Description

Trefnant School House is a schoolmaster's house built in a restrained Tudor-Gothic style, located next to the school at the rear. The structure is made of uncoursed, roughly-dressed limestone blocks with tooled ashlar dressings and features slate roofs with overlapping copings on the gable parapets. It has two staged chimneys with splayed sides, chamfered tops, and cornice bands. The building has a double-pile plan, with the left (northwest) pile being slightly larger and advanced compared to the right pile. Both sections have steep gables.

The right section, which serves as the entrance, features a shouldered arch with stopped-chamfered jambs and an expressed, pointed relieving arch, along with the original recessed, boarded door. Above the entrance, there is a rectangular window with chamfered jambs, a splayed sill, and iron-framed lozenge glazing, which was boarded at the time of inspection in July 1997. A flush stepped buttress is located on the narrow right return between the school house and the main school building, with the school house slightly advanced in front.

The left pile includes a 3-light mullioned window on the ground floor and a 2-light window on the first floor, both featuring similar glazing and segmental and pointed relieving arches, respectively, with some replaced casement sections. There is a single light window with a 2-light window beyond on the long left return, along with additional similar windows on the first floors of the paired flush rear gables. The right gable has a contemporary single-storey lean-to projection with overlapping parapets on the slate roof, featuring a 2-light mullioned window at the front and a single-light window on the side. The left gable has a modern 2-storey flat-roofed extension made of rendered brick. In front of this extension, there is a small contemporary walled service court with a Ty Bach in one corner.

Inside, the house has plain contemporary interiors with 4-panel doors and a straight-flight pitch-pine stair featuring a turned newel and plain balusters.
