‘Maison L’ is the extension of an orangery of the late 18th century, inhabited by a six person family, on a small hill less than half an hour’s drive west from Paris city center. The organic and jaggy composition of the complex is interrupted by five three-storied tower-like volumes, stamping through the garden roof and providing a clear view until “La Défense”.
Here is what the architects explain:
“The provisionally installed internals in the existing building of the nineteenseventies, meant for optimizing the use of square meters, will be dismantled. By this, the former seven-meter high ceilings of the original orangery volume becomes apparent again. Local specific site requirements allow only one single building with a gabled or hipped roof. Therefore only an annexe type of building is possible. Furthermore the maximum height of a construction is restricted to eight meters.”
“Without a specific geometry the roughly 50m long ground floor of the extension opens up from the north-western side of the orangery. Due to the stringent height limitations, the ground floor remains up to two meters below the original ground level. The whole flank of the building towards the boundary of the plot is covered with soil which is continued on top of the 7% inclined roof. On the opposite side, along the south-eastern facade emerges a complex topography between the house and its landscape. Carved towards every entrance in the glazing the river-bed-shaped, undulating terrain distorts to ensure an efficient access and exit.”
“The private sector, shared by the six inhabitants – four children and two parents – is fragmented into four different elements. Each commands a certain part of the ground floor which gradually develops into a more and more private zone, without doors, communicating with the other family members.
The local building code allows however, in exceptional cases flat roofs, as long as they do not exceed 25m2 each. Thus five three-storied tower-like volumes were implemented, stamping through the garden roof. Glazings around each “tower” provide natural lighting and an intriguing succession of perspectives between above and below, inside and outside. In each private tower are located at the ground level, a dressing room and storage space, the mezzanine, a bathroom and, finally, in the second floor, a bedroom. The slightly bigger tower for the parents has a rooftop garden from where one has a clear view to “La Défense”, the business district of the modern Paris with its sky scrapers.”
