21 and 22, Sydney Buildings

Two houses, originally one, stand on a sloping site alongside a canal. Built around 1820, the property includes a late 19th-century lean-to wing to the left, with 20th-century alterations. The construction utilizes limestone ashlar, topped with a double-pitched double Roman tile roof and moulded stacks to the coped gable ends. The original layout consisted of a double-depth square plan, with later additions.

The exterior presents three storeys and a lower ground floor, initially a two-window range. Coped parapets, a cornice (simpler on the returns), and platbands wrap around the building. The second floor features three/three-pane sash windows, while the first floor has six/six-pane sashes and the remaining windows are plate glass. A courtyard fronts the property, covered by a roof between the houses and a rubble stone street wall approximately 4 metres high, which slopes down to the left following the roofline of a single-storey lean-to wing. A late 19th-century two-storey lean-to wing is located to the left return, incorporating a tall stack that matches the height of the original house's stacks. A 20th-century two-storey porch with a six/six-pane sash window above a 20th-century door is on the right return. The rear elevation mirrors the front, with plate glass sash windows.

The interior of the main house was not inspected. Number 21, which comprises the left-hand part of the original house, was surveyed by the Bath Preservation Trust Interiors Survey. This revealed a cantilevered stone staircase of four flights with wood (and some iron) railings and a mahogany handrail, three rooms per floor, and plaster acanthus leaf cornices with reeding in several rooms. This is one of the larger late Georgian houses on the Bathwick estate and its appearance reflects the importance of the canal and associated activities.
