The project started with a wish from the client to create more space for the living floor of their house. The 1,5 meter level difference between the living room and the garden, which was at first seen as a constraint, became a source of inspiration to create a large room at the floor level of the garden but at the ceiling level of the living floor, integrating both spaces, but keeping them separate at the same time. This process resulted in a volume of 7/5/4 meters totally open to the garden with a fully openable accordion door and offering the living floor a balcony relation to the new space.
