Trevilvas Farmhouse with Garden Wall, Iron Railings and Gate to South

Trevilvas Farmhouse is a farmhouse with a garden wall, iron railings, and a gate located to the south. It dates from the 17th century, with additions and alterations made in the 18th and 19th centuries. The building is constructed from shale rubble and granite, featuring scantle slate roofs and brick gable chimneys. It has an L-shaped plan, with an additional 18th and 19th-century wing at an angle under a double span roof to the east and a porch in the northeast angle.

The farmhouse is two storeys high and has a three-window south front. The central entrance features a six-panel door with a lattice porch, and there are wide window openings with timber lintels. The ground floor has twenty-paned sash windows, while the first floor has shorter six-paned sashes. The west front, which was heightened around 1900, also has two storeys and three windows, retaining four-light, two-light, and four-light hollow chamfered granite mullioned windows beneath a continuous granite hood mould. The first floor features sixteen-paned sashes.

Inside, there is a flat baluster stair from around 1700, some post and panel partitioning, and several 18th-century two-panel doors. The kitchen, located in the later part of the house, has a chamfered doorway, a slate flagged floor, a cloam oven in the open hearth, and bowtell moulded ceiling joists. The flanking garden walls to the south are connected to a low granite-coped wall with iron railings and a gate that features fleurs de lys and a scrolled top.
