Large late-Victorian chapel in restrained Italianate style. Of limestone construction with symmetrical ashlared facade and slate roof, half-hipped to the gable ends; 2 metal louvres. Four-bay, single-storey porch block advanced to the centre. This has a pair of round-arched entrances with flanking arched windows; projecting imposts and keystones. Six-(sunk)panel doors with plain segmental fanlights. Flanking and end pilasters supporting a plain entablature with moulded cornice. Surmounting this is a columnar stone balustrade with moulded rail. The porch returns have similar arched windows; all have plain sashes with marginal glazing. Flanking the porch are further, square-headed entrances with plain pilasters supporting entablatures; doors as before, with plain rectangular fans. To the L and R (respectively) of these entrances are tall outer stair windows, arched and glazed as before, with corbelled sills, flush voussoirs and projecting keystones. The upper, gallery floor, has 4 further, similar arched windows with continuous moulded label running the length of the facade. Modillion eaves cornice. The L gable end, facing Beacon's Hill, has three 8-pane sashes to each floor, with cambered heads and marginal glazing.
Adjoining the chapel at its northern corner, with its facade facing Beacon's Hill, is the School Room. This consists of a large hall raised above a basement storey with a high chamfered plinth. Asymmetrical limestone ashlar facade with moulded wooden cornice and hipped slate roof; 2 metal louvres. Of 5 bays, the second (from L) is advanced and gabled and has moulded bargeboards and an end chimney with simply-decorated capping. This bay has a 16-light recessed sash window with further 3-light section above; flat stone lintel and projecting sill. Above this is a stringcourse, continued onto the other bays as an eaves course; raised date to the gable apex: 'AD 1892.' The flanking L bay and the 2 bays to the R have similar, narrower windows of 12 panes. The right-hand bay is recessed and has a narrow 6-pane window, similar to those before, and a recessed 6-panel door to the return with moulded panels and a 6-pane rectangular overlight. 12-pane sashes to the basement with an entrance to the advanced bay; part-glazed double doors with rectangular overlight.
The chapel and schoolroom are fronted by low forecourt walls of rough-dressed rubble with dressed, chamfered copings. These step down in stages from the upper to the lower end of Chapel Street, and then turn at right-angles to follow the line of the descending Beacon's Hill. to a point immediately beyond the schoolroom. At the upper end, to the R of the chapel, and at the lower end, opposite the schoolroom entrance, are stone gatepiers with chamfered bases and pyramidal capping stones. Opposite the chapel porch are a pair of larger, rusticated gatepiers with similar capping. Simple iron gates to these, together with a surviving stretch of similar railings sweeping from these piers down to the point at which the chapel meets the schoolroom.
