The dominant building form in Iron Age Britain was the circular house. Contrary to popular belief these were not crude huts. These imposing structures were typically about 6 m in diameter, built from round-sectioned posts set into the ground at irregular intervals (Cunliffe 1978: 174-8). The posts supported the roof, but the eaves were taken beyond the ring that they formed to an insubstantial wall near where the eaves reached the ground. The space inside these buildings was therefore separated into a high-roofed central area and a lower area between the ring of posts and the outer wall. There is little other evidence for any internal divisions of space. In later houses posts were generally larger and more regularly spaced, and substantial porches were used to provide imposing entrances.
