Building Castell Henllys

Wales: The first roundhouse was reconstructed on the Castell Henllys site in the 1990s. The original buildings are beginning to deteriorate and are now being renewed, which gave us a good insight into the building methods.

A company that builds using timber frames has started to put in place the wooden structure of a new hut. Then the walls will be constructed using hazel rods woven through timber posts (the wattle) - see example above left. Once the reed-thatched roof has been added, the walls will be finished with dried mud (the daub). The guide told us that the circular structure is built around a central post. Once the structure is balanced  and self-supporting, roped and jointed together, the central post is sawn off up in the roof, to provide an open living area.

There's a great beauty in the roof structure, being at once organic and ingeniously engineered. The photo below is looking more or less directly up to the apex in the middle.

This is a more detailed view of the thatch overhang at the entrance, showing the timber and ropes.
