1, SAVILE ROW W1 (See details for further address information)

Former house, now tailoring premises, built 1731-3 and ascribed to William Kent as part of Lord Burlington's estate. The building was extended between 1819 and 1836, refronted in 1870 by James Edmeston, and underwent alterations in 1881 and 1894 for the Royal Geographical Society. Subsequent alterations were made by Hawkes and Co as a tailoring premises in 1912.

The building is constructed of stucco-faced brick with a slate roof, rising to four storeys above a basement. The plan mirrors the angle of its corner site, with two principal rooms to the main body of the building separated by a former passage and a surviving staircase, with a gallery to the rear in a projection along Vigo Street. The Savile Row frontage is three windows wide, while the return to Vigo Street is long and irregular. A square piered composite capped porch of circa 1870 stands to the right, alongside a camber-arched wide display window in a moulded frame. An entablature runs over the ground floor. Upper floor windows are architraved with no glazing bars to the sashes. A string course incorporating cornices on consoles marks the first floor windows, with the cornices of the second floor windows acting as sills to the third floor windows. The building is topped by a crowning cornice and blocking course. Cast-iron grilles protect the first floor windows, and cast-iron area railings enclose the basement. Shop windows and a door of 1912 appear on the Vigo Street return.

The interior retains five original plaster ceilings with decoration, chimney pieces, and a stair compartment on the Vigo Street flank. This compartment features apsed ends finished with an enriched cornice, carved open strings, and enriched balusters, possibly altered in the 1790s. A 19th-century open-well stone stair is present elsewhere in the building. The Vigo Street wing was adapted by the Royal Geographical Society around 1870 as their map room. This room features an iron-balustraded gallery supported on fluted Ionic columns, with elaborate fluted columns on the gallery floor topped by foliate capitals. A high cove to the roof contains etched opaque glass beneath a trabeated ceiling. Taller Corinthian columns in the link to the rest of the shop complete this notable Victorian interior, which is considered complete and architecturally significant.
