31, Queen Anne Street W1

31 Queen Anne Street is a terraced town house built in the 1760s, with some alterations from the early to mid-19th century. It is part of the Portland Estate development. The building is stuccoed, featuring a channelled ground floor and a slate roof. It has four storeys and a dormered mansard above a basement, with three windows across the front.

The entrance includes a semicircular arched doorway flanked by pilastered side lights and a fanlight, topped with a cornice raised in a pediment. The windows are recessed sashes beneath flat gauged arches with architraves, and the first-floor windows have consoled pediments and enriched friezes. There is a plat band at the first floor and a bracketed cornice over the second floor, along with a parapet that has coping. The first floor features late 19th-century cast iron bowed balconettes, and there are cast iron plumbed spike area railings. The interior has not been inspected.
