12, Buckingham Street WC2

Number 12 Buckingham Street is a terraced town house built around 1676-77, with early 19th century and later alterations. It is part of Barbon's development of the York House estate. The building features a stucco-faced brick exterior with a concealed roof and stands three storeys high, plus a rebuilt attic storey, with six windows across the front. The ground floor is rusticated, and the doorway is located in the second bay from the left, featuring a panelled door and fanlight set within an enriched carved wood architrave. The windows are recessed glazing bar sashes in exposed box frames, and there are plat bands above the ground and first floors. The parapet has coping, and there are cast iron area railings with urn finials.

Inside, the interior has been significantly altered in the early 19th century and later, but it retains a good staircase off the bolection panelled inner hall. The staircase is substantially constructed of oak, featuring a dog-legged design with moulded closed strings, twisted balusters, a moulded handrail, and solid square newels with turned pendants. The landings are panelled, with panelled pilaster archivolt arched doorcases, impost strings, and moulded cornices. A plaque from the London County Council notes that Samuel Pepys resided here from 1679 to 1688, living with William Hewer when the house was partly used as the Admiralty Office. The building is graded I due to its association with Pepys.
