Numbers 1 to 8 and Attached Railings and Gates

Numbers 1 to 8 Berkeley Square form a terrace of eight houses begun in 1787, designed by Thomas and William Paty. The houses are constructed of limestone ashlar to the front, with brick and limestone dressings to the sides and rear. They have slate mansard roofs, brick party wall stacks, and three storeys plus an attic, with a basement. Each house originally had a three-window front.

The terrace is articulated with giant pilasters extending to a cornice and parapet, a rusticated ground floor, and a first-floor sill band. The right-hand doorways feature Doric pilasters, triglyphs and pediments above fanlights, with six-panel doors. Ground-floor windows have key stones and six-pane sashes; those on the second floor have three-pane sashes. Steps lead down to the basement. Number 1 has a four-window front and a single-storey porch with a six-panel door and curved steps. There are five stepped voussoirs to blind windows, glazed to the left-hand side.

The interiors retain good quality joinery and plasterwork. Features include entrance halls with friezes, cornices, and fluted dados, an elliptical arch with panelled reveals and a moulded archivolt, a central stone dogleg staircase with wrought-iron balusters and a banded, ramped rail, lit by an oval lantern with oculi, plaster decoration, marble fireplaces, panelled shutters, and six-panel mahogany doors.

Attached to the front of the basement area are wrought-iron railings and gates. The design is characteristic of the Patys and is likely similar to those originally on Park Street. The terrace forms the west side of Berkeley Square, which was originally planned to be open to the south.
