Description

Trebullom House is a farmhouse that has been converted into a private house. It dates from the early 19th century and was extended in the late 20th century. The building is constructed of stone rubble and features a slate roof with hipped ends across the rear, as well as a lower slate roof with half hipped ends for an attached cottage at the back. There are stone rubble end stacks, some of which are partly slate hung.

The house has a double depth plan with the entrance located at the rear. The principal front faces the garden, with the two main rooms situated on this side and heated by end stacks. A service room is located at the rear right. The late 20th-century extension links a small originally detached one-room cottage to the main house.

The exterior of Trebullom House is two storeys high and features a symmetrical three-window garden front. This front includes dressed stone segmental arches and early 19th-century 16-pane hornless sash windows with crown glass and internal shutters, with three sashes on the ground floor and three directly above. A 20th-century door and window have been inserted into the left-hand side elevation. The interior has not been inspected.
