Gymnasium And Music Room At Number 10 Sheffield High School For Girls

The gymnasium and music room at Number 10 Sheffield High School for Girls, originally a Congregational church and Sunday school, dates to approximately 1870, with the Sunday school constructed in 1929. The building was later converted for its current use in the late 20th century. It is built of coursed squared stone with ashlar dressings, featuring gabled and hipped slate roofs with decorative ridge tiles and coped gables. The design is in the Gothic Revival style.

The building's plan features an apsidal east end, a crypt, a south-east tower, transepts, an aisleless nave, a lobby, and a west porch. The east end is canted and incorporates a string course and angle buttresses, with three cusped round windows above a two-light stone mullioned window flanked by single-light windows, all featuring shouldered heads. The crypt has six reglazed windows separated by buttresses. A small lean-to projection on the north side contains a single shouldered window.

The south-east tower, adjacent to the transept, has a patterned slate pyramidal roof with a finial, moulded eaves, and a large coped side wall stack. It has a blank middle stage and a small bell stage above a string course, with three small cusped openings on three sides. The lower stage has two shouldered windows, a crypt door with an overlight, and two stepped shouldered stair windows to the right. The south transept displays a two-light pointed arch window above a wheel window, with three pointed arched openings below, each containing a three-light window. A cusped-headed double door is to the left. The west transept features a two-light pointed arch window. The north transept has a pointed arched recess holding a traceried wheel window and two plain two-light pointed arch windows below. Further two-light windows with plate tracery are present to the east and west of the nave. The west end has a similar five-light window with plate tracery and a hoodmould. The transverse lean-to lobby features a chamfered coped parapet and end walls forming coped buttresses. The central west porch has a coped gable flanked by gabled angle buttresses topped with pinnacles and spires, a moulded segment-arched doorway with single marble shafts, a hoodmould, and double board doors. Small lancet windows are positioned on either side of the doorway, with louvres on the right.

Inside, a moulded arch leads to the east end, featuring a hoodmould and enriched impost band. The apse has three windows with hoodmoulds and a sillband with corbels. The nave and transepts have principal rafter roofs, with principal rafters in the form of strutted wooden girders, false hammer beams, and moulded stone corbels. A shaft respond sits on a corbel at each west corner of the crossing. A pointed arched door is located in the east of the south transept. The nave’s west end has two panelled doors. No original fittings, memorials, or stained glass remain.
