Merton · housing and retrofit
Part of the London County Council’s St Helier estate, built between 1928 and 1936 as a large cottage estate, lies in Merton around Morden; the rest is in Sutton. Merton Park, laid out by John Innes from the late 19th century, developed as a garden suburb with Arts and Crafts houses.
The borough also includes the Victorian and Edwardian streets of Wimbledon and Mitcham, and estates currently being regenerated.

Local considerations
What tends to shape retrofit here
- St Helier’s repeat house types suit batch assessment and coordination for landlords
- The John Innes Merton Park and Wilton Crescent conservation areas have Article 4 directions
- Victorian and Edwardian terraces are likely to have solid walls and suspended timber floors
- Check Article 4 controls before external insulation or window replacement
Conservation area rules, Article 4 directions and listed building controls are set by Merton Council and can change. Check the current position before finalising external changes: Merton conservation areas.
