Copley Dene and Wall Attached to Left

Copley Dene is a house dating from the early to mid-18th century, with later alterations and additions. It is constructed of red brick and features hipped red plain tile double range roofs with end chimney stacks. The building has two storeys and attics, with stone coping to the parapet and a brick band underneath. The facade is symmetrical, showcasing two two-storey, three-light angled bays. The windows are small paned vertically sliding sashes with gauged brick arches, and there is a small paned vertically sliding sash with a moulded brick lugged surround and keystone above the central doorway. This doorway is framed by timber pilasters with moulded capitals and bases, a frieze, dentilled soffits to the moulded pediment, and reveal panels. The door itself is a 20th-century part glazed design. The attic features three 20th-century lights.

To the right of the main house is a two-storey, two-bay extension with a flat-headed archway that connects to the original structure. On the left, a red brick wall with moulded capping forms a semi-circle to the southwest of the house. There is a similar wall, now unattached, to the northwest.

Inside, the house includes ground and first-floor panelled rooms, with a ground floor fireplace featuring fluted side columns and a first-floor fireplace with pilasters. The ceilings have moulded cornices, and there are moulded architraves on six-panelled doors, one of which has a fluted surround and a semi-circular fanlight above. The rear room contains a marble fireplace with fluted columns, along with several other 18th and 19th-century fireplaces. Most windows have panelled shutters, and there is a moulded arch on the landing. The open well staircase features a wreathed handrail, two moulded balusters on each tread, and mouldings on the open treads.
