No 4 Rock Terrace

No 4 Rock Terrace is the left house of a pair, built in the 19th century. It features painted stucco with a slate close-eaved roof and large brick end wall chimneys, each topped with 18 chimney pots. The facades are three storeys high and consist of two bays, with the stucco designed to resemble masonry. The roof includes skylights, and the windows are large hornless sash types: 16-pane on the second floor, 20-pane on the first floor, and 24-pane sashes in the outer bays of the ground floor. There is a small oculus to the right of the door of No 3. The inner bays have paired arched doorways set in a delicate timber trellis double porch, with the doorways featuring fluted pilasters, radiating fanlights (mock tracery on No 4), and doors with raised and fielded panels along with panelled reveals.

The forecourts are enclosed by dwarf stone walls and railings, with two gates in the centre and one at each end. The railings along the street have spear heads and urn standards, while the railings bounding the paths to the houses are of a different design, added in the 20th century, re-using railings from elsewhere.

The rear of the building is slate-hung and features canted two-storey bays on each side with 16-pane sashes above. There are two central first-floor round-headed windows over doors in 20th-century or renewed trellis porches, and a large overhanging addition at the centre of the third floor, which has four windows and a hipped slate roof.
