11, 11a and 15-23 (Odd)

A terrace of seven houses on Castle Street in Liskeard, dating to the early 19th century. The group comprises two houses of three bays and five houses of two bays, with the final house, No. 11, having a stretched two-bay front positioned either side of the door. All buildings are two storeys with basements to the rear.

The exterior of all buildings is rendered stucco with a low and modestly projecting plinth. No. 11 is distinguished by rusticated pilasters and a string course. The return elevation of No. 11 is also stuccoed and features a four-over-eight horned sash window with glazing bars at basement level, a later projecting canted bay window at ground floor (above a basement at street level) with a mullion and transom window at the first floor, also of later date. All houses have stucco stacks positioned above the party walls. Nos. 11, 15, 17 and 23 have asbestos cement tiled roofs, while Nos. 19 and 21 retain their original natural Cornish slate. All but one house (No. 17) are provided with Doric door cases featuring engaged columns and entablatures, some with dentils. All doors are four-panelled, except No. 19, and some have top glazing.

Fenestration varies across the terrace. No. 11 has modern double-glazed timber sashes of Edwardian type, horned with two-over-two pane configuration. Nos. 11A to 21 have timber sashes without glazing bars, while No. 23 has timber sashes with glazing bars. Rear elevations are constructed of stone rubble with natural slate hanging and feature irregular modern timber casement windows without glazing bars. Nos. 11A to 19 have lavatory extensions.

The interior plans are of double depth. Nos. 11A, 15, 17 and 19 are configured with the entrance and stair hall positioned to the right, reception room to the left, and rear room and stairs beyond. No. 23 is handed the opposite way and has two windows to the front reception room. Nos. 21 and 11 are arranged with two reception rooms to the front, each side of the entrance and stair hall.

The interior of No. 23, which was available for inspection, is plain but good quality, featuring a stair with hardwood swept handrail and stick balusters, and plain doors with recessed panelling and simple architraves. The other house interiors were not inspected but are understood to be of similar finish. The building to the rear of No. 11 on Castle Hill, of later construction and much altered, does not form part of the listed building.
