Text description provided by the architects. This project was a geometrical challenge for the agency. The objective was to build a detached house for a family with two children and a dog in an area of suburban housing in Cachan (south of Paris), on one of the town’s last few buildable plots. The site presented a few constraints due to its irregular qua­drilateral shape; it was also bordered by a street, a path and a car park. The rules on non-constructible strips around buildings imposed a restriction of 43 m² of triangular ground floor space, and the house could only reach a maximum height of three floors.

Its maximum potential volume would give it a slender aspect that would make it look like a turret. The choice of a prismatic shape enabled us not to disrupt any existing perspectives as we did our utmost to maximise volume within this constricted space.

As it required a lot of space, vertical circulation was a challenge. We optimised it by placing it in the middle of the building and creating semi-level floors staggered in-between the main floors. This strategy enabled us to avoid any unnecessary landings and made the ceiling height in the living room very ge­nerous. The entire floor surface thus came to 85 m².

The structure of the house developed natural­ly around the staircase leading to a south-fa­cing terrace that we made accessible via a sky­light, designed to let a lot of light shine through to the centre of the house. When open in the summer, it would also make the house cooler by convection.

The structure of the house itself, made out of a pre­made wood frame, was held by Techno Pieux au­gered piles. Upon their arrival on site, the precast components were assembled by crane. This strate­gy made it possible to have a dry building site that was finished quickly. The exterior of the house was made of pre-greyed wood cladding sheets with varying orientations so as to reflect the diffe­rent inhabited spaces within the house, thus mani­festing the differences between floors in the facade.

The staircase was made of five completely distinct flights, and each linked landing faced a different direc­tion. This staircase was built by the digital carpentry workshop Super Cube, based in the WoMa Fab Lab. Thanks to their digital production tools, the crafts­people were able to precisely cut the components that were then transported to the site for their assembly. This also enabled us to make an elegant variable-iner­tia guardrail, making structural performance optimal and ensuring economical use of wood resources.

The Facet project thus demonstrates the bene­fits of using local economical solutions that re­duce building time and offer bespoke results. It also shows how architectural richness can be borne out of rare spatial and geometrical constraints.
