The model house: the Lighthouse has been constructed in 1999. After a promotional tour through the Netherlands (Leeuwarden, Amsterdam) the social housing organisation Rentre Wonen in Deventer bought the house and located it at the Holterkolk in Deventer 2006. A water house is floating on the water. In contrary to traditional living boats that are more container like, the water house has all the aspects of a house. The ‘Lighthouse’ is the model house based on a Canadian concept.
The Deventer “Lighthouse” has a platform of 7,5 x 9,0 m and a living surface of 180 m² and contains approximately 480 m³. The dimensions are flexible, but at least a length of 6 meters is necessary. A water house can float up and down, depending on the water level. Flexible cables and tubes and floating paths connect them with the shore.
Just as with ordinary houses, prices can differ a lot. At average, the costs of a Water House are +10% compared to an ordinary house. In the Netherlands people would like to pay more for a house next to the water.
Objectives and beneficiaries
People living in areas subjected to floods.
Expected results and benefits for climate change adaptation and mitigation
Floating houses have a better average temperature. Combination with heat exchange and cooling will be possible (especially at retention basins).
Replicability potential of the practice
At least 150 cm water depth is needed.
