Designed by CCM2 Architectes in 2012, L House is a private residence located in Fossambault-sur-le-Lac, Quebec, Canada. The construction made of prefabricated parts help to reduce disturbances and construction site pollutants, while providing to the residence a quality of construction above standards. The material selection has been done to assure the integration of the contemporary L-House to the natural environment and to the neighboring houses. The master bedroom and its balcony projection overlook a section of the patio which spreads along the residence, defining two living spaces according to the needs. The guesthouse offers a lighten rest area. The architectural concept is defined by a contemporary reinterpretation of the vernacular architecture of Quebec’s summer cottages, especially neighboring houses. On the first floor, the family living area is filled with great luminosity. On the second floor, a library, a large washroom, the bedrooms and two balconies provide the owner with a great view over the St.Joseph lake. The fragmentation of the main volume, in projection and recessed, maximizes interior and exterior living spaces while minimizing the building’s presence on the site.
