Luxembourg City-based studio Metaform has designed these Two Row Houses. Completed in 2010, the two contemporary residences are located in the village of Goeblange, in southern Luxembourg. The house is flooded with these skylights that are beaming from underneath in the evening and consequently avoids the use of prominent luminaries. A large glass aperture (10x3m) characterizes the interest brought to the outside light and landscape and tries to remove the physical boundaries of the house. The proximity and the orientation of the dock of water reflects the rays of sun onto the walls and ceiling of the central space, which is commonly used throughout the day. The construction regulations, impose a double pitched roof, was the source of reflection for the fifth facade; the roof deck. The idea to cover the facade with the same fiber-cement panels that reinforces the monolithic facade of the house and also raises the question of the relevance of a pitched roof that is too often imposed by the irregular construction regulations. The same treatment reduces or even erases the boundaries between the vertical surface (facade) and the inclined surface (roof).
