Planning in Ealing

Local planning rules for loft conversions in Ealing.

Ealing's conservation areas include Bedford Park (Britain's first garden suburb), Ealing Green, Hanger Hill Garden Estate, Northfields, Acton Park and Walpole. Article 4 directions cover Bedford Park and parts of Hanger Hill. The council favours mansard lofts and rear-only dormers in conservation areas; full-width rear extensions need careful design.

We tell you whether your loft conversion is permitted development, prior approval, or full planning before you sign anything.
