16, CLIFTON HILL (See details for further address information)

These are two linked pairs of large semi-detached villas, likely built in the early 1840s. Number 16, Clifton Hill, was extended on the south side in 1909. The substantial principal walls are constructed of rammed chalk with a painted render finish, designed to imitate ashlar masonry. The roofs are slate, with brick chimney stacks, and the 1909 extension is tile-hung.

The buildings are five storeys high, including a raised basement, two main floors, and two attic floors built into the steeply pitched roofs. The principal facades are symmetrical, with two bays each. The pairs of houses are connected by a recessed two-storey, two-bay section that provides entrances to numbers 3 and 4, Clifton Road, while numbers 5 and 16, Clifton Hill, have entrances in set-back two-storey wings. The internal layout is mirrored between each pair, with a central staircase leading to large front and rear rooms.

The front elevations are gabled and symmetrical, featuring two windows in the lower attic storey and one in the higher. Square bay windows with moulded cornices and crenellated parapets extend from the basement and ground floors. Square drip moulds are placed above the upper floor windows. Timber sash windows are present throughout, with tripartite lights on the ground and first floors having 4-over-4 panes to the central sash and 2-over-2 panes to the margin lights. Upper floor windows have 3-over-3 panes. The rear elevations have a similar fenestration pattern but lack bays and drip moulds; ground and first floors have 6-over-6 sashes. Round-headed windows and doors feature in the entrance bays, along with timber panelled doors and plain fanlights. The roofs are steeply pitched with pierced bargeboards along the gable eaves. The Edwardian extension to number 16 also features a basement and two storeys, with square bay windows having timber casements and glazing bars to the upper lights.

Internally, the buildings retain their original plan, much Victorian joinery, and a variety of original and later fittings. Elegant staircases with square balusters and mahogany handrails are present, though the staircase in number 16 was replaced after fire damage.

The houses were likely constructed shortly after the arrival of the London and South Western Railway between 1839 and 1840, possibly utilizing chalk spoil from a nearby railway cutting.

These villas are of special architectural interest as well-preserved early-Victorian villas in a striking picturesque style, and for their unique construction. The extensive use of rammed chalk is unusual, and these may be the tallest examples of this technique in the country. They occupy a prominent hillside overlooking the city and serve as notable landmarks.
