Ruins of Trehane House and Garden Wall Adjoining to East

The ruins of Trehane House, dating from 1703, are preserved as a garden feature. The initials WIC for Williams impaling Courtney can be found on a lead rainwater head that has been reused on the former coach house. The house was gutted by fire in 1946 and is now roofless, with only the walls remaining. The structure is built of red brick in both English and Flemish bonds, with Pentewan stone dressings. Originally, it had a double depth plan with a central courtyard and stood two storeys high, featuring seven-window fronts on the north, south, and east sides. The principal east front includes an ovolo moulded plinth, a central doorway, and flat Pentewan stone arches over window openings that lack frames. There are moulded Pentewan stone sills and a plain band at the first-floor level, along with four giant brick pilasters. One original sash window survives at the rear, showcasing thick ovolo moulded glazing bars. Two axial walls remain, complete with tall brick stacks. Additionally, there is a contemporary brick wall at the northeast corner, which forms the north side of the east garden, with brick courses laid to follow the gentle slope of the land on the east side.
