• the four vertical walls having a height of at least 2.4 m and comprising at least two partial roofs attached to at least two of the four vertical walls, having a surface parallel to the base and extending over the space, the surface area of the at least two partial roofs being equal to at most 50% of a surface area corresponding to the rectangular section space,
• wherein a first wall of the four vertical walls is attached to a first partial roof of the at least two partial roofs, and a second wall of the four vertical walls is attached to a second partial roof of the at least two partial roofs, and the height of the second wall is greater than that of the first wall, the second wall being parallel to the first wall,
• wherein the first partial roof of the at least two partial roofs and the second partial roof of the at least two partial roofs do not overlap.
