No 9 And Attached Rear Walls And Outhouse

This is a substantial house, built between 1723 and 1728 for James Brydges, Duke of Chandos. It was designed by Benjamin Holloway or Fort and Shepherd, who were the Duke's surveyors in London. The house is constructed of Flemish-bond Bridgwater brick with red headers and yellow stretchers, featuring painted stone details for the cornice, architraves, doorcase, and hood, and a plain tile roof with brick stacks incorporated into the party walls. It is arranged as a double-depth plan with three storeys and basements, presenting a symmetrical five-window facade.

The moulded coping to the rebuilt parapet sweeps upwards to the right to join with the neighbouring property at number 11. Brick platbands delineate the floors, while the windows have cyma-moulded segmental-arched architraves with moulded cills and brackets, housing 6/6-pane sash windows, some of which have crown glass. The front door is a 20th-century addition, consisting of six panels within a cyma-moulded architrave with a moulded cornice and brackets.

The rear of the house was extended around 1840, and the accompanying brick rear wall demonstrates a careful use of flat gauged brick arches. The second floor has 3/3-pane sash windows, while a 6/6-pane tripartite sash window on the first floor opens onto a wrought and cast-iron balcony. A back door features six beaded panels.

The interior displays a variety of periods and detailing. The outer hall is panelled below a dado rail and features a late 19th-century door with coloured margin-paned glass. A room to the right has full-height raised-and-fielded panelling with a wide dado rail and cyma-moulded cornice, though some panelling has been removed from the rear wall. A simple stone fire surround has curved inner corners. A semicircular archway leads to the rear stair hall, which incorporates raised-and-fielded panelling below the dado rail and a late 18th-century staircase with an open string, stick balusters, a mahogany handrail, and panelled newel posts. Rooms on the first floor at the rear are typical of the early to mid-19th century; one features a white marble fire surround with reeded lintel and jambs and blocks to the corners, while the door architraves have similar detailing with fasces to the lintel and jambs, and patera to the corner blocks. A room to the rear left contains a semi-elliptical arch marking the former rear wall, and a 10/10-pane sash window in the 1840s wall. The front room on the first floor has a cupboard door with two raised-and-fielded panels flanking the chimney breast. A room on the second floor to the right retains wide pine floorboards and a planked door with wrought-iron strap hinges.

The property includes a tall, approximately 3-meter-high Flemish-bond brick wall enclosing a garden of around 20 meters square. Attached to the left is a mid-19th-century two-story service block with 8/8-pane sash windows. The houses in Castle Street collectively represent an unusual group, notable for their scale and ambition outside of London’s West End.
