Description

Two attached town houses, built around the 1870s in Liskeard. They are constructed of polychrome masonry with a granite ashlar plinth, rubble stonework, dressed freestone, and patterned tiles. Number 21, on the left, is colour-washed. The roofs are of rag slate, with wide eaves at the front supported by console brackets, and moulded iron gutters. The buildings follow a double-depth plan, with a deep wing extending to the rear of the left-hand property.

The two houses have two storeys and a five-window front. Number 21 has a symmetrical three-window facade with a central doorway, whilst Number 19 has a two-window front with a doorway on its left-hand side. The first-floor windows have segmental heads with round-headed keystones that rise under linked, moulded hoodmoulds. They contain four-pane sash windows with hornless glazing, set onto a moulded sill string with brackets supporting a tiled frieze. The ground-floor windows are similarly arched, with linked hoodmoulds that apex over the doorways, featuring nook shafts to the jambs, traceried stone heads as overlights, and six-panel hornless sash windows. The doorways themselves have shouldered-headed lights and carved tympanae.

The interior of the properties has not been inspected.
