37 And Attached Railings

This is a house, dating to approximately 1790-1793, with alterations in the 19th and 20th centuries, designed by John Palmer. The front is limestone ashlar, the basement is rubble, and the left side is rendered; the rear is rubble. It has a Welsh slate, double-pile, parapeted mansard roof, hipped to the left, with coped party walls to the left and right, and two ashlar stacks to the right. The house stands on the corner of Park Street and Park Street Mews, with access to a rear staircase.

The main facade is three storeys, attic, and basement, with a three-window range. The first floor has three six/six-pane horned sash windows in plain reveals with stone sills. The second floor has three similar sash windows without horns. The ground floor has two similar horned sashes to the rear. A door to the left, with later alterations to the bottom half, features two fielded panels and a single glazed panel to the top, accompanied by a cast iron knocker in a plain reveal and a single pennant step in a pedimented Doric doorcase. There is a single step to a pennant paved crossover with a wrought iron footscraper. The basement has two six/six-pane sashes in plain reveals with a continuous stone sill, a 20th-century glazed door under the crossover, and 20th-century area steps. The attic has a triple dormer with six/six-pane sashes. The exterior details include a band course over the ground floor, a frieze, a moulded eaves cornice and a coped parapet lowered to the centre. The rear elevation, probably rebuilt to accommodate the staircase to the right, has six/six-pane sashes in plain reveals with stone sills, and 20th-century glazed doors to the basement. The interior was not inspected.

Attached to the left of the front door are wrought iron railings with shaped heads on limestone bases, and to the right is a railing and gate with urn tops on limestone bases. The house was built as part of an incomplete development around St James's Square, on land leased in 1790. Lower Park Street forms one of the four diagonal approaches to St James’s Square.
