Planning in Ealing

Ealing has a strong SPD for extensions. Conservation areas in Bedford Park, Pitshanger and Ealing Green require design that respects the Arts & Crafts idiom.

Party Wall Act — what to expect

Mixed — semis in the west, terraces in Acton mean two party walls.

Typical costs in Ealing

For a mid-spec 25 m² kitchen extension, all-in (professional fees, planning, party wall, VAT and 12% contingency), expect roughly £105,000 to £160,000. High-spec finishes, structural glazing or a full basement dig-out will push above the top of this range; a smaller side-return can come in under the bottom.
