With the walls in the living area at full height, it was time to raise the roof beams. All the timbers were eucalyptus trees sourced from a sustainably managed plantation on the ridge up behind the house, The trees were simply trimmed of branches and pealed of their bark before being put in place. The most challenging part of the process was raising the large tree that would become the ridge-beam over the living area.
After the ridge-beam was in place the rafters and battens went up fairly quickly. Any timbers that pas over or run along the top of the walls are tied down with metal rods that were imbedded into the walls as they were rammed. The tie-downs act to stop the roof from lifting during strong winds and tie the walls together using the timbers as a kind of bond-beam.
Tin on and looking like a house! The plan is to line the tin roofing with mats woven from papyrus to insulate from radiant heat from the sun and noise from the rain.
