1A, BRYANSTON SQUARE W1 (See details for further address information)

This is a terrace forming the east side of Bryanston Square, built in 1811 by Joseph Parkinson for the Portman Estate. Numbers 10 to 12 and 19 to 21 were later rebuilt to match the original design. Numbers 1A and 1 to 21, together with numbers 1 and 1A Montagu Mews West and numbers 16 and 18 Montagu Place, are also included in the listing.

The terrace is constructed of brown brick with banded stucco rustication to the ground floor; the end and central houses are entirely stuccoed, with slate roofs. The design is symmetrical, with the end and centre houses being larger and feature Ionic columns and pedimented attics. The terrace comprises four storeys and basements, with some properties later heightened to five storeys. The centre and end houses are each five windows wide, while the intervening houses have three windows. Entrances have panelled doors with sidelights and semicircular fanlights, except for the central and end houses. Most windows are recessed sash windows, a few retaining glazing bars, set within flat, gauged arches. Number 7 has ground floor windows replaced by a single, canted bay. The stuccoed end and centre houses have first and second floors accentuated by Ionic columns, flanking pilasters, and an entablature. The attic storey has pilaster strips, a cornice, a blocking course, and a pediment above the central three bays. The houses between have continuous, cast iron balconies on the first floor and stucco cornices and blocking courses. Cast iron area railings feature urn finials.

Number 1A fronts onto George Street, and is stuccoed with three storeys and five bays. It has a central wood doorcase with Doric columns, triglyphs, a mutule cornice, an open pediment, and a panelled soffit. There are stucco plat bands to the first and second floors, a cornice and a blocking course. The adjoining number 1A Montagu Mews West has a three-storey front with a segmental arched recess containing a garage door and a tripartite window on the first floor; two recessed sashes on the second floor, and a parapet with coping. A plain mews building is located beyond. Number 1 has a Greater London Council plaque indicating that it was the residence of Mustapha Reschid Pasha in 1839. The group value is recognised owing to the terrace’s representation of Georgian London, as documented by John Summerson.
