Trefnant School

L-shaped school range in restrained Tudor-Gothic style, with adjoining master's house to rear. Of uncoursed, roughly-dressed limestone blocks with tooled ashlar dressings; slate roofs with overlapping copings to gable parapets and 3 metal louvre bases to roof sections, the louvres lost. Tall chimney with splayed sides, chamfered top and cornice band. The entrance front is of 3 bays, that to the L advanced and gabled and with a catslide roof extension continuing R over a flush, central porch. The gable has a pair of tall lancets with an oculus above, the whole contained within a large, flush ashlar arch; the original iron intersecting lozenge glazing survives to the oculus, otherwise plain modern glazing. Pointed-arched entrance, stepped-up and with modern panelled door; plain triangular overlight. The right-hand bay has a large square window with tripartite modern glazing; blocked lancet group window to R gable, as before; modern extensions adjoin here (NE). Three further large square windows to long L side (SW).

Plain modernised interiors with modern partitioning and false ceilings obscuring primary open roofs to main and lesser class-room halls.
