49 and 51, Frognal

49 and 51 Frognal are a pair of semi-detached houses built in 1886 by Sir Reginald Blomfield, with No. 51 constructed for himself and No. 49 for T.J. Cobden-Sanderson, an Arts and Crafts bookbinder. The houses are made of red brick and feature slated roofs with hipped dormers, projecting eaves supported by a central bracket, tall slab chimney-stacks, and gables on the outer bays. They are two storeys high, with attics and semi-basements. Each house has three windows plus one window in recessed entrance bays. The doorways have bracketed hoods and panelled part-glazed doors, which are accessed by steps. The windows have gauged red flat brick arches and the outer bays are tripartite, with the attics featuring blind lunettes above the central windows. The ground floor inner bays are also tripartite and have cornices. The first-floor sashes are fitted with louvred shutters. No. 51 has a late 20th-century basement garage and a tripartite bay window on the ground floor. The gables have moulded timber soffits that return inwards for a short length at the bases, creating the appearance of broken pediments. The interiors have not been inspected.
