This “water-breaking” new project was designed by Koen Olthuis of Waterstudio, and developed by ONW OPP/BNG in the Netherlands, and will use 25% less energy than a conventional building on land thanks to the use of water cooling techniques.
Olthuis is responsible for a number of floating residences around the world and he thinks that we should stop trying to contain water and learn to live with it. The New Water and the Citadel projects are an attempt to embrace water in the Netherlands, which is almost completely composed of wetlands.
The Citadel will be the first floating apartment complex, although there are plenty of floating homes out there. Built on top of of a floating foundation of heavy concrete caisson, the Citadel will house 60 luxury apartments, a car park, a floating road to access the complex as well as boat docks. With so many units built into such a small area, the housing complex will achieve a density of 30 units per acre of water, leaving more open water surrounding the structure. Each unit will have its own garden terrace as well as a view of the lake.
