115a, Harley Street W1

No. 115A Harley Street is a town house facing Devonshire Street, built around 1905, possibly by Elgood or Tatchell. It features red brick with stone dressings and a tiled roof, designed in the Queen Anne style. The building has two storeys, a basement, and a dormered attic, with a three-window centre and slightly advanced pediment-gabled wings, each containing two windows on the first floor and a rectangular bay on the ground floor.

The off-centre doorway is flanked by short engaged columns and has enriched console-brackets supporting a semicircular hood. To the right of the doorway is a tripartite flush framed glazing bar sash window with a pulvinated cornice. The first floor has three evenly spaced flush framed glazing bar sashes set under segmental keystoned arches, with apron panels beneath, and three corniced dormers above. The rectangular bay windows in the wings also have tripartite sashes, and the first floor windows match those in the centre. The pediment-gables feature three-light lunettes with voussoirs and keystones. The property is enclosed by Queen Anne style cast iron area railings.

This house is part of an early 20th-century effort by the Portland Estate to restore the domestic character of the area, which had become too professional. Notably, it was the residence of the playwright Sir Arthur Pinero from 1909 until his death in 1934, commemorated by a plaque from the Greater London Council.
