The existing bungalow comprises a one-storey building of the seventies. Almost one fourth of the floor area is taken by a garage that is hardly used. The owners ask for a modest extension in order to fulfill the needs of a growing family. Zoning laws allow the existing volume of 541m3 to be maximized to 1.000m3.We suggest conserving the existing volume, extending it with a one-storey box that is East-West oriented. The new volume is situated within the permitted building zone and lies parallel to the site border. A covered parking spot is planned at the front. At the back, part of the volume is subtracted to allow for a roofed terrace, sheltered from the harsh western wind. The main entrance to the house is situated in line with the extension.
