through the fixed wall, which results in more corrosion of the sea wall every year.”

The floating sea wall acts as a permeable breakwater that converts the wave power into electrical energy while reducing the waves’ impact on the harbor at the same time. “The floating breakwater lives with the force of the river instead of fighting it,” they told Inhabitat in an email.

The columns of the sea wall are comprised of 3-foot cylinders that rotate – both clockwise and counter clockwise – at low speed. The energy created by this rotation is then captured in a concrete box inside the floating platform. The cylinders are filled with water to give the structure flexibility without affecting in any way the efficacy of the wall in reducing the wave’s impact on the harbor. The whole thing is then anchored to the riverbed, and the top can double as an urban green space or boulevard.

“The Parthenon blue energy sea wall resembles the column structure of the famous ancient temple in Greece,” according to Waterstudio, “but divers see it as a part of the sunken city of Atlantis.”

Water Architect Koen Olthuis on How to Embrace Rising Sea Levels

Inhabitat, Bridgette Meinhold, July 2014

Sea levels are rising, floods are prevalent, and cities are at greater risk than ever due to climate change. Now that we’ve accepted these facts, it’s time to design and build more resilient structures. Koen Olthuis, one of the most forward-thinking and innovative architects out there, has a solution for rising sea levels. His solution: Embrace the water by incorporating it into our cities; creating resilient buildings and infrastructure that can handle extreme flooding, heavy rains, and higher water. Olthuis and his team at Waterstudio.nl have been showing coastal communities the benefits of building on the water. With countries like the Maldives and Kiribati having to build oceanside or move in order to escape rising sea levels, New York learning to battle storm surges, and Jakarta dealing with massive flooding, embracing water may be our only option for survival. We chatted with Olthuis about how coastal cities can become more resilient in the face of change—read on for our interview!

Despite his busy travel schedule, Olthuis had a chance to answer our questions with a great amount of detail and thought. Not only is Olthuis a leader in designing floating architecture, he’s the most-interviewed architect on Inhabitat. We think very highly of his work and ideas, and we think you’ll agree after reading through his thoughtful answers about the pressing issue of climate change. Don’t worry, it’s not all gloom and doom though—Olthuis proposes a future full of hope and promise!

Inhabitat: What does climate change mean for cities on the coast, and how serious is a sea level rise of 1 meter?

Koen: I think that climate change is a serious problem for these cities because most of them have been built upon the wrong parameters. For centuries, sea levels and climate have been relatively stable, which has brought us urban plans and built environments that are too static—like a one-trick pony for one certain set of conditions. With the arrival of uncertainty in , we have to rethink our coastal cities.

The threat that climate change brings is not just the physical threat of floods and drowning, but also the financial impact of destroyed property and businesses. Through the last century, waterfront development has increased in value as well as assets. Flood threats will put pressure on available dry space and reset the parameters for which parts of a city are desirable, and which are dangerous.

The effect of a one-meter sea level rise (without any adjustment to coastal cities as they stand today) would completely reset maps and financial stability in many of the world’s biggest waterfronts. New York, Miami, and Guangzhou would lose an important part of their real estate to the water. Countries like Bangladesh and the Philippines would have to give up lots of land. In the Netherlands, many of the water defense systems that protect the country under sea level will no longer be safe.

The question of how serious a one-meter sea level rise would be cannot be answered without placing this question in a certain timeframe. Although cities may appear static, they’re in constant change. The lifespan of urban components like infrastructure, normal buildings, and water defense measurements isn’t more than 50-100 years. This means that if the change occurs within the next 50-100 years, cities have time to grow into components designed upon the new parameters. If the rise occurs faster, cities won’t have time to adapt naturally and problems will occur. The problem is that because sea level rise is quite slow, governments find it hard to deal with a long timeframe when short-term strategies will lead to immediate benefits.

Inhabitat: What do coastal cities need to be thinking about and planning for in order to prepare for the inundation of water?

Koen: First, they have to design plans with flexibility—not solely for today’s conditions. Second, they might be better off embracing the water instead of fighting it, seeing urban water as a chance to upgrade our cities rather than a side effect.

I think that a resilient city isn’t one that prepares for the water to come, but one that allows it to expand. By letting in water and making it part of the city, rising levels or storm conditions will only mean working with a bit more water instead of the big shock that comes when conditions go from dry to flooded.

Regarding planning, coastal cities should focus on which areas should be kept absolutely dry, which can be changed from dry to wet, and which existing waters can be used for expansion. The future of resilient coastal cities is on the water, and metropolises like London, Miami, Tokyo, and Jakarta will expand their territory by 5 to 10 percent on urban waters in the next 25 years.

Inhabitat: Can you give us examples of any cities making promising strides to become more resilient?

Koen: Many are slowly taking defensive measures to become more resilient, but there is one that seems to use a highly innovative path: Jakarta. This capital of 10 million is suffering not only from climate change, but also from urbanization. The soil is sinking at a speed of 15 centimeters per year, which raises flood risks and effects, and it’s getting polluted with saltwater, which has a huge effect on fresh water reserves. Instead of building only higher water defense systems like dikes, which wouldn’t solve the saltwater problem, they’ve chosen to embrace more innovative solutions provided by Dutch engineers and urban planners. The solution focuses on closing Jakarta bay with a dike, turning it into one big 100 km2 wet polder; a size needed to provide enough storage area for extreme weather conditions.

On this dam, a city of a million people will be built facing the old waterfront of Jakarta on one side and the ocean on the other. For architects focusing on floating architecture, this kind of artificial large-scale wet polder provides a big opportunity: in order to keep the storage as big as 100 km2 you cannot build in the water, but floating structures have no effect on storage capacity. Jakarta can become one of the most resilient coastal cities of Asia and still make money from these measures—fighting water with water by adding the storage polder.

Inhabitat: If you were put in charge of making, say New York City, resilient to flooding and climate change, what strategies would you implement?

Koen: New York is one of the most iconic cities in the world, and Manhattan is the benchmark for high-density urban developments, but this city has also evolved to accommodate the surge for space. The enormous land expansion over the river beginning in the 17th century provided the city with new space. The elevator facilitated building into the air, and the metro system took advantage of space beneath the city. Without any of these innovations, Manhattan would look completely different. The lesson here is that standing still doesn’t always benefit cities, and innovations (daunting though they may appear) can bring new prosperity.

The biggest problem that New York will have to face isn’t a steady one-meter sea level rise—because that can be overcome with a meter-high levee—but the effects of extreme weather. Storm conditions like Hurricane Sandy will raise water a few meters and yield heavy rainfall that cannot be transported to the river, since the river itself will rise to record levels. To keep the subway system dry in normal conditions, huge amounts of water have to be pumped out; any additional water could make the system flood.

New Yorkers haven’t embraced the waterfront as much other coastal cities. The view inside is more important than outside and the most valuable real estate can be found around Central Park. [There are] no nice boulevards like in the south of France; nice beaches or green habitats can be found at their manmade border between land and water.

Having said this, I would bring the strategy of fighting water with water to New York and start wetting up the city. If we raise the level of the water ourselves by a few meters, it won’t be any problem when nature does it. To raise the level of the river and still use it as such is impossible, but there’s another Dutch solution that could work. In Holland, existing polders are surrounded by artificial canals. The water in these canals is a few meters higher than the polder waters. They aren’t dug into the landscape, but put on top of the landscape with a dike on both sides to keep the water in. Water from the polder is pumped into the canal and then transported to the rivers or the sea. The canals can be artificially controlled, providing a kind of buffer, and can also be used for transport, and waterside houses. I’d like to create a necklace of small, connected artificial lakes around Manhattan; a system much like an extra canal with a higher water level than the surrounding rivers. This canal would be divided into sections that could be closed separately.

This new zone will take the place of the existing harbor quay—the river width wouldn’t be affected, but the result would be like a set of airbags around the city. In case of high tide, these cells would serve as storage polders that could release water when the storm had passed. These cells would change the edge of Manhattan: the water cells would look like small lakes, and new settlements could be built on the levees dividing them from the river. These lakes would all be connected, and they’d only be closed off from each other during storm conditions, like compartments in large cruise ships.

The artificial lakes would fill the space now used by the river docks, and have a flexible water level that would provide an enormous storage zone, providing safety encroaching seawater. As I imagine, there would be as many as 40-50 of these lakes, each as long as 4-6 blocks. Lakes for leisure, for green floating communities, lakes with harbors—the greener the better.

Inhabitat: With countries like the Maldives and Kiribati losing their land to rising sea levels, how do they respond and provide for their citizens? Buy property elsewhere or construct floating cities? Are there estimates on how much it would cost to construct floating countries?

Koen: The Maldives and Kiribati are both series of small islands in the middle of the ocean, which will be highly affected by any sea level rise. Without enough dry land available, these countries have to make the choice to become climate refugees or adopt floating technologies and become climate innovators.

In the Maldives, Waterstudio has designed floating island resorts and a golf course for developer Dutch Docklands. They are building a joint venture with the government of the Maldives, both as a tool to increase new possibilities for tourism, and to reinforce society with long-term floating developments. Floating islands with high-density affordable housing could be added to the existing islands to provide space and safety. Floating developments are scar-less and mustn’t have any impact on marine environment during or after their lifespan.

This could lead to floating countries, keeping in mind that the Maldives has 300,000 inhabitants. The cost of these floating islands is comparable with dredging islands, only that dredging destroys sea life and coral reefs. If I must make a reasonable guess I would say around $25,000 per person,  so for a city of 20,000 people it would cost 500 million dollars. This might sound like a lot, but it’s quite reasonable compared to evacuating a nation.

Inhabitat: How has your work changed over the years in response to the pressing needs of climate change?

Koen: The possibility of improving coastal cities worldwide with the implementation of floating urban components is just so challenging. It feels like we have only just discovered a small part of the potential that water could bring in making cities more resilient, safe, and flexible. I believe that projects like these will set new benchmarks for cities that would otherwise be in trouble because of climate change.

Our research seeks to change perception and dogmatic rules that traditional planners from the static era have put on us. I think that just in the last two years, iconic designs like the floating cruise terminal have developed an extra dimension—they’re part of a bigger vision that looks beyond iconic architecture to the economical impact it could bring.

My work has gone from designing for rich individuals to designing for the poor. We now design strategies for cities that have to adjust their planning approach because of shifting conditions due to climate change. The focus on slums has opened a whole new window of opportunity and has brought me in contact with many people who believe architects must use their influence and creativity to make a change for millions instead of only the happy few.

Inhabitat: Tell us briefly about your latest project, City Apps, and how it can help cities deal with climate change.

Koen: Miami and New York are the cities most threatened by sea level rise in terms of exposed real estate, but the populations most threatened by sea level rise  would be in Mumbai, Dhaka, and Calcutta. In these cities, millions live in dense slums close to water. In fact, one billion people worldwide are living in slums, and half of them can be classified as wet slums because of their relation to the water. People living in these areas are terribly vulnerable to flood danger. Efforts to help these cities should not focus on protecting the built environment, but on protecting essential functions during and immediately after floods. Slums can be helped by upgrading programs to improve life conditions for 100 million people before 2020, as stated in the 2003 UN habitat millennium goal.

Programs in wet slums are not generally upgraded, because investing in them is a risky business, as floods could potentially destroy any functions built in areas close to the water. We want to use our technical knowledge to provide floating functions on water for these wet slums.

Just as you can download apps on your smartphone according to your changing needs, you can adjust functionality in a slum by adding functions with City Apps. These are floating developments based on standard sea-freight containers, and because of their flexibility and small size, they are suitable for installing and upgrading sanitation, housing, and communication.

Inhabitat: What advances in technology, design, or materials have helped push your architecture forward?

Koen: In Holland, we have always been close to maritime technology. It is very exciting to take these technologies that are meant for things like offshore oil industries and use them to create a floating habitat for animals, birds and underwater creatures like the Sea Tree does.

I think the Internet and 3D visualization tools have really pushed my architecture forward because in an industry as young as floating architecture, it is only the power of visualization that can show the impact of floating developments for the city of tomorrow. The fact that we can spread our ideas around the world and get feedback, response, and help because of the digital revolution is unbelievable. If I would have started twenty years ago I probably wouldn’t have reached more than half of Holland, and Holland isn’t that big.

My designs are what we call “readable architecture”—product-like solutions that ask for simple and clear details. Not every material is suitable for that, and over the last three years we discovered sustainable composites that suit the architectural expression I want, and are ideal for projects in salty environments that require low maintenance.

But the most important advantage in technology is logistics. The fact that we now can produce our floating houses and developments in different countries and assemble them on the water without affecting the environment makes it possible for us to rethink economical models for large-scale production.

Inhabitat: What are you most excited about right now in this field?

Koen: I am most excited about how global mobile assets will enable cities in developing countries to leapfrog to higher prosperity. These assets are large-scale floating developments that are being invested in by very rich countries like Qatar, Saudi Arabia, or Norway. These countries have so much money to invest that they cannot spend it all in their own country. Instead of investing only in wealthy world capitals, they’ll invest in flexible real estate, which can be leased to coastal cities.

It’ll start with functions like floating hotels and stadiums for cities that want to organize the Olympic Games but who cannot afford the investment. But it will rapidly evolve into an industry where cities that have been hit by climate change-related disasters can lease an entire set of functions like energy plants, hospitals, schools, and sanitation. Just like we do with our Floating City Apps for wet slums, there will be large-scale solutions to instantly upgrade cities and help communities recover. I see floating harbors and even small floating airports that’ll provide instant infrastructure to cities recovering from natural disasters.

The enormous financial capacity of these countries enables them to build global mobile assets up front on stock. So, imagine a safe floating location somewhere in Asia composed of completely functional urban components ready to be towed to any disaster area that appears. All the technology and money is already available—it’s only a matter of changing perception before floating developments are an essential part of the climate change reality that’s waiting for us. I say that not as a negative sentiment, because I believe that change will lead to innovation that will bring prosperity. The future is wet, the future is good!

Koen Olthuis’s Floating Krystall Hotel to Sparkle off the Coast of Norway

Inhabitat, Beverley Mitchell, August 2014

Koen Olthuis and Dutch Docklands have announced a new project: a five-star floating hotel off the coast of Norway named the Krystall. Reminiscent of their Maldives development the Greenstar, this cold-climate sister project will take the form of a six-pointed ice crystal. As with Dutch Docklands’ other floating structures the development will be low-impact, and it’s designed to “blend in with the ‘winter environment’ between the most beautiful fjords.”

The Krystall will float offshore from the northern city of Tromso, located within the Arctic Circle. Designed to be completely self-supporting and self-sustainable, the hotel will have a diameter of 120 meters, and facilities will include 86 guest rooms, conference rooms, and spa and wellness facilities. It’s also billed as a perfect spot for viewing the Northern Lights due to its glass roof.

The five-star luxury and spectacular nature of the project is aimed at attracting wealthy visitors from Japan, Russia and Europe. As Olthuis told CNN, “In the hotel, you’ll float through hallways lined with cool, futuristic blue shapes, recline by a fireplace faced in transparent bricks resembling ice blocks and sleep in rooms tricked out in minimalist, winter-themed designs.” But true to Olthuis’s green principles, the design is not just about the aesthetics. To be built in dry dock and then positioned in place, the hotel will not leave a lasting footprint on its location. “That’s the only way to bring a hotel to such a precious and beautiful marine environment,” he says.

Floating structures are a pragmatic design concern for the development company, as they ameliorate the risks to coastal properties associated with rising sea levels. As Olthuis explains, “We live in a dynamic world where static buildings do not bring us the needed flexibility. Building on water brings us new space for expansion, safety against floods and flexibility to adjust developments without demolition whenever needed.” The hotel is set to open in December 2016.

How Can We Waterproof Our Future

Inhabitat, Yuka Yoneda, Feb 2014

When the movie Waterworld premiered in 1995, people regarded the Kevin Costner flick as a fairly ridiculous post-apocalyptic science fiction film: Now, nearly two decades later, the tale’s premise of a world where nearly all land is submerged beneath the seas seems more like a prediction of what’s to come than a figment of a screenwriter’s imagination. With polar ice caps melting rapidly, the clear and present threat of rising tides is no longer something that can be pushed aside. According to current scientific estimates, the earth’s temperature will increase at least 4-5 °C by the end of this century, leading to a sea level rise of approximately 2-7 feet or more by 2100, which will submerge significant portions of many of the world’s major metropolitan areas, including New York, London, Shanghai and Mumbai. Since we’re facing some pretty catastrophic changes, some of the world’s best minds are working on solutions to prevent, or at the very least, minimize, the land loss and human habitat destruction that lies ahead. But between dams, water barriers and floating cities, it’s easy to get lost in the “flood” of different options for dealing with rising sea-levels. Bettery Magazine recently broke down our current situation and the various types of approaches which are being tried all around the world to deal with rising waters. Read Bettery’s full report for a better understanding of how we can waterproof our future.

Waterstudio.nl Proposes Floating City Apps To Aid Slums Affected By Rising Sea Levels

Inhabitat, Bridgette Meinhold, Nov 2012

Waterstudio.nl, the leader in floating architecture, is now working on helping slums cope with climate change and rising sea levels with a collection of floating functions called City Apps. Slums are tight on space and many have grown up along the water and are at risk for rising sea levels. Waterstudio.nl’s City Apps can provide critical infrastructure as needed. Whether the area needs additional safe housing, sewage treatment, more electricity or space to grow food, these modular and flexible units can serve as catalysts for change. The Netherlands-based studio was recently awarded the prestigious “Architecture & Sea Level Rise” Award 2012 from the Jacques Rougerie Foundation with their entry: App-grading Wet Slums.

Wet slums are slum communities that live in conjunction with the water and many occur around the world. The connection to the water also puts them at risk for climate change and rising sea levels. To aid these communities, Waterstudio.nl has been researching how they can put their know-how of floating architecture to good use. They’ve come up with a series of flexible, adaptable City Applications or City Apps that can aid these communities now and in the event of disaster. With little space available inside the slum, the nearby water provides open space in which to add critical infrastructure to the community.

The City Apps consist of four different types of floating infrastructure designs that can provide food, water, shelter and energy. A floating field can be used as a large community garden to grow food for consumption in the slum or produce food that can be sold in the city. Floating sewage stations can provide potable water for drinking and help process waste to improve hygiene. Floating buildings can be used for additional housing or used as schools, clinics or community centers. Finally floating photovoltaic systems generate energy for the community.

In conjunction with the design of the City Apps, Waterstudio.nl has been researching about 20 Wet Slums around the world and determining their characteristics. This fingerprinting of the slums will help leaders understand the needs of each community and more aptly be able to provide aid and support especially in the event of a disaster. Waterstudio.nl hopes to partner with more organizations to spread their research and help these communities. Their work was recently awarded the “Architecture & Sea Level Rise” Award 2012 from the Jacques Rougerie Foundation.
