St Andrew's House and Attached Coach House and Boundary Wall

This is a house, now used as architects' offices, along with an attached coach house and boundary wall. The main building was constructed around 1840 and remodelled in 1886 by Watson Fothergill of Nottingham for Dr Smart. It was later used as offices by TC Howitt and their successors from 1936. The house is built of red brick with blue brick and ashlar dressings, and has a timber-framed attic with roughcast infill. It features gabled and hipped roofs with two gable stacks. The exterior has a plinth and a first-floor band, with arched bargeboards to the gables. Most windows are segment-arched, margin-glazed sashes. The building is two storeys plus an attic, with two bays. The front facade on Mansfield Road includes a two-storey, three-light canted bay window with a hipped roof and flat-headed attic windows to the right, and a two-storey round tourelle with a spire roof and finial to the left. The centre of the Mansfield Road facade has two sash windows, with a single sash window above. The left return front, facing Mapperley Road, has a single-storey addition across its width, with a central timber-framed porch flanked by three-light composite sashes. There is an original panelled front door with sidelights, and a triangular bay window at the left end. The rear facade retains original segment-arched, multi-paned sashes. The attached coach house, dating from 1886, is two storeys high with a large gabled through-eaves dormer. The interior includes a stone spiral staircase dating from around 1840, and early 20th-century bathroom fittings. A boundary wall, constructed of brick with gabled brick coping, runs across both frontages.
