Knight Frank launches sale of 2.47-acre freehold site in prime south London location
Global property consultancy Knight Frank's London Land team has been appointed by AGS Property Investments (2015) Limited to market a substantial freehold Green Belt development opportunity located at 1 and 3 Metcalfe Avenue in Carshalton, with a guide price of £4.25 million.
07 January 2026
The 2.47-acre site falls under F1 (social and community use) providing potential for multiple uses including education, health facilities, or community halls and more, subject to necessary consents. The site comprises three buildings totalling approximately 19,814 sq ft (1,857 sq m) GIA and is available with full vacant possession from January 2026.
The property forms the final remaining parcel of the former Queen Mary's Hospital site, which underwent comprehensive redevelopment between 1998 and 2015.
Nick Alderman, Head of Central London Land at Knight Frank, said: "This is a rare opportunity to acquire an extensive freehold landholding in one of South London's most desirable suburban locations. The combination of significant acreage, excellent connectivity, and planning already in play makes this an attractive proposition for both institutional buyers and residential developers looking for strategic opportunities in an established area."
The site is situated in the heart of Carshalton, combining village charm with leafy parks, historic ponds, and a thriving high street, while maintaining a strong sense of community and access to excellent schools.
The property benefits from excellent transport links, with Carshalton Beeches station just five minutes' drive away, offering services to London Victoria in 30 minutes and to Blackfriars in 35 minutes via Thameslink. The site also enjoys strong road connections via the A232, A217, and A23, providing easy access to Croydon, Sutton, and the M25 for routes to both Gatwick (28 minutes) and Heathrow (50 minutes) airports.
