definitionThe basic characteristic of floating buildings is that they are not supported by a firm foundation, but float on water. Traditional foundations are therefore not required. The position of a floating building is permanently fixed in a horizontal direction, while it can flexibly follow vertical variations in water level. The base of a floating home consists of a floating mechanism that secures the building’s buoyancy. The bottom level of the entire construction should be at least 1 meter from the water bottom in order to maintain favourable water quality conditions. It is essential that a floating building never touches firm ground, because the construction is not designed for such conditions. The floating mechanism that is positioned at the basis of the floating structure can consist of high-density expanded poly-styrene or a hollow, concrete structure. Hollow space can be used for storage of light goods. Floating homes can have terraces that can be regarded as a small-scale version of traditional gardens. Infrastructure connections to floating buildings should be designed so at to be able flexibly cope with expected water level variations.

Co-benefits and impactsFloating buildings have environmental benefits such as unsusceptibility to changes in sea level, and minimisation of disturbance to the ecology of the harbour or seabed. They can be built off-site and then towed into location, minimising disturbance to the build site. If the building is decommissioned, it can be relocated elsewhere.
