18, Buckingham Street Wc2

No. 18 Buckingham Street is a terrace town house built between 1675 and 1676, with early 18th century remodelling. The facade was rebuilt in a replica style between 1960 and 1966 and is part of Barbon's development of the York House estate. The building features a brown brick exterior with red brick dressings and a slate roof. It has four storeys, a basement, and a dormered mansard roof.

The facade is three windows wide, flanked by giant quoin pilasters. To the right is a doorway with a panelled door and delicate late 18th century radial ironwork in the fanlight, set within a fine early 18th century wood doorcase that includes panelled reveals and soffit, fluted Corinthian pilasters, and an architrave frieze that is broken over the capitals. Elaborately pierced and carved console brackets support a large cornice-hood, which also has a panelled soffit. The windows are recessed glazing bar sashes in exposed box frames, set under segmental red brick arches, with deep red brick dressings on each floor. The first floor windows feature raised brick aprons.

Additional architectural details include a brick gauged plat band over the ground floor, a moulded brick string as a sill course to the second floor, and a stone cornice below the attic storey. The parapet has coping, and there are wrought iron area railings with pommel-vase finials and decorative scrollwork flanking the doorway, which includes link extinguishers.

Inside, alterations and rebuilding have preserved or reset some of the fielded panelling and moulded cornices, as well as the fluted Doric pilaster hall screen. The fine staircase features cut and carved strings, a panelled soffit, three twisted balusters per tread, Corinthian column newels, and a moulded handrail that sweeps over them.
