The “Maison Seven” is an upscale house made entirely made of rough concrete and steel. It is located in the heart of Lyon in a residential neighbourhood. Its simple shape required long hours of design from Pierre MINASSIAN. The many architectural details, in particular its metal assemblies, are very complex and make this house a unique contemporary work in the city centre. The large windows offer a dialogue between the interior of the house and the garden with his long pool corridor.
