Croydon · housing and retrofit

Croydon’s housing ranges from Victorian streets near the town centre to extensive interwar and post-war suburbs. In Purley, the Webb Estate was developed by William Webb from 1888, with building starting in 1898 – individually designed houses on generous, hedged plots that reflected his “garden first” approach.

New Addington began in the 1930s as a garden village promoted by the First National Housing Trust, and was completed as a large estate after the Second World War, with the Fieldway estate added later.

Local considerations

What tends to shape retrofit here

  • The Webb Estate and Upper Woodcote Village are conservation areas, so external changes attract scrutiny
  • Bradmore Green in Coulsdon is one of the borough’s older conservation areas
  • Post-war estate homes should have their construction type confirmed before wall insulation is chosen
  • Large detached houses typically have high heat loss, so room-by-room calculations are worthwhile

Conservation area rules, Article 4 directions and listed building controls are set by Croydon Council and can change. Check the current position before finalising external changes: Croydon conservation areas.
