THE FLOATING DUTCHMAN

In the tradition of his water-taming nation, Dutchman Koen Olthuis designs floating islands to dwell and live on – not least because climate change calls for new solutions in architecture.

A vacation doesn’t get more wonderful than this: a white sandy beach, a green-blue, glistening sea and an exotic underwater world to thrill any snorkeling enthusiast. All you have to do to explore it is jump into the Indian Ocean from your personal jetty, because the elegant vacation villa where you’re staying is floating on the water. In a Maldivian lagoon, this dream is currently becoming a reality as the construction of 185 floating vacation homes is currently underway. They’re arranged in the shape of a giant flower on the water. Hence the name of the project: Ocean Flower.

It was designed by Koen Olthuis, a Dutch architect who is considered a pioneer of what is called Aqua Architecture: “I build exclusively on the water,” says the 44-year-old with a strawberry-blonde mop of curly hair. His buildings are made to withstand floods and climate change because everything Olthuis designs can adapt to the level of the sea. It is not by accident that his office in Rijswijk near The Hague bears the name waterstudio.nl.

Bracing for climate change, without leaving a trace

In order to make such bold projects as the Ocean Flower a reality, Olthuis partnered with a fellow Dutchman, project developer Paul van de Camp, to found the company Dutch Docklands. It buys water properties all over the world to use them as building sites. This opens up completely new perspectives – not only for densely populated cities or countries where building sites are in short supply and hence, expensive: “It also helps residents protect themselves from the consequences of climate change.”

There is a reason Dutch Docklands launched its first project in the Maldives. It’s not just to cater to the recreational interests of spoiled tourists: The 300,000 inhabitants of the island nation will soon literally be up to their necks in water, because 80 percent of the Maldives are located barely a metre above sea level. The government had already announced plans to buy to land elsewhere in order to survive. Until Olthuis and van de Camp assured them that this was quite unnecessary: “We made the President of the Maldives understand that climate refugees can be pioneers of climate management,” said Olthuis. They understood immediately.

The Ocean Flower is just the beginning: Four more lagoons with floating vacation lodges are to follow, as well as a floating conference centre and one of the world’s most spectacular golf courses that will spread over several man-made islands to be connected by underwater glass tunnels.

And all this can be done without leaving a trace in nature or inflicting any damage, for Dutch Docklands is committed to what it calls the scarless approach: “Our units can float anywhere on the water for 200 years, yet if the area is needed for some other purpose, they can just be hauled away,” Olthuis explains. They will be gone without a trace.

The Dutch know how to live with the water

It isn’t surprising that the pioneers of Aqua Architecture are Dutch: Like no other people, the nation at the mouth of the Rhine River has spent centuries learning to tame the water or to keep it in check with dikes, dams and levees. As the proverb goes: “God created the world – and the Dutch the Netherlands.”

Whether it is in New Orleans or in Bangladesh: The expertise of Dutch hydraulic engineers and architects is in high demand throughout the world – today more so than ever, thanks to climate change, which brings swelling rivers, rising sea levels and more catastrophic floods around the globe.

The Dutch have long recognized that building ever higher dams won’t be enough. Therefore, the former nemesis is instead given more space: Polders are being flooded, retention basins are being built, tributaries being carved out and filled-up canals dug free again.

The old seafaring nation now has even less residential land available. Yet the Dutch discovered that the flooded polders and artificial water basins offer more benefits than just a controlled channeling of excess water.

Trend and challenge of generation climate change

As a consequence, aqua living has since become a trend in the Netherlands; all over the country, people reside in what is called waterwoningen. Their foundation consists of a concrete tub filled with Styrofoam, which is considered unsinkable. To keep them in place, they are moored to poles with rings so they can easily adapt to rising sea levels. Electricity and water lines are connected via hoses and cables.

Olthuis has designed countless waterwoningen: transparent villas sitting elegantly on the water, such as in Aalsmeer, Zwolle, Leiden or Amsterdam, which received an entire floating neighborhood in 2012, the steigereiland. In Antwerp, Olthuis designed a floating boulevard on the Scheldt, in Paris he created a restaurant on the Seine. And in a polder between The Hague and Delft, he wants to build de Citadel, Europe’s first floating apartment complex on a foundation of 140 by 90 metres. “Technologically speaking, all of this is easy to do,” he stresses.

The technology developed and patented by Olthuis virtually eliminates size limits on foundations for waterwoningen. In other words, the foundation can be a platform large enough to accommodate entire blocks of houses, complete with yards and parking garages: “The larger an object, the more stable it is on the water,” the architect explains.

Olthuis is therefore convinced: The city of the future consists of floating platforms that can be moved around like floes of ice. “It will evolve one step at a time,” the bold Dutchman predicts: The next fifteen years will see churches, schools and sports fields move out onto the water, then in 50 years, we will have platforms as large as 200 by 200 metres, with houses, roads and parks – until a century from now, the city of the future will be a reality: a flexible delta-metropolis of floating elements. For Olthuis, this new type of urban design, this new flexibility is “the great challenge for the architects of the climate change generation.”

1st Scientific paper on researching wetslums was published

Slum Upgrading: Assessing the Importance of Location A plea for a spatial approach as an integral component; view online (free till Nov 1st)

Abstract

The world population is growing rapidly and much of that growth is happening in urban areas. In developing countries, this process is often accompanied by the formation and expansion of slums. A variety of slum upgrading projects have been implemented to improve the living conditions of slum dwellers however a wide study to investigate the objectives of slum upgrading projects highlighted that environmental features were of low priority compared to basic services and infrastructure. The paper deduces this to be a result of the dominance of UN’s household-based definition of slums which lacks emphasis on the locational aspects. An aerial analysis of slums located near waterbodies emphasised the slums’ dynamic nature brought about by location and therefore the importance of location itself. Taking cue from this, the paper recommends upgrading projects to be more location-specific that offer flexible yet customised solutions that build upon local knowledge to account for the dynamic and diverse nature of slums. Another inference from the study was that for various reasons – one of which is hazardous location – slums are perceived to be temporary and as a result, there is low incentive to invest in slums. Such a perception prohibits slum upgrading and pushes them into a negative spiral. Concluding that slums are, however, permanent features in the urban landscape, the paper recommends a change in perception and urges practitioners to accept this permanent nature of slums. The focus and findings of this paper are relevant in context of the Habitat III Conference in 2016 which has as its focus the ‘New Urban Agenda’ that recognises the ever-changing dynamics of human civilization and aims to bring together diverse urban actors to review urban and housing policies.

Podcast: Maldives’ Floating City?

The Seasteading Institute, Joe Quirk, Nov 2015

Interview of Joe Quirk from the Seasteading Institute with Koen Olthuis about  Maldives’ floating cities.

Podcast: Maldives’ Floating City? Koen Olthuis of Waterstudio

Podcast: Play in new window

What if a nation sinking below sea level became the innovation hub for floating cities?
What if you could float the infrastructure of Holland to the slums of Bangladesh?
What if the future of floating cities is in 3D printed technology?

Dutch architect Koen Olthuis is the co-author of Float! Building on Water to Combat Urban Congestion and Climate Change with David Keuning. Koen founded Waterstudio which designs many components of floating cities, including schools, golf courses, hotels, and even stadiums, and he co-founded Dutch Docklands which plans gorgeous projects for the Maldives.  In 2007, Koen was chosen at Time Magazine‘s “most influential people of the year,” and the French magazine Terra Eco chose Koen in 2011 as one of the 100 greenest persons who will change the the world.

Koen Olthuis initiated a project to transform shipping containers into Floating City Apps to upgrade living conditions in coastal slums by providing “plug-and-play” schools, kitchens, health centers, internet cafes, and water purification units.

Should seasteads establish political independence first, and then change the world? Or should floating cities set humanitarian examples, win hearts and minds, and then seek independence? Koen and I discuss the strategies and agree to partner on a shared goal.

I hope you enjoy this discussion as much as I did. And if you subscribe to podcasts on iTunes, you can find this podcast and all of our other podcasts on our iTunes page.

Floating City Apps: A Lifeline for Slums

By Carol Matlack
Bloomberg Businessweek
September.2015

 

Dutch architecture firm Waterstudio uses shipping containers to build structures that benefit people living in flood-ravaged shantytowns.

Firm: Waterstudio
Location: Rijswijk, Netherlands
Total Cost: $28,000

More than 600 million people worldwide live in shantytowns that suffer chronic flooding. Because these settlements are often illegal, entrepreneurs and community groups can’t get the building permits, insurance, and bank loans to open grocery stores, health clinics, and other essential establishments.
Dutch architect Koen Olthuis thinks he has a solution: His Floating City Apps are structures built from shipping containers that can be docked alongside waterfront slums. The first, set to be deployed in Dhaka, Bangladesh, this fall, will be outfitted with 20 computer workstations. It will be used as a classroom in the daytime and as an Internet café in the evening. Unesco and local non-profit are subsidizing construction. Because the units are vessels, they will qualify for insurance and private financing, which may also make them attractive options for local business.
Olthuis’s firm, Waterstudio, specializes in waterborne architecture and building floating resort in Maldives. He wants to put some of that know-how to work for the benefit of the poor. “The architecture is simple”, he says. “But you need to have a business model”.

This demonstration unit in the Netherlands is outfitted as an education and communications center, with 20 touchscreen workstations.

These Floating Sea Trees Could Bring Wildlife Back to Big Cities

By Tailor Hill
Takepart
August.2015

The offshore structures would provide habitat for animals, birds, and fish.

Taylor Hill is an associate editor at TakePart covering environment and wildlife.

In the world’s biggest cities, it’s hard enough for humans to find a little elbow room—now think about carving out habitat for wildlife in places like Manhattan.

Dutch architect Koen Olthuis thinks he has the design that can extend urban sprawl into city waterways—but instead of floating high-rises offshore, he envisions wildlife oases within city limits.

Called Sea Trees, the steel structures are based on existing offshore oil platforms. Anchored to the ocean or river floor, Sea Tree pillars would extend above and below the water surface, providing “layered” habitats—almost like the floors of a skyscraper—for flora and fauna.

“Oil companies have used these floating storage towers for years, we only gave them a new shape and function,” Olthuis said in a statement.

Olthuis, head architect at Waterstudio, thinks Sea Trees could bring animals back to areas taken over by humans, helping to stem falling wildlife populations.

“It is becoming evermore difficult to allot an appropriate amount of land for the conservation of wildlife habitats within city limits,” said Olthuis. “Sea Tree would provide the ideal environment for a multitude of species, not to mention a significant reduction in CO2 emissions.”

Rivers, oceans, lakes, and harbors could all be potential locations for Sea Trees, giving a home to birds, bats, and bees above the waterline while providing habitat for fish, crustaceans, and even coral reefs below the surface.

Waterstudio imagines a forest of Sea Trees built off the Manhattan and Brooklyn waterfront; it could provide living spaces for wildlife along some of the most expensive stretches of real estate in the United States.

Olthuis designed Sea Trees to be inaccessible to humans.

“Water is, of course, a perfect way to keep people away,” Olthuis said. “In the end, it has become a vertical hangout for wildlife.”

While the concept is still in the development phase, Waterstudio thinks Sea Trees could be built today because much of the technology exists. The architecture firm estimates each Sea Tree would cost about $1.2 million, depending on the water depth and construction materials used.

“Large oil companies will have the opportunity to give back by using their own intellectual property and resources to donate Sea Trees to a community in need, showing their concern and interest in preserving the distressed wildlife,” Olthuis said.
