Description
No. 78 Mount Street is a corner terrace house built in 1896-97 by Balfour and Turner, and it is nearly identical to their No. 6 Aldford Street. The building is constructed of red brick with Portland stone dressings and features a slate roof. It showcases a Free Style Queen Anne design with some Jacobethan details. The house has five storeys and a basement, with two unequal window bays.
On the left side, there is a recessed porch with an elliptical arch supported by broad squat stone piers. The right-hand pier overlaps the two-window ground floor bay, which has a central dividing pilaster. The canted oriel window, featuring four narrow sash lights with architraves, is corbelled out and topped with a cornice that serves as a balcony for the second-floor tripartite stone-dressed window, with similar windows aligned above. The entrance bay has narrower coupled and single stone-dressed sash windows on the second to fourth floors.
The front of the building is finished with a stone-coped parapet that is raised to form a gable over the larger right-hand bay. The return side has two large corbelled chimney stacks connected by wide segmental arches, with balconies on the ground and first floors. The fenestration is irregular, featuring a small oriel window adjacent to the chimney stack on the first floor. The area is enclosed by cast iron Arts and Crafts railings that return with a screen wall to the garden, connecting with those of No. 67 Aldford Street. This building is part of an island block development by Balfour and Turner, contributing to the Grosvenor Estate improvements.
