Trevalga Farmhouse, Garden Walls to Front and Outbuilding Adjoining on Right Hand Gable End

Trevalga Farmhouse, along with its garden walls to the front and an outbuilding adjoining the right-hand gable end, likely has origins dating back to the late 16th or early 17th century, with some remodeling occurring in the 19th and 20th centuries. The building is constructed of slate stone rubble and features a slate roof with gable ends, as well as a parallel range at the rear.

The original layout of the farmhouse is uncertain, but it appears to consist of two rooms and a cross passage. There is a small room on the left and a larger room on the right, both of which are heated by gable end stacks. A blocked opening leads to the late 18th-century outbuilding that is attached to the right-hand gable end. In the mid-19th century, a second parallel range was added to the rear, creating a double-depth plan. Churchtown Farmhouse was added to the left-hand gable end in the early to mid-19th century.

The farmhouse is two storeys high and has a regular four-window front. To the left of the wide plank door is a two-light horizontally sliding sash window, while to the right is a 20th-century two-light casement window with glazing bars. The first floor features three horizontally sliding sash windows and a 20th-century two-light casement window on the right.

Inside, the farmhouse has 19th and 20th-century plastered ceilings and joinery, although the roof structure has not been inspected. The garden in front of the house is enclosed by a wall made of slate-stone rubble. The single-storey outbuilding on the right-hand gable end is also constructed of stone rubble and has a lower rag slate roof with a hipped end on the right. The interior of the outbuilding has not been inspected.
