Architecture, urban planning and research in, on and next to water
A Visionary Where The Art Of Construction And Water Come Together

A visionary where the art of construction and water come together

Water enjoyment, Koen Olthuis, March 2013

Rising sea levels resulting from climate change present many nations with serious problems, with disastrous floods posing an increasing threat.
Where will people go when there is no land left?

When your country is threatened by rising seas and land is literally eaten away by the sea you have two options. Either you will move towards higher land or you change perceptions and
look at all the space on water as an opportunity to build upon and start utilising it. This sounds unrealistic but the Republic of Maldives is already planning for this geographic change. This nation exists of 1200 islands spread out over 700 kilometres in the Indian Ocean. With the highest grounds not more than 1.60 meters above water this country is the first to suffer from rising sea levels. Even a relatively small water rise of 30 cm in 60 years, it will mean a big change for the Maldivians. There are voices within the government who believe that buying new land on the continents would be the best way forward. This would however mean the loss of local cultural roots and identity.We believe that there is another option. Making floating land.
Large floating landscapes which would look the same as a normal land. In a way not so different from landfill, but more sustainable. These new islands would have beaches, houses,
trees and more green. We think that this is not a process over a few years but of a period of few decades where our floating donor land would be slowly over taken by vegetation and fauna
of the existing sinking islands. To kick-start this process Dutch Docklands is developing the first large scale projects like the floating private islands Amillarah and the floating golf course of 500,000 m2. These projects show the feasibility as well as the possibilities of a future with rising seas.

You see the interface between architecture and water not as the point where two separate entities simply come together, but where they connect and shape each other What is the vision behind this idea?

For a long time we have thought that living on land or living on water are two separate worlds. The border was clear and even rules and regulations change by crossing the waterline. Today
we see that water is a new available space to expand our cities and solve several problems caused by climate change and urbanisation. No longer is there a collision of two worlds but an
integration of maritime and land based functions. We believe in hybrid solutions where the boundary between land and water is blurred. This means that if you are driving your car from the mainland towards floating islands you will not see or notice any difference. The only thing different is the foundation under the surface is made of another technology.
Next to the enlargement of building space there is another opportunity when we start using water for city expansion. Water provides flexibility. Theoretically, functions on water are
no longer doomed to stay on a fixed location during their total technical lifespan. These floating developments can easily be moved because of the simple mooring system. This means that
we can move functions throughout the city when needed. No longer we have to demolish buildings when they are out of use but we can re-use or resell them to other locations. Exactly
the same as happens with second hand cars. By this we create a city that provides enough flexibility to react instantly to the changing need of our dynamic community. Often we see that
buildings or functions which we thought were perfect ten years ago are no longer fulfilling our needs today. I do not believe in totally floating cities but in hybrid ones that use water territory for an extra place to expand and to create flexibility that fits our constantly changing demands. Your projects “Cruise Terminals” and “Het Nieuwe Water” in the Netherlands and with other projects in Dubai, you are entering “new territory” in every sense. What are the features of these new “architecture / water interfaces”? The new territories we enter provide us with new challenges. But it is not the technology that is holding back the use of water but our perception. In order to let water be the essential part of the metamorphosis to the cities of tomorrow we should show authorities and developers the opportunities that water can provide. Water provides next to the flexibility I just mentioned also some sustainability and ecological advantages. Floating solar energy fields which spread out like large blankets over the water, water-cooled floating buildings and green floating habitats to composite the lack of open green territory for little animals on land in growing metropolis.

Your innovative designs of floating structures pave the way to a future where whole cities can exist and grow on top of the water. Will this approach result in protection against flooding
and increase responsible use of dwindling water supplies?

Our designs are part of a new approach against urban flooding. The oast has taught us that defensive solutions like higher levies and canalization of rivers are not sufficient any more. We think they must be in close combination with more offensive concepts that live with nature and the water. Floating and amphibious solutions are not threatened by floods and can provide safe heavens during times of disaster for many inhabitants of the old land based functions. It is not only land or only water developments but the cooperation of both that will lead to safer waterfront cities in the future.

City Apps by waterstudio.nl – sanitation solutions in slums for the poorest of the poor

As a pioneer of “floating architecture”, you develop solutions for sanitation facilities in slums. Under the project name “City Apps”, the aim is to create desperately needed solutions for the poorest of the poor. What has been your contribution to this altruistic project idea and how far along is the implementation?

In 2011 I started research together with UNESCO-IHE in
Delft to see if water based functions could help slums located at the waterfront in growing development cities to upgrade their prosperity.

Slums in coastal regions – such as the Korail slum in Bangladesh – are being upgraded with floating sanitation components. How does that work?

The idea is that the lack of space and the resistance to invest in these slums because of the uncertainty of eviction disturbs any possible upgrade of conditions. By using space on water we
could introduce so called city apps to these slums. City apps are floating products that provide the most essential functions like floating sanitation, floating shelter and floating energy
productions and communication. These functions are built in containers in Europe and shipped over to these slums. In the slums we build the floating foundation and place the containers
on top. In case of any eviction or change in needs these city apps can be re-used or resold to other locations. These city apps hold their value and should be part of an investment
program to upgrade these slums towards the normal local city standards. These investments will be done by European influential brands which are dominant in their field of expertise
and want to use their expertise to make a difference. Again it should not be a matter of donating but investing in a small scaled business case to create commitment and interaction
with local users and local micro businesses.

After research and a fieldtrip we have chosen Korail a wet slum in Dhaka Bangladesh to be the first location where we want to upgrade prosperity.

Your award-winning idea therefore requires a team of different companies for the development, the components, installation work and project management. What local and external partners have you already secured for this project?

What contribution has been made, for example, by Grohe AG, a leading international company for sanitation components? One of the functions is a floating washroom and toilets together
with a filter system for the black water. GROHE is a typical market leader which has gathered innovations and products for the western high end market. This knowledge is very vital for
our sanitation app. GROHE will provide both products and knowledge for the implementation of the first city app in Korail.
