Les Tit’B Libres is a group of young French artists living communally in handmade structures, such as this cob home with a reciprocal roof.

To build a reciprocal roof, we first install a temporary central pillar on which the first chevron is placed. The height of this pillar depends on the roof pitch.The following rafters are then placed to support the one on the other. The last chevron place above the penultimate and below the first one. They are then attached to each other and the central pillar is removed. If only one of the rafters breaks, the whole structure collapses.
