Building a Celtic Roundhouse
The walls of roundhouses were either dry stone filled in with clay and straw, or a ring of support poles weaved with wattling and plastered in daub, or a mixture of both stone and wattling as being built here (left). Wattle and daub is one of the oldest building techniques dating back to the Bronze Age and beyond. Wattling is a way to build walls by weaving long flexible sticks in and out of upright posts. Hazel, which is pliable and grows naturally long, is a good species to use for wattle. It is also the preferred wood used by straw bale builders to pin bales together. Daubing is the method used to weather proof the wattle with a mixture of clay, earth (sand), straw and manure. The upright poles are usually around 4-6 inches thick, straight with their ends charred in a fire (see bottom left) and buried about 8-12 inches deep.
