Our first attempts at a slate wall, using a cob mix as mortar, have turned out rather well. This will act as a damp proof course for the strawbale wall above. Evie has laid out the lower course for the next section – below – and with any luck we’ll get another couple of sections built on Monday with the other volunteers..

Although our frame is hexagonal, we are gently curving the wall, so that we do end up with a roughly circular building. The frame will be built into the wall, and so will only be visible from the inside.
