Moos De Hill 
Made up of a stack of two simple volumes, the Moos De Hill house’s triangular shape opens onto the Lyon landscape. Its surprising play of contrasts and mass are captivating, and its construction has enlivened the neighbourhood, which has followed its development with interest.

The balance of the building rests on a 23-tonne karst rock shaped by time. It supports the first floor and marks the starting point of the immense 18-metre cantilever that seems to defy the laws of physics. The floors have been lightened for greater structural inertia; rows of empty shells called U-Boots have been embedded in strips in the slabs. The intermediate floor is slightly raised by tie rods that suspend it from beams embedded in the roof. It is a complex, technical structure that brings us back to a human scale.

The general shape of the house was guided by the morphology of the site and the landscape. On the north side, the house is enclosed on the cut point of the triangle where the garage is located, close to the point of access. To the south, the façade is completely open to the landscape, bringing light into the living rooms on the ground floor and the bedrooms upstairs.

The deep overhangs provide effective protection against overheating in summer, while allowing the more horizontal winter sun to shine through more deeply. The secondary bedrooms, open to the west on the first floor, are protected from the horizontal rays at the end of the day by a mashrabiya made of white Ductal pebbles suspended from invisible steel cables that gently undulate in the breeze.

A glass roof brings light into the heart of the building.
The white concrete emphasises the formal simplicity of the construction.
Inside, the concrete walls are visible. The non-load-bearing partitions are differentiated and painted white. The built-in furniture and the kitchen are made from the same bamboo wood, textured in successive half-cylinders.
