Mostly detached housing, with some semi-detached, on the north side of Twentywell Lane (formerly Twentywellsick Lane - the 'sick' placename element referring to an adjoining stream). Some housing is shown on the 1935 25" OS map, the rest has been built by the time of the 1958 edition. The development plot was taken from the Beauchief Park estate (HSY2253). The 19th century OS maps show the land as predominantly fields, which were part of the piecemeal enclosure around Beauchief Hall (HSY2255) described by W. Fairbank in his survey of the estate in 1759-61 (studied by Smith 1990). Prior to this, the land is assumed to have been in agricultural use for the monastic community at Beauchief Abbey (HSY2254). Legibility is invisible as no earlier landscape features were fossilised within this housing development.
