Barnet · housing and retrofit
Barnet is one of London’s largest boroughs by population. Much of its housing consists of interwar semi-detached and terraced houses in areas such as Finchley, Mill Hill and Edgware, with Victorian and Edwardian housing in parts of the borough and post-war and new-build flats.
It also contains Hampstead Garden Suburb, where the Hampstead Garden Suburb Trust operates a Scheme of Management. Owners need the Trust’s consent for many external alterations, in addition to planning permission where required.

Local considerations
What tends to shape retrofit here
- Properties in Hampstead Garden Suburb need Trust consent for many external changes
- Interwar cavity walls should be checked for condition and any previous fill
- Bay windows and hipped roofs create junctions that need attention
- Larger detached and semi-detached houses have more exposed wall and roof area than terraces
Planning rules, conservation area guidance and Article 4 directions are set by the local planning authority and can change. Check the current position with Barnet Council before finalising external changes.
