No.26 and Attached Railings

No. 26 is a house, now converted into flats, built in 1808 with alterations made in the 20th century. It was designed by John Pinch. The front of the building is faced with limestone ashlar, while the rear is a combination of limestone ashlar and rubble. The roof is hidden from view at the front and is covered with clay pantiles to the rear, featuring a coped wall and two ashlar chimney stacks with some original clay pots. A rear staircase is also present.

The building is four storeys and has a basement, with a three-window arrangement to the front. The first floor incorporates six-pane sashes in plain reveals accompanied by wrought iron balconies. The second floor has two six-pane sashes in plain reveals, complemented by wrought iron window guards and a central blind window. The third floor features two three-pane over six-pane sashes in plain reveals with stone sills, alongside a similar central blind window. At ground floor level, there are two six-pane sashes on the right and a six-panel door with reeded and raised panels, with two upper glazed panels and an overlight, leading to a pennant paved crossover with a cast iron footscraper. The basement contains two six-pane sashes and a half-glazed door with steps. Horizontal bands run above the ground floor and second floor windows, and above the second floor is a frieze and moulded cornice topped by a coped parapet. The rear elevation retains early-design glazing bar sashes in some rooms, with 19th-century sashes in the staircase area, and a single-and-a-half-storey extension to the rear. The interior has not been inspected.

Attached to the property are wrought iron railings and a gate, set on limestone bases with shaped tops. The building is part of the incomplete St James's Square development, which originated from a lease agreement in 1790. The upper section of Park Street was initially designed by John Palmer and subsequently continued by John Pinch after 1808. The street was originally terminated by All Saints Chapel and was intended to be extended north-westwards as Regent Place. The building showcases stop-chamfered spine beams with run-out stops.
