No.28 and Attached Railngs

No. 28 is a house, now converted to flats, dating to circa 1790-1793, with alterations in the 19th and 20th centuries. It was designed by John Palmer. The front is constructed of limestone ashlar, while the rear features ashlar and rubble. The roof is a mansard with Welsh slate, a coped gable wall, two ashlar stacks, some early clay pots, and a staircase to the front.

The house is three storeys, with an attic and basement, and has a three-window front. The first floor has two 19th-century plate glass sash windows with wrought iron balconettes to the right and a nine/nine-sash window to the left. The second floor has two plate glass sash windows with window guards to the right and a six/six-sash window to the left. The ground floor features two plate glass sash windows with stone sills and wirework balconettes to the right, and a six-panel door set within a pedimented Doric doorcase, with a cast iron lion's mask knocker, plus a small window with a wrought iron guard to the left. A concreted crossover is present. The basement has two six/six-sash windows with a continuous stone sill, a 20th-century glazed door in an ashlar infilling, and limestone steps with pennant treads. A single raking dormer with a plate glass sash window is located at the rear. Architectural detailing includes a band course over the ground floor forming the sill band to the first-floor windows, a sill band to the second-floor windows, a frieze, a moulded eaves cornice, and a coped parapet. The rear elevation incorporates largely 19th-century plate glass sashes and a mansard extending the building to a full third floor.

The interior was not inspected, but is noted to have a Chinese Chippendale balustrade to the first-half landing.

Attached to the property are wrought iron railings and a gate with shaped heads on limestone bases.

The house is part of an incomplete development of St James’s Square, built on land leased in 1790. The upper part of Park Street commenced to the design of John Palmer and later continued by John Pinch after 1808. Originally, the street terminated at All Saints’ Chapel and was intended to continue in a northwest direction as Regent Place.
