No.41 and Attached Raiklngs

No. 41 and its attached railings are a house, dating from circa 1790 to 1793, with alterations in the 19th and 20th centuries. Designed by John Palmer, the house is located at the corner of Park Street. The front is limestone ashlar with a rubble basement, while the rear is constructed of rubble. The roof is an artificial slate mansard roof with two ashlar stacks. The house has a short, splayed section of façade on its left side, a staircase to the front left, and a narrow rear elevation.

The three-storey, attic, and basement house has a two-window front. The first floor features six/six-sash windows; the left window is in a plain reveal with a stone sill, and the right window is in a splayed reveal with a stone sill and a wrought iron balconette. The second floor has a six/six-sash window on the left with a stone sill, and a 19th-century horned two/two-sash window on the right in a similar reveal. The ground floor has a plate glass sash on the right, in a splayed reveal with a timber lintel and stone sill, and a six-panel door with flush, fielded, and glazed panels, set within a pedimented Doric doorcase with a single pennant step and a crossover paved with pennant stones. The basement has an eight/eight-sash window in a plain reveal with a stone sill, a 20th-century glazed door and screen under the crossover, and 20th-century area steps. There is a single dormer with a two/two-sash window. Features incorporating the exterior include a timber bressumer, a stone band course over the ground floor, a frieze, a moulded eaves cornice, and a coped parapet. A Sun Fire Insurance plate is located in the centre of the first floor. The rear elevation is partially visible and includes six/six-sash windows to the first and second floors, with a wrought iron balconette and lead hopperhead and downpipe on the first floor. The interior has not been inspected.

Attached to the property are wrought iron railings and two gates with cast arrow heads on painted bases. The house is part of an incomplete development of St James’s Square, built on land leased in 1790; the lower part of Park Street forms one of four diagonal approaches to the square.
