Description

Copner House is a town house, now used as offices, dating from the mid to late 18th century with alterations from the mid 19th century. The building is constructed of brick with a stuccoed front and features a slate roof with gabled dormers. It has a double-depth layout with a carriageway through the front range at the south end.

The exterior consists of two storeys and an attic, with the front having been remodelled in the mid 19th century and featuring four bays. There is a sill band at the first-floor sill level and a moulded eaves board with a decorative scalloped edge. The entrance doorway is located in the second bay from the left and has a moulded architrave and a six-panel door. At the right-hand end, there is a carriageway with a segmental arch and panelled double doors. On either side of the entrance doorway are plain horned sash windows, and on the first floor, there are four similar, shorter sash windows, all set in openings with wide, moulded architraves. The building also has two gabled dormers with moulded barge boards and apex finials, each containing a sash window with glazing bars arranged in a 3x2 pane configuration.

The rear elevation features a central doorway with a flat arched head made of five raised-and-stepped voussoirs. On each side of the doorway is a Venetian window with a raised-and-stepped keystone in the arch; the left-hand window has a central sash with intersecting glazing bars and narrow side sashes, while the right-hand window was altered in the 20th century to include French doors with sidelights. On the first floor, there are two similar Venetian windows with raised-and-stepped keystones in the arches and original sashes with intersecting glazing bars.

The Copner family lived in the house from 1870 until 1938, when it was converted into offices. The interior has not been inspected.
