79, Mount Street W1

No. 79 Mount Street is a terrace house built between 1892 and 1894 by Balfour and Turner. It features red brick with Portland stone dressings and a slate roof, showcasing a Free Style Queen Anne design that is a restrained variant of No. 5 Aldford Street. The building has four storeys, a basement, and gabled attics, and is three windows wide. The entrance is located in an enclosed porch with a semicircular arched opening that includes three orders of mouldings, slender jamb shafts, imposts, and stepped voussoirs.

Above the entrance, there is a narrow canted bay extending three storeys, balanced on the left by a similar canted bay supported by octagonal stone columns with Byzantine-style foliated caps, positioned in front of a ground floor window. The narrow central section features a single sash window on each floor, which matches the sashes of the canted bays, while the outer flanks are blind. All windows have glazing bars and shallow architraves. A crisply profiled stone string course runs over the ground floor, and a stone entablature is carved above the third floor around the bays, which extend into the attic and are finished with plain gables. A dormer is situated in the centre above a short link section of the parapet. The property is also adorned with Arts and Crafts cast iron area railings. This house is part of an island block development by Balfour and Turner, contributing to their improvements of the Grosvenor Estate.
