29, Harley Street

No. 29 Harley Street is a house built in 1911 by Sidney Thtchell for Leslie Paton, with a library added in 1919 by C.F.A. Voysey. It is a building of group value. The exterior is faced with ashlar, and the roof is obscured. The house has four storeys, a basement, and attics, and is three bays wide. An entrance is on the right-hand side at ground floor level, flanked by console brackets; these, along with a bracket to the left, support a geometric iron balcony to the first floor. A canted bay window is to the left, with small-paned timber casements and fixed or top-hung lights above a dentil transome. Double-leaved glazed mahogany doors are set beneath a glazed overlight. The first floor has a tall storey with small-paned windows presented as French windows with fixed lights above, each set within a moulded stone architrave beneath a bay-leaf frieze under a shallow bracketed canopy. The second floor has similar casements within moulded stone architraves and shallow cornices, above a pulvinated frieze; the windows are set forward slightly. A moulded band runs at the level of the upper floor storey. Small-paned casements are set between vertically arranged garlands. A continuous moulded band stretches above, articulated across the bays, followed by a modillion cornice. A balustraded parapet follows the rhythm of the facade. Three gabled dormers with small-paned casements are present. Party wall brick stacks are visible.

The interior remains largely unaltered, offering an unaltered example of an early 19th-century townhouse, and of particular note is the Voysey library. A window has been redesigned to accommodate a lowered ceiling. The library features opaque glass, typical of the Arts and Crafts movement, alongside original fittings. Mahogany joinery was incorporated to suit existing work, including bookcases, cupboards, and a desk, fitting three sides of the room and designed to align with an existing fireplace. Original Voysey door furniture and metalwork have been retained. A first-floor drawing room contains a timber fireplace, overmantel, bookshelves, and a decorative frieze. Single and double-leaf mahogany doors are of high-quality timber construction. The ground-floor dining room is oak panelled, with typical plasterwork to the ceiling and walls. A mahogany stair has square newels, turned balusters, and original red lacquer work to the skirtings and dado rails. The building represents a rare survival of an unaltered Voysey interior within an existing structure.
