The standard dwelling in the Iron Age was a stoutly built round wooden hut with a conical thatched roof and a porch opening to the south-east.
Chysauster in Cornwall, inhabited from about 50 BC to AD 300, was built in a much more ancient tradition. The irregular, fetus-shaped houses with thick, stone-built walls were much more like the stone houses built in Neolithic Orkney hundreds of years earlier. The design was probably partly remembered from an earlier age, and partly a response to a windy, maritime environment.
At Jarlshof in Shetland, the communal memory linking the centuries is made visible. Jarlshof was first inhabited in the Neolithic and continued as a village through the Bronze Age and into the Iron Age, with interruptions when it was engulfed by sand.
Like the Jarlshof houses, the houses at Chysauster were in effect stoutly walled courtyards designed to keep out the wind, with rooms opening out of them. Once there were walled fields round Chysauster, the walls dating from the same time as the village. to an insane EU subsidy policy, these were plowed up some time ago to make a rocky landscape that is no use for arable or pasture, and its archeology has been destroyed too.
The brochs of Orkney, Shetland, and the Western Isles of Scotland represent a similar design approach—rooms ranged around a courtyard—but carried up into the air to make imposing towers. The finest is the Broch of Mousa, which has survived almost intact because of its inaccessibility on an uninhabited island off the east coast of Shetland. Built in the first century BC and inhabited until about AD 150, it soars 40 feet (10m) above the shore in a graceful drum shape. Timber ranges once lined the interior walls, with galleries at various levels, reached by stone staircases built within the thickness of the outer wall. There was a single door and no windows; it must have been very dark and dank inside.
The hearth was the centerpiece of every dwelling and it had the status of an altar in domestic cult. This custom may have had its roots in the Neolithic; the layout of the stone houses at Skara Brae in Orkney, with large central square hearths, treats the domestic fire almost theatrically.
The Laws of HywelDda supply inventories of the objects to be seen in a typical household in early medieval Celtic Britain. They include boilers, blankets, bolsters, coulters, fuel axes (axes for chopping firewood), broad axes, augers, gimlets, firedogs, sickles, baking griddles, trivets, pans, and sieves.
