No. 4 and Attached Railings

House. Built around 1777 to 1784, with alterations in the 19th and 20th centuries, by John Wood the Younger. The front is faced with limestone ashlar, while the rear is a combination of ashlar and rubble. It is a double-pile house with a parapeted mansard roof, raised to accommodate rooms in the roof space. The roof is covered in Welsh slate to the front and rear, with a coped gable end and two ashlar chimney stacks, some incorporating early clay pots.

The house is three storeys high, with an attic and basement, and has a three-window front. The first floor has three six-over-six horned sash windows, set within splayed ovolo moulded architraves, with friezes, moulded cornices and lowered moulded stone sills resting on console brackets. The second floor mirrors this design with similar windows and detailing. The ground floor has two six-over-six horned sash windows to the right, and a six-panel door to the left, within a stone doorcase featuring a cyma moulded architrave and a moulded cornice, also supported by console brackets. A pennant-paved crossover is flush with the pavement. The basement has two six-over-six sash windows, a 20th-century door in an ashlar infilling, and no area steps. A double dormer window with six-over-six sashes is visible from the front. Architectural details include a band course over the ground floor, modillion eaves cornice and a coped parapet. A lead downpipe is shared with No. 5 Catharine Place.

The rear elevation features glazing bar sash windows, a cantilevered lavatory extension rendered with a small two-over-two sash window on console brackets with roundel decoration, and a 20th-century conservatory at ground floor level, along with a double dormer window.

Interior details were recorded by the Bath Preservation Trust in 1989, revealing that much of the original moulding and frieze decoration on the ground floor remains intact. Two-panelled cupboards in the front room are believed to be former sword cupboards, and connecting two-leaf double doors with large brass hinges are present on the first floor. The basement and upper floors were remodelled in the 1970s.

Attached to the front are wrought iron railings and a gate with shaped heads on limestone bases.
