The sculptural form of this extension is a nice contrast with the minimalexpression of the 1950’s house. The shape of the extension and the position of it's windows are carefully related to the interior functions. The skylight in the highest point provides extra daylight to flood the kitchen desk.The stretched window in the back facade provides a panoramic view intothe garden. The extension is built with sustainable materials and techniques. The prefab wooden walls are insulated with recycled paper scraps, which results in an insulationvalue that is twice as high as the current regulations prescribe.The cladding is made of platonised wood, of which the frontside iscarbonised using fire. This carbon layer gives the extension a deep black glow and simultaneously acts as a protective layer for the wood, resulting in a completely maintenance free facade. All construction elements are prefabricated and constructed at site, resulting in a total building time of 8 weeks. After the cellar and foundations were cast in concrete, the wooden extension got placed in one working day.
