Trewarren

Trewarren is a country house featuring a roughcast exterior, hipped slate roofs with deep eaves, and rendered corniced ridge stacks. The building is designed in a U-shape and consists of two storeys, with a long south-facing front that has six windows, a four-window east entrance front, and a five-window west side, which is partly three storeys high. The eaves are moulded.

The south front has a slightly projected central section with two windows, where the roof continues over. It features six large 12-pane sash windows without horns on the first floor, with slate sills, and six full-length ground floor 12-pane sash windows with horns, which may have been a later 19th-century alteration. These windows are set within a slated six-bay open veranda supported by slim tapering timber posts, with slate paving and a single step.

The east front has a similar four-window arrangement on the first floor, although the left window is blank. The ground floor features blank arched recesses on both sides, with three arched openings in the centre. The outer openings contain windows with fixed Y-tracery timber glazing, while the centre has a half-glazed door with a Y-tracery fanlight. There are two ridge stacks on this side.

The west end includes a south-facing conservatory with a monopitch roof, built on a brick base against a rubble wall. The main house's west wall is rendered and has five ridge stacks, with the right stack resembling those on the east ridge, while the others are made of black brick. There is a basement window with six panes on the right, followed by a five-window range of 12-pane sashes on the ground and first floors, except for a door in the left end bay. The second floor features six-pane sashes under the eaves in the left four bays, all with slate sills.

The rear of the house has three hipped roofs, with a recessed centre that includes a tall arched stair-light on the left, featuring double marginal glazing bars, and a large 12-pane sash window on each floor to the right. The east wing has a west door with a 12-pane sash window above it, and a small window to the right at half-level. The longer west wing has a 12-pane sash window in the left angle of the first floor, above a door, and another 12-pane sash window to the right on the first floor. The end walls are windowless.

The interior has an axial cross passage plan with the main stair located to the centre right and the principal rooms to the left. The stair features a cast-iron balustrade. The property has not been inspected.
