No.7 And Attached Railings

This is a three-storey, attic, and basement terrace house, now used as flats, completed in 1790 with 19th-century alterations. It was designed by John Palmer and built by Charles Viner as part of an incomplete development around St James’s Square, on land leased in 1790.

The front of the house is built of limestone ashlar, painted on the ground floor. The rear is a combination of rubble and ashlar, topped with a Welsh slate, parapeted mansard roof raised to a full third floor to the rear. There are two ashlar chimney stacks with some early clay pots on the front, within a coped party wall to the left. The house is a single bay with a three-window front. The first floor has three grouped plate glass sash windows, narrower on the left and right, set in splayed reveals with a continuous stone sill and a wrought iron balconette. The second floor has three similar windows in plain reveals with a continuous stone sill. The ground floor includes a two-over-two horned sash window in a splayed reveal with a stone sill, and a six-panel door with flush, fielded, and glazed panels, featuring 19th-century door furniture within a moulded architrave. A stone sill and wrought iron window guard with shaped heads to the bars are present on a basement window, along with a six-panel door and window within ashlar and concrete blockwork. A raking double dormer features plate glass sashes. A timber bressumer, stone band course, frieze, moulded eaves cornice, and coped parapet are continuous with No.8 Marlborough Street.

The rear elevation has 19th-century windows, including a round-headed window with a coloured glass border on a first-half landing balconette. The roof has been raised to the full third floor, and a further ashlar extension is present to the basement and ground floor, with attached wrought iron railing. The interior was not inspected during the listing process.

Attached to the house are wrought iron railings with cast arrowhead motifs on limestone bases. The property’s historical context includes an underlease to Charles Viner in 1790, lasting 96 years, and its place as one of the four diagonal approaches to St James’s Square. The property's construction is documented in deeds and maps from 1856.
