Description

Tregarne is an Arts and Crafts style house built in two storeys, featuring a picturesque and asymmetrical design. The exterior is roughcast rendered and whitewashed, topped with a green graded slate roof that has feathered projecting eaves, yellow clay ridge tiles, and rectangular rendered chimney stacks.

The main elevation facing the street includes a two-storey block on the left with end wall stacks, highlighted by a prominent left-hand gable that has a decorative tile motif at its apex. The entrance is set back in a round-arched porch to the right, with a small window above it. Beneath the gable, there is a small paned casement window with three lights. To the right of the entrance is a one-and-a-half-storey block with a separate roof that slopes down low to create a loggia, featuring two 2-light small paned casements and a long horizontal dormer in the roof. The return elevation to the right has similarly styled casement windows and a single-storey wing with a hipped roof. The rear elevation has paired gables with similarly detailed casements, and to the right, there is a bay window with modern lights. The return elevation to the left features a single fixed light.

Inside, Tregarne retains many original features, including doors, cupboards, bedroom fireplaces, and fittings in the upstairs bathroom. The staircase is also original, featuring diagonally set stick balusters interspersed with plain splats that are pierced with heart shapes.
