40 Devonshire Street

40 Devonshire Street is a town house built around 1910, featuring red brick with stone dressings and a tiled roof in the Arts and Crafts Georgian Revival style. The building has two storeys and an attic beneath a pyramidal roof, with a width of four windows. The doorway is located to the left and is flanked by two main ground floor windows set in arcaded openings, which have keystones and are linked by a bold stone impost string. The door is recessed within a stone eared bolection architrave, topped with a cornice and a fanlight above that has radial glazing. A small side window to the left of the doorway disrupts the symmetry. All windows are recessed sashes; those on the first floor are positioned above the spandrels of the ground floor arcade and feature louvred shutters. The reveals of these windows extend up to the soffit of the leaded trough gutter, and there are four half-dormers that break through the eaves. The house stands on a tall stone plinth that extends to the front and has been refaced in marble to create planting boxes. This plinth returns as "skirting" along the mews flank, which includes a slightly projecting bold chimney breast with a panelled stack, as well as basement openings and a circular ground floor window. The first floor features two sashes and a dormer, while the rear has a canted bay. This building is part of an early 20th-century effort by the Portland Estate to restore the domestic character of the area, which had become overly professional.
