Two types predominated, the beehive, circular with conical roof, and the lecturn or lean to, rectangular in plan, and usually with a mono-pitched roof. There were also many individual architectural solutions, often associated with designed landscapes, and usually very well detailed. Pigeon recipes abounded in the 17th and 18th centuries but once fresh meat became available all year round, the buildings became obsolete, apart from circumstances where the birds were decorative. Many are now ruinous, some have found new uses, one at Knapp near Dundee is now a house - Doocot Cottage.
Glover - the open cupola which frequently sit on top of doocots, allowing access and providing a place for the birds to sit and preen.
Potence - rotating ladder providing access to nesting boxes in circular plan doocots.
Rat or vermin courses - a projecting course of masonry, often stone slates, preventing rats gaining access to the nesting boxes.
