15, Northampton Street

This is a house, built after 1819, with a 20th-century addition. It was designed by G.P. Manners. The front and rear are constructed of limestone ashlar, with a parapeted roof. The front has Roman-style tile copings and stacks made of reconstituted Bath stone; the rear stacks are ashlar and currently without pots.

The house is two storeys with an attic and basement, and has a two-window front. The first floor has an eight-pane over eight-pane sash window with a plain stone sill and wrought iron balconette on the left, and a six-pane over six-pane sash window to the right. The ground floor has a similar sash window on the left and a six-panel door with moulded panels and fielded panels, with voided corners, above a concrete step, protected by a round-headed reveal and with a plate glass fanlight. A basement window is partially above ground level, with a grating set in the pavement, and a small window with a 20th-century guardrail to the left. There is a double dormer with six-pane over six-pane sashes. The building features a moulded eaves cornice and a coped parapet. The rear elevation contains glazing bar sashes and a double dormer with plate glass, horned sashes. The interior has not been inspected.

Northampton Street and its surroundings began to be developed around 1791, according to a design by Thomas Baldwin, as trustee for William Pulteney. Development continued from 1794 following the bankruptcy of the main contractors, with plans and elevations included in leases signed by Thomas Chantry and John Pinch. The house was completed after 1819, according to plans and elevations featured in leases signed by G.P. Manners. The building suffered bomb damage in 1942, which significantly impacted the lower part of the street.
