paris-based studio christian pottgiesser architecturespossibles (christian pottgiesser, pascale thomas pottgiesser) has sent us images of their recently completed project, ‘maison L’, a private residence for a six-person family. located half an hour’s drive west of paris, the roughly 5000 m2 plot of old trees called for a design that would leave the spacious grounds predominantly untouched.
general view
the project works with a pre-existing 18th century orangery, a conservatory-like building with a seven-meter high ceiling line on the northern part of the site. to disturb the ground as little as possible, ‘maison L’ extends 50 m to the north-west to line the boundary, resulting in a general ‘L’-shaped plan.
considering the natural topography of the site, the house is buried up to two meters below grade with a garden roof covering the ground storey. this main level remains largely open and connected, with varying degrees of privacy depending on the depth of the zone’s placement. five three-storied tower-like volumes puncture through the green roof to stand almost autonomously with the main level. positioned to frame a specific perspective of the site, each tower houses a dressing room, storage space, a mezzanine, bathroom and a bedroom.

though mainly underground, natural light is ensured to the main level through a stretching of the interstitial space between the tower’s structure and the garden roof. the steel-framed gazing blurs the boundary between indoors and outdoors, directly connecting the inhabitants with the outdoor elements.

to further highlight the presence of the towers, the exterior facade of the main level is lined with a curved stone wall which blends the structure into the site. elements of this stone wall is repeated further into the plot, becoming retaining walls for surrounding pathways.
