| Notes: | |
| A piggery was usually a small lean-to attached to the gable end of a building. The stable, cow house or byre and the calf house were often in one building separated by wooden partitions or low walls of stone. Barns could be separate buildings or they could be located on an upper floor above a byre, for example. Workshops and sheds were often part of another building, rather than a separate building. Coach houses and dairies were usually separate buildings. |
