No.10 And Attached Railings

No.10 is a house, now a nursing home, built around 1790 to 1793, with alterations in the 19th and 20th centuries. It was designed by John Palmer. The front is faced with painted limestone ashlar, while the basement is of limestone rubble. It has a Welsh slate, double-pile mansard roof, a coped gable wall to the left, and two rebuilt ashlar stacks to the right end, retaining some early clay pots. Situated on the corner of Park Street and Park Place, the main entrance is to the left of the Park Street frontage.

The house is three storeys high, with an attic and cellar, and features a three-window front. The first floor has three plate glass sash windows in plain reveals, with a continuous stone sill; the left and right windows are narrower than the centre one. The second floor has similar fenestration, with one plate glass sash flanked by two blind windows. The ground floor mirrors the first, also with three sashes. The basement has two six-over-six sash windows in plain reveals, with a continuous stone sill. A likely 19th-century ashlar extension, altered in the 20th century, provides access steps. Blocked dormers are present; one has a six-over-six sash with a moulded architrave. Architectural features include a timber bressumer and stone band course over the ground floor, a moulded stone eaves cornice and coped parapet. The narrow rear elevation has a six-over-six sash window at the first-floor landing and a nine-pane tilting window on the second floor. The left side facing Park Place has two plate glass sashes on each of the first, second, and ground floors, along with two six-over-six sashes in similar reveals to the attic. A small-paned sash window is set into the basement to the left. The front entrance is a six-panel door in a Doric doorcase with reeded and raised and fielded panels, and glazed upper panels. It is approached by four pennant stone steps. A deep plinth, timber bressumer, stone band course, and continued eaves mouldings run the length of the building, tying in with No.1 Park Place.

The interior has not been inspected. Attached to the front are wrought iron railings and a gate with shaped tops on limestone bases. The house was part of an incomplete development of St James's Square, with work continuing after 1808 under John Pinch. The original street terminated at All Saints' Chapel and was intended to extend northwest as Regent Place.
