No. 21 Parliament Street is a house that has been converted into offices. It was built around 1797 and has undergone some alterations in the 19th century. The building is constructed of brick and features painted ashlar dressings, topped with a slate mansard roof that includes a gable stack. It has a plinth, ground floor, and first-floor sill bands, along with a slab-coped parapet. The windows are adorned with brick flat arches. The structure stands three storeys high, plus a basement and attics, and has a three-window range of 15-pane sashes, with three 9-pane sashes above. There is also a square dormer featuring a 3-light glazing bar Yorkshire sash.

On the ground floor, to the left, there is a wooden doorcase with Doric three-quarter columns, a dentillated cornice, and a pediment. The round arched doorway has steps leading up to a fielded six-panel door with a blank fanlight above. To the right of the doorway, there are two 12-pane sashes. Below the windows, there are two fielded six-panel double doors that alternate with moulded stucco panels.
