The educational farm and ecomuseum's structure and cladding are made of wood. The use of this material is a reference to barns. Those two buildings are eclosed by a big massive concrete wall that constitutes the farm courtyard. It is lined by gabions filled with moss and climbing plants. On the contrary, the warhouse expresses an opening on the site: a fusion bewtween the ground and the sky. Its facade provokes a vibration imitating trees and nature made by different translucid, transparent and opaque layers of polycarbonate.
