St Joseph's School, 1 Queen's Road, Aberdeen

St Joseph's School, located at 1 Queen's Road, Aberdeen, is a villa dating from around 1880, likely designed by Matthews and Mackenzie. Minor alterations were carried out in 1902 by A Marshall Mackenzie, and further links were added in 1911 and 1923 by W J Devlin to connect it with the buildings at 3 Queen's Cross and 3 Queen's Road (listed separately). Originally a detached building, it is now incorporated into that complex.

The villa is two storeys plus basement, with a rectangular plan and three bays. It is constructed of tooled coursed grey granite with contrasting light grey dressings, displaying features such as a base course, panelled aprons, long and short rusticated quoins, an eaves course, and overhanging eaves supported by brackets. Granite rubble is used on the southeast elevation.

The northwest elevation, which serves as the principal facade, demonstrates a symmetrical design. Two tripartite windows are present on the basement floor, enclosed by a low wall and railings. A distyle Tuscan porch advances centrally to the ground floor, with pilasters framing a panelled timber door with a letterbox fanlight, accessed by five stone steps. The ground floor also features corniced and architraved tripartite windows with pilastered astragals in the flanking bays. Regular fenestration is consistent across the first floor.

The southwest elevation is largely obscured by a link structure built in 1923 by W J Devlin. The southeast elevation is near-symmetrical with five bays and incorporates a round-arched leaded glass window positioned between the ground and first floors. A timber door is flanked to the right by a window, with a flight of iron steps and railings leading to the garden. The basement floor has regular fenestration, with single windows in the penultimate bays to the left and right, and bipartite windows in the outer bays. The first floor also has near-regular fenestration. Modern skylights have been added to the attic floor, alongside extensions by W J Devlin to the outer left and right.

The northeast elevation is obscured by a link structure built in 1911 by W J Devlin.

The building’s fenestration is dominated by predominantly two-pane and four-pane timber sash and case windows. The roof is a piended grey slate structure with lead ridges, topped with a corniced wallhead stack and octagonal cans. Cast-iron rainwater goods are also present.

The interior retains many original features, including mouldings, architraves, and panelled doors. A panelled timber inner door with glazed upper panels, a simple fanlight and a depressed arch on fluted pilasters with a moulded keystone lead to a dog-leg staircase with decorative iron balusters and a leaded and stained glass stair window. A panelled principal room on the east side of the ground floor (painted) features round-arched niches flanked by slender pilasters, a deep coved frieze ornamented with cartouche details, some bearing the letter "B" (likely the initial of the original owner), a dentil moulded cornice, and panelled shutters. A decorative marble fire surround is located in the headmistress's office.
