Roundshaw is a housing estate and park in south Wallington and Beddington on the eastern edge of the London Borough of Sutton. Grid Ref . History Roundshaw was built on the site of the former Croydon Airport which once occupied the buildings of the first Croydon Aerodrome (originally named 'Plough Lane') which was demolished in 1928. The estate is commemorated in various ways; the naming of roads after aircraft, personalities, and firms linked with aviation to recall the airport's history: Mollison Drive, Lindbergh Road, Olley Close, Avro Way, Brabazon Avenue among other related aviation names. The name of the estate comes from Roundshaw Park on the edge of the site, named from a round 'shaw' or grove of trees. The estate accommodates approximately 1,800 homes. Construction began in 1965 with the first tenants moving in August 1967. The original brutalist pre-cast concrete flats and maisonettes were heated from a central communal boiler house. This was demolished during the regeneration of the estate and the newly refurbished homes incorporate their own energy-efficient modern heating systems. The London Borough of Sutton were the sole proprietors of the Roundshaw housing stock until 2007, when the responsibility was outsourced to Metropolitan and Hyde Housing Group who jointly created Roundshaw Homes. In 2015 the estate was transferred solely to Metropolitan. Regeneration During the mid 1980s and throughout the 1990s, major repairs and renovations of the concrete system dwellings were carried out by contracted specialists commissioned by the London Borough of Sutton, as the 1960s construction and build deteriorated which resulted in the cause of concrete cancer. The layout of the estate included underground garages and balcony passageways in which anti-social behaviour was commonplace. Due to the large spiraling costs generated by the ongoing repairs, the London Borough of Sutton began to formulate plans for a regeneration programme. After various consultations with the Roundshaw Residents Group, building contractors and various social housing groups, the problems were addressed of the original estate. Refurbishment trials began at Barnard Close and Shaw Way which were the only original 1960's concrete system blocks to be refurbished. This was carried out as a pilot scheme in the late 1980s and mid 1990s but this was not repeated throughout the rest of the estate, as it was not cost effective. Barnard Close is the only refurbished concrete system block still existing today. Shaw Way was subsequently demolished later at the final phase
