Redbridge · housing and retrofit

Ilford grew rapidly around 1900: its population rose from about 11,000 in 1891 to almost 80,000 in 1911. Much of this growth was long, regular streets of two-storey terraces, including the Grange, Downshall and Mayfield estates.

The Aldersbrook Estate is Edwardian, with red brick, slate roofs and sliding sashes, while Barkingside, Clayhall and Gants Hill have interwar semis and bungalows. Woodford has Georgian, Victorian, Arts and Crafts and large interwar houses.

Local considerations

What tends to shape retrofit here

  • Narrow-frontage terraces with rear outriggers create junctions where condensation risk should be checked
  • Original sash windows in conservation areas favour secondary glazing
  • Redbridge has 16 conservation areas, with Article 4 directions in some
  • Interwar homes usually have cavity walls to check before filling

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