Ysgol Maelgwyn

Ysgol Maelgwyn is a freestyle Edwardian single-storey school. The long entrance range is brick under a half-hipped slate roof with ridge tiles and two brick stacks. The front is symmetrical, with two wide projecting gabled bays to the central classroom, flanked by three-window entrance bays set back and lower projecting gabled bays housing the cloakrooms, set back from the ends. Above eaves level, the gables are corbelled out slightly and rendered with painted studding. Openings have stone lintels with moulded dripstones. Windows are small-pane horned sashes in wooden frames, some with pivoting small-pane overlights above transoms. The right-hand entrance has half-glazed boarded doors under a freestone tablet with "Boys" in raised letters. The left-hand entrance has a half-glazed door with side panel under a freestone billet cornice and panel with "Girls & Infts" in raised letters. In both entrance bays the doorways are placed on the outer side, with the inner sides having three sash windows of four over single panes, the window next to the door being smaller. The two central classrooms each have three stepped windows, a central broader tripartite eighteen-pane window under pivoting lights, and single eighteen-pane outer windows. Between the gables in the centre is a stone tablet inscribed "Council School 1907" in raised Arts-and-Crafts style lettering. The outer gabled bays each have two paired eight-pane windows.

In each end wall are narrow paired twelve-pane windows, behind which are paired eight-pane windows to projecting gabled back porches. Facing the playground at the rear (south), the porch at the left (west) end has a one-storey brick extension. At the right (east) end the rear porch is in its original form, with a rear outshut against the main range and entrance enclosed by a dwarf wall on two sides. It has a recessed half-glazed boarded door, to the right of which is a three-light window. The rear of the entrance range has replacement windows next to the porches, lighting the corridor.

The central assembly hall is higher than the entrance range and has lower attached classrooms to the east and west walls. All are pebble-dashed under slate roofs, with gables similar to the entrance range. The south gable end of the hall has a stepped window comprising a central tall tripartite twenty-four-pane window with pivoting lights above. On the left side is a narrower paired twenty-four-pane window and on the right side a shorter replacement two-light small-pane window, probably inserted when the rear wing was added. On the left (west) of the hall are two classrooms with gabled west front. Each has a central tripartite eighteen-pane window with pivoting upper lights, flanked by single eighteen-pane windows.

The right (east) side of the hall has two original classrooms with matching detail. It has been extended to the south by adding a short wing with two more classrooms. Facing east, each has paired twelve-pane windows with pivoting upper lights below timber-framed gables, flanked by single twelve-pane windows under overhanging eaves. The south gable end has a two-light double-transomed small-pane window offset to the left side. The rear (west) side of the wing has a lower flat-roofed projection housing a corridor and two small projections, mostly with replacement windows. Above are two three-light flat-headed dormers, the left-hand one having a boarded-up central casement. Further extensions, including an open-sided shed with single-pitch roof and roughcast boiler room with stack, are attached to the south end.

The entrance range has an axial corridor at the rear. Cloakrooms and service rooms are at the ends, with office to the right of centre. Two classrooms are in the centre and on the west and east sides of the hall. The corridor has a glazed tile dado and half-glazed panel door under small-pane overlights. Central classrooms have small-pane upper lights to the corridor and similar small-pane lights to the hall, with boarded wainscots inside. From the corridor is a three-bay arcade with glazed-tile elliptical arches leading into the hall. The hall has a glazed tile dado, incorporating fireplaces in each side wall with blank panels and flat arches. The shallow-pitched corbelled four-bay arched-brace roof has a boarded underside and panelled cornice.
