Welsh School

The Welsh School is a Gothic-style building constructed in 1874. It features a one-storey, nearly symmetrical north front with five buttressed bays and gabled wings at both ends. The exterior is made of rubble facings with freestone dressings, and yellow brick is used for the eaves and plinth courses, as well as more extensively on the rear elevation. The steep slate roofs have ridge cresting, and there is a square bellcote on the ridge topped with a spirelet, weathervane, and cusped lucarnes.

The central gablet has a pointed window with triple lancets arranged in echelon, while the lesser windows are shouldered tripartites, with a modern porch to the left. The outer gables feature 4-light windows. The side gables also have 4-light transomed windows with quatrefoils above. The elevation facing Park Avenue has a stepped design with 2-and 3-light shouldered lights, a tall tapered chimney stack, and ornamental iron grille covers. The original ironwork railings with finials add to the building's character.

Inside, the Assembly Hall in the north range has a five-bay interior with A-frame trusses that are boarded above the tie-beams. Arched braces are supported by mid-wall corbels, with double braces at the center, all adorned with pierced quatrefoils and chevron ornament. The original timber architraves have crossover corners, and there are braced and boarded doors along with boarded dados. The flanking classrooms have similar detailing and open roofs, although they now feature lowered ceilings and modern partitions. A tablet in the Assembly Hall indicates that the building opened on 4 August 1874, designed by architects Szlumper & Aldwinckle.

The wings have been extended to the south, incorporating some details from the 1890s along with modern alterations.
