VERNACULAR 1700 - Present

Cruck Houses

‘Crucks are pairs of curved timbers rising from ground level, meeting at the apex of the house and supporting the weight of the roof. ..Crucks were widely used in vernacular buildings in Wales, Scotland and western England, but not in the south or east of England. ‘
[F.H.A Aalen p.153 Atlas of the Irish Rural Landscape]
Cruck framed buildings are increasingly rare in Ireland.
