Double-Double Reciprocal Roof


To fill the large spaces between the Eucalyptus beams, we built another double reciprocal roof offset from the first using bamboo. This was easy as we already had the shape, pitch, and support of the wooden beams below. The bamboo beams are not yet connected to the wood, only to themselves. We will put in columns next, to the concrete bond beam, to raise the bamboo structure slightly and then we’ll weight down the bamboo to touch the eucalyptus. With the Bamboo structure slightly higher than the Eucalyptus structure, the cladding will create 12 shallow barrel arches, it should look a bit like a circus tent, or a hot air balloon, or a shell, we hope.

      Thanks Tom, we’re getting close, the concrete comes next, hopefully it will be as easy as the icing on the cake.
