Description
Trelawny House is an 18th-century building, subsequently altered. The front is stuccoed and scored to resemble ashlar, while the right bay features a rendered ground floor and weatherboard above. The roof is covered with plain tiles. The building is two storeys high with a three-bay arrangement. The original two bays have a central doorway consisting of six flush panels, the top two being glazed, within an architrave that includes pilasters with plain capitals, a frieze, and a cornice. This doorway is currently concealed by a 20th-century trellised lean-to porch, which is not of special interest. Sixteen-pane sash windows are set within flush wooden architraves; those on the ground floor are unhorned, and those on the first floor lack glazing bars to the lower sashes. Brick stacks, with blue headers at the angles, project forward of the ridge. The added right-hand bay contains a horned sixteen-pane sash window on the ground floor, and a 20th-century tripartite window above. Some glazing bars are missing from some of the windows.
