The main frame of the roundhouse would have been made of upright timbers, which were interwoven with coppiced wood - usually hazel, oak, ash or pollarded willow - to make wattle walls. This was then covered with a daub made from clay, soil, straw and animal manure that would weatherproof the house. The roof was constructed from large timbers and densely thatched. All of the domestic life would have occurred within the roundhouse.
