St Mary's Workshops, 67 Giles Street, Leith, Edinburgh

St Mary's Workshops, located at 67 Giles Street, Leith, Edinburgh, were designed by James Simpson and built between 1875 and 1876. George Craig later enlarged and heightened the building in 1888. Originally a school built in the French 18th century style, it has been converted into workshops.

The building is two storeys with a mansard attic, and comprises twelve bays. It is constructed from cream-coloured sandstone, with squared and snecked rubble and polished dressings. A base course, a band course above the ground floor, and detailing at the eaves level are notable features. Segmental-arched windows are present throughout. The front elevation has corniced windows on the wings at ground floor level, with bracketed cills at the first floor. Ornamental cast-iron ventilation grilles are recessed on both the ground and first floors.

The east (front) elevation is nearly symmetrical, with eleven bays. A four-bay central block is advanced with bipartite windows and a pedimented dormer featuring scroll flanking. The outer bays are also advanced, with the third floor breaking the eaves in a similar manner with dormerheads and French pavilion roofs. The four-bay outer wings are angled forward with outer bays slightly advanced; they feature corniced doorways with tall fanlights (the fanlight on the outer right is blind, bearing an inscription).

The west (Henderson Street) elevation is fourteen bays, with a six-bay central block and advanced outer bays as seen on the east elevation. The centre bays have bipartite windows, and pedimented, scroll-flanked dormers. A four-bay wing to the left is angled, with outer bays slightly advanced, and a four-bay wing to the right incorporates a tall, shoulder-arched arcade of recessed play shelters at ground floor level; advanced outer bays have pavilion roofs.

Two scroll-flanked bull’s-eye metal dormers with antifixae are also present.

The north (Spier's Place) elevation is five bays and includes an advanced stair tower to the centre with windows displayed vertically in ashlar panels. A pedimented section breaks the eaves at the second floor, topped with a pavilion roof and single windows on the returns. The south elevation has two arcade openings for play shelters and single windows above and to the right of centre, with pavilion roofs to the outer bays.

Most windows are timber sash and case, predominantly with two-pane upper sashes and four-pane lower sashes. The slate mansard roof has metal flashings, and central stacks. Octagonal gutterheads are present.

The interior has been converted into small workshop units.

A low boundary wall with iron railings sits around the property.
