88, Harley Street W1

No. 88 Harley Street is a terraced first-rate town house built around 1774-76 as part of the Portland Estate development by John White. The building is constructed of stock brick with a channelled stucco ground floor and features a slate roof. It stands four storeys high with a basement and has a three-window wide front that lacks classical detailing. To the right, there is a broad semicircular arched doorway with a panelled door and sidelights set in enriched jambs and a cornice doorhead, topped by a plain fanlight. The upper floors have recessed sash windows under flat gauged arches, and there is a plat band at the first floor level. The parapet has coping, and there is an early to mid 19th-century enriched cast iron balcony across the first floor, along with cast iron plumbed spike area railings.

Inside, the house boasts fine plasterwork ceilings in the Adam style in the front and back rooms on the first floor, featuring inset painted panels in roundel or oval shapes, fan motifs, and palmette and urn friezes, likely created by John Papworth. The interior also includes a top-lit stone geometrical staircase with a wrought iron balustrade featuring anthemion and lyre patterns, as well as statuary marble chimney-pieces and mahogany doors.
