Getting there with the roof at Dudsbury Guide camp. the original building was constructed by the guides with guidance from another builder. Unfortunately it fell down soon after as the roof was under engineered and the pitch too low. So much work went into the build that we felt we wanted to retain the walls. The roof is self supporting with an internal chestnut frame . The walls can be replaced at a later date if required. I also used as much of the old straw thatch at the top of the roof which likewise will need to ultimately be replaced and reduced the materials cost significantly. Not happy with the existing doors would like to do something with them when their budget allows.
