Grade II listed barn conversion, near Launceston. The project involved the conversion of a single-storey, single-space barn to create an annexe to the farmhouse, with self-contained additional accommodation with full disabled accessibility. The building presented a number of issues, including the fact that as part of its structure was below ground level the issue of damp penetrating the the solid stone walls had to be considered. Also, as the building is quite narrow, a space saving solution for insulating the walls had to be adopted.
