75, Harley Street W1

No. 75 Harley Street is a terraced town house built around 1773-74 as part of the Portland Estate development by John White, in collaboration with the plasterer Thomas Collins, who were associates of the architect Robert Adam. 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 a dormered mansard, and has three windows across its façade.

The entrance is marked by a semicircular arched doorway on the left, which includes a panelled door, sidelights, and a fanlight in a Venetian style. The upper floors have recessed sash windows set under flat gauged arches. The stuccowork is finished with a plat band at the first-floor level, and there is a parapet with stone coping. A cast iron balcony with an anthemion pattern spans the first floor, complemented by cast iron area railings.

Inside, the house boasts a fine interior featuring a top-lit geometrical stone staircase with a wrought iron balustrade. The ceilings are adorned with delicate plasterwork, friezes, and stucco mythological overmantel medallions. Additional highlights include inlaid marble pilastered fireplaces and mahogany doors.
