Netherland based Waterstudio have revealed its plans to construct world’s first floating apartment complex in 2014. The citadel will have 60 luxury apartments made from 180 modular units that will be arranged around a central courtyard and topped with green roofs. The main deck will consist of a floating, heavy concrete base measuring 240 x 420 x 9 feet that will support the lightweight apartments and a parking lot. Each unit will be wrapped in aluminum and topped with a green roof.
A bridge will connect the Citadel to the mainland and allow access for emergency and maintenance vehicles. Once water is reintroduced to the polder, the entire complex will float atop six feet of water. The overall design is estimated to make the apartments 25% more energy-efficient than developments on land.
