6, Aldford Street W1

No. 6 Aldford Street is a corner terrace house built between 1896 and 1897 by Balfour and Turner. It features red brick with Portland stone dressings and a slate roof, showcasing a free style Queen Anne design with some Jacobethan details. The building stands five storeys tall with a basement and has a slightly asymmetrical arrangement of two window bays.

To the right, there is a stone corniced porch with a depressed moulded arched entrance. The porch's stonework integrates with the face of a half-canted stone bay to the left, which has two architraved sash lights on the front. The canted bay is fully developed on the first floor, featuring a similar pair of sash lights on the front and one on each side. The upper floors have pairs of similar windows that are stone-dressed with architraves, along with narrower coupled and single lights to the right.

The front of the building is topped with a parapet and a stone-coped gable over the major left-hand bay. The return elevation displays two large corbelled external chimney stacks linked by wide segmental arches, which have balconies on the ground and first floors. The fenestration is irregular, including a small oriel window butting against the stack on the first floor. The rear elevation is gabled, and a stone-coped screen wall with wrought iron area railings connects to those of the similarly designed No. 78 Mount Street. This house is part of an island block development by Balfour and Turner as part of their improvements to the Grosvenor Estate.
