Numbers 20 To 30 And Attached Railings And Gates

A terrace of eleven houses, Numbers 20 to 30 Berkeley Square, was begun in 1787 and designed by Thomas and William Paty. The buildings are constructed of limestone ashlar to the front facades, with brick and limestone dressings to the sides and rear. They have party wall stacks and slate mansard roofs. The architectural style is mid-Georgian. Each house is three storeys high, with an attic and basement, and features a three-window range. The terrace is stepped and articulated by giant pilasters extending to a cornice and parapet, with a rusticated ground floor, a plat band, and a first-floor sill band. The left-hand doorways are framed by Doric pilasters supporting triglyphs and pediments above the fanlights, and feature six-panel doors. Ground-floor windows have key stones and six-pane sashes, while those on the second floor have three-pane sashes. Steps lead down to the basement. Number 20 has a doorway on the right-hand side that is dressed to resemble the ground-floor windows, with a 20th-century door, and an entrance in the left return, constructed of brick with a symmetrical five-window range. This incorporates a large rusticated door surround and a deeply-set semicircular-arched doorway with a fanlight and two-leaf six-panel door, accentuated by five stepped voussoirs over blind windows. A single-storey wall to the left features two doorways, one with a rusticated surround and the other in plain ashlar. Internally, Number 20 features an entrance hall with a frieze, cornice, and fluted dado, leading to an elliptical arch with panelled reveals and a moulded archivolt. A central, open-well dogleg staircase has wrought-iron balusters, a ramped rail with inlaid veneer, and is lit by an oval lantern. A curved hall cupboard has a reeded architrave and marble fireplaces, panelled shutters, and six-panel mahogany doors are present throughout. Number 19 has a right-hand stone dogleg winder stair to the first floor, and a panelled upper stairwell with a domed lantern featuring oculi and plaster decoration. Number 20 contains good marble fireplaces. Attached to the front and basement area are wrought-iron railings and gates, with overthrows to numbers 26 and 28. This design is characteristic of the Patys and likely similar to those originally on Park Street.
