Infants Block at Roath Park Primary School

The Infants Block at Roath Park Primary School is a single-storey school building in Queen-Anne style, constructed in brick with terracotta detail. It comprises 5 main bays and faces north towards Penywain Road. The building has a steeply pitched slate roof behind coped gables, with 4 panelled brick ridge stacks. The roof has been renewed.

The main elevation is distinguished by a central gabled bay brought forward from the wall plane, with outer gabled bays projecting much further forward. Each bay has a coped gable set on moulded kneelers. Between the outer bays runs a low brick wall (former iron railings have been removed) with piers and an iron gate at the centre. Windows throughout have wooden mullions and transoms with small-pane glazing incorporating casements below pivoting lights. All windows have vents beneath the sills, and impost bands mark the central and outer bays.

The central 3-window bay contains single-light outer windows under cambered heads and a 3-light central window with a round-headed tympanum framing a small-pane window beneath a cornice with scrolled stucco wings. The windows have fluted key blocks below pilasters which frame cornices above and below a blind arcade and inscription band. The arcade comprises 2 groups of 3 round-headed openings with key blocks; the central opening contains louvres while the others have blank panels. The inscription band is executed in red Carlisle stone and reads "Infants School" in raised letters. The outer pilasters are crowned by shaped pinnacles (missing on the left side). The apex is occupied by a blank tablet with scrolled sides, cornice and finial.

In the 3-window bays to the right and left of the centre, single-light windows under cambered heads flank a wider 2-light central window positioned between pilasters. This window has an elliptical-headed glazed tympanum similar to that of the central-bay window, with a fluted key block. It projects upward above the eaves under a Dutch gable with segmental pediment and pinnacles crowning the pilasters.

The outer bays each contain two 3-light windows with semi-circular glazed tympana similar to the central bay. Above the key blocks are pilasters framing 3 blind camber-headed openings in the gable, with sill band and cornice. Apex finials are similar to those of the central bay.

The right (west) side wall contains a single large replaced window in an original opening positioned to the right of centre. The architrave has pilasters and is carried above the eaves under a pediment with finials. The rear elevation is plainer, with gabled outer bays between a projecting and wide gabled rear wing, all with replaced windows under cambered heads. The left-hand end bay has 2 windows; to the right of these is a lean-to with an entrance bay added behind it. The entrance bay features a segmental-headed doorway with key block facing west, framed by pilasters and cornice, with replaced doors. The rear wing has 6 narrow windows and 3 vents in the gable. An added lean-to stands on the right side wall of the rear wing against the right-hand end bay, which contains a single window in the lower storey and 3 attic windows above.

The left (east) side wall features a tall central window below a pediment, similar to the west wall, with a single window to its right. Further left is a camber-headed doorway beneath an overlight, followed by a former doorway with pilasters and pediment now converted to a window, and 2 further windows to the left.

The interior is planned around an unusually wide central corridor, probably originally intended as a single school room as well as providing access to the class rooms. The corridor has a boarded wainscot and 2 segmental-headed fireplaces.
