A house that grows in length, on a plane alone and without corridors or lobbies. A series of functions arranged in a sequence. Completely permeable to the meadow and the forest. More closed and protected from the cold to the north. The design of a single family dwelling uni-floor made of wood and the construction of a wall counter-earth that helps to consolidate the backfill on the northern boundary of the lot in addition to the regular drainage of rainwater. It is a topography binding because of the altitude difference from the entrance at the border towards the valley, more than 7.50 meters in depression. The need to continue the containment walls is born from the instability of the soil analyzed. since then a clay soil is no need to dry it to make sure that the pole foundations of the house are working properly and can not slip into the valley, and these walls are also useful for drainage of rainwater. On the walls of the containment will be done growing ivy to get some "natural" and completely hide the concrete which will be realized. Ivy will grow on wire mesh.
