Deptartment Of Works, University Of Edinburgh, 9 Infirmary Street, Edinburgh

The Department of Works at the University of Edinburgh, located at 9 Infirmary Street, is a former church designed by William Sibbald between 1803 and 1805. This Neo-Jacobean building features a symmetrical three-bay nave and aisle with curvilinear gables. It is now internally connected to an early 19th-century two-storey, six-bay Classical office building (No 11) on the right, and has a single-storey pavilion on the left. The exterior is constructed of ashlar stone, with some raised margins on the church and rubble at the rear. It includes a base course, a band course on the pavilions, and a cornice, along with raised cills. The church and the ground floor of No 11 have round-arched openings, and there is a timber entrance door with a semi-circular fanlight above on the far left.

The former church features a slightly advanced central bay with three hoodmoulded round-arched openings at the ground level, which contain two-leaf boarded timber doors adorned with metal studs and decorative metal hinges, along with three-light semi-circular fanlights above. The large central window has four lights with curvilinear tracery, flanked by smaller three-light tracery windows. The building is also accented with polygonal corner pinnacles.

The office building (No 11) predominantly has 12-pane timber sash and case windows and is topped with grey slates. The pavilion to the left has a piended roof.

Inside, as seen in 2007, the space has been extensively altered to accommodate workshops and offices, featuring barrel vaulted basement rooms and some decorative plaster cornicing.
