7, St James'S Street

This is a late 18th century house, likely dating from 1790 to 1793, with alterations from the 19th and 20th centuries. It was designed by John Palmer and is situated at the junction of St James's Street and St James's Square. The house is wider towards the front and narrower to the rear.

The exterior is constructed of limestone ashlar, with some areas painted, and a concrete tile roof. The front facade has four windows per floor. The first floor has two plate glass sashes in splayed reveals to the right, and a six/six sash in a plain reveal to the left. The second floor has two six/six sashes, one in a splayed reveal and the other in a plain reveal, both with stone sills. The third floor mirrors the pattern with six/six sashes and stone sills. The ground floor has two 20th-century six/six sashes to the right and a late 19th-century six-panel door within a pedimented Doric doorcase featuring panelled stone pilasters, a timber entablature, and a pediment. A small 20th-century window with decorative guarding sits to the left of the door. The door and pilasters are remnants of a later 19th-century shopfront, largely replaced in 1982. Architectural details include a shallow plinth to the right, a band course above the ground floor, a sill band on the first floor to the left, a moulded cornice over the second floor, a moulded eaves cornice, and a coped parapet. Evidence suggests a former balcony with a tent roof on the first floor right, along with a likely 20th-century hanging sign bracket. The rear elevation has glazing-bar sashes and a wrought iron balconette on the first floor, along with a four/four sash window and a 20th-century six-panel door on the ground floor.

The interior was not inspected but is reported to feature an unusually planned staircase with a damaged balustrade.

The property forms part of an incomplete development of St James's Square, which was established on land leased in 1790. St James's Street is one of four diagonal approaches to St James’s Square and exemplifies the application of Picturesque principles to urban planning.
