21 Queen Street, Edinburgh

21 Queen Street is a former terraced classical house built around 1785, with mid-19th century alterations. It is a three-storey building with a basement and attic, featuring a three-bay façade made of cleaned droved ashlar Craigleith sandstone. The ground floor displays polished V-jointed rustication, and to the left is a tripartite pilastered doorpiece with a fluted frieze. The entrance includes a flush panelled door topped with a large plate glass fanlight and an Edinburgh handle. The cill course on the first floor has been altered by lowering the cills. The roof has a pair of small piend-roofed dormers.

The rear elevation is constructed of coursed rubble, added in the 19th century. The building has timber sash and case plate glass windows, with 12-pane windows in the dormers. The roof is covered with grey slates and features ashlar coped mutual skews, which are lead covered, along with dressed stone mutual stacks that have been reduced to the west.

Inside, the building has been thoroughly and plainly refurbished in the 19th century and is currently used as an office. It is connected on every floor to No 22. The property also has late 19th century cast-iron railings that match those at No 22.
