Clevedon House, 125-127 Castle Hill and 1 Coley Hill

Clevedon House is a terrace of three houses built in the 1850s or 1860s. Originally residential, the building was later converted into a school and is now used as flats.

The terrace is constructed of red brick laid in a Flemish bond pattern, with the basement level rendered. It features detailing in lighter and darker coloured bricks, stone window surrounds (likely including some reconstituted stone), a timber eaves cornice, and a hipped slate roof. The building has an L-shaped plan and extends over four storeys plus a basement.

The main four-bay elevation faces Castle Hill, while a secondary three-bay elevation faces Coley Hill to the west. The corners of the building are accented with quoins of buff and blue bricks, and a column of two-toned brickwork marks the original party wall between the two westernmost houses on the Castle Hill elevation. Two flights of steps, separated by a boundary wall and railings, lead to two front doors: a four-panelled door for 125 Castle Hill, and a modern door for 127 Castle Hill. A porch with a simple entablature supported on Doric columns and pilasters shelters both entrances. There are three windows at ground floor level, and four windows on each of the first, second, and third floors. All street-facing windows share a design consisting of a pair of sashes divided by a single moulded mullion. A bracketed timber eaves cornice is located just above the third-floor windows where the elevations meet the roof. The west elevation along Coley Hill also features mullioned windows on each of the ground, first, second, and third floors, with the ground-floor windows being the tallest. The southern elevation of this section is largely blank, except for two-toned brick quoins and a modern door at ground floor. The rear, southern, elevation faces onto Castle Hill and includes a variety of sash and mullion windows at all floor levels; a central column of three six-over-six sash windows illuminates a staircase, with three two-over-two sash windows located immediately to the east, and two additional six-over-six sash windows on the eastern side.
