• Structure means a framework of assembled beams or a wall element or wall, solid or not, located inside or outside, that this frame or this element is vertical, horizontal or inclined. This is, for example, a partition wall, a load-bearing wall or a wall holding a slope. Structure also refers to the roof structure of a building.
