No.25 And Attached Railings

No. 25 is a house, built in 1808 and subsequently altered in the 20th century, originally designed by John Pinch. It is now used as flats. The front is constructed of limestone ashlar, with rendered surfaces to the left side and at the rear, utilising limestone rubble. The double-pile, parapeted roof has a hidden front covering but features Welsh slate to the rear, with coped gable ends and two ashlar stacks to the rear, some with old clay pots. A staircase is located at the rear.

The building is four storeys and has a basement, with a three-window front. The first floor has 19th-century plate glass sash windows with iron balconies, similar to those at No. 26 Park Street. The second floor has three similar windows without balconies; the third floor has two windows with stone sills and one blind window. The ground floor contains two similar windows to the right, and a six-panel door with reeded and raised and fielded panels, topped by a decorative fanlight within a square-headed reveal with rounded arrises, approached by a single pennant step, and a converted crossover with 20th-century area steps. A band course runs along the ground floor, serving as a sill band to the first floor windows, followed by a sill band to the second, a frieze, a moulded cornice above the second floor, a moulded eaves cornice, and a coped parapet. Two small windows from the 19th century are visible on the left side. The rear elevation includes 19th-century windows and a two-storey extension leading off the stairs from the second to third half landings. The interior was not inspected.

Attached to the front are wrought iron railings and a gate with shaped tops and limestone bases. The house was part of an incomplete development of St James’s Square, on land leased in 1790; the upper part of Park Street was started to the design of John Palmer, later continuing, but not completed, to the design of John Pinch after 1808. Originally, the street was terminated by All Saints Chapel and was intended to be extended northwest as Regent Place.
