58, Queen Anne Street W1

No. 58 Queen Anne Street is a terraced town house built in the 1760s, with alterations made around 1840 to 1850 as part of the Portland Estate development. The building features stock brick construction with a channelled stucco ground floor and a slate roof. It stands four storeys tall, including an attic, and is three windows wide.

The entrance is marked by a semicircular arched doorway on the left, which has a keystone and a later 19th-century door, along with side lights and a fanlight adorned with wrought iron grilles. The windows are recessed glazing bar sashes, with keystones on the ground floor and architraves on the upper floors. The first floor windows have consoled pediments, while the second floor features eared architraves, and the attic storey windows are segmental headed with curved cornices. A plat band runs above the ground floor stuccowork, and there is a painted stone bracketed cornice over the second floor, topped by a parapet with coping.

The first floor includes an early 19th-century balcony with anthemion patterned rails. Wrought iron area railings with flambé urn finials add to the exterior detail. Inside, there is some original plasterwork, a geometrical staircase with a wrought iron balustrade, and various chimneypieces. A plaque from the Greater London Council commemorates the residence of composer Hector Berlioz here in 1851.
