Description
Colby House is a 18th-century building located on Mill Street. It is two storeys high with an attic, constructed from red brick and topped with a slate roof. The house features an ogee bracket eaves cornice and has a slightly projecting centre with small whitened rusticated stone quoins, while larger quoins are found at the flanks of the house. There is a first-floor band and three near-flush frame sash windows that have flat arches, keystones, and eared architraves, with small corbels below the cills. The entrance is highlighted by a pedimented doorcase that includes a pulvinate frieze, flank consoles, and a broken fluted keystone. The door itself has fielded panels, including a lozenged lower panel. The upper front windows are missing glazing bars, while the renewed windows below do have glazing bars. The garden front features a two-storey splay bay, and the rear also has glazing bars. All the listed buildings in Mill Street are part of a group.
