We live in Sutton Ecology Centre (https://www.sutton.gov.uk/info/200453/parks_trees_and_open_spaces/.../3 ).Carshalton has a good community atmosphere, with cafes, library, sports centre etc, a river, ponds and open spaces, and it is close to central London. In the community-owned arts centre there are frequent music nights and concerts (see https://cryerarts.co.uk/) .
The Barn is modernised with a home cinema, a well-equipped kitchen and a jacuzzi bathtub in the family bathroom.
It takes just 28 minutes to reach the city centre by train, and the station is a 5 - 10 minute walk from our home. Direct trains to Victoria, Blackfriars or Waterloo stations get you to big free art museums like the Tate Britain, Tate Modern, the South Bank, and the South Kensington museums - as well as theatres, and much else - in less than an hour.
Carshalton makes a pleasant contrast with central London, and we have several artist friends living nearby (see https://www.carshaltonartists.com ) The High Street is 5 minutes walk away, with friendly pubs and cafes, the old church has a 13th C Lady Chapel, and there is an excellent local history museum and outdoor cafe/bar less than 30 seconds away !
