Planning in Hackney

Hackney has stringent design guidance, especially around the many conservation areas (De Beauvoir, Clapton Common, Stoke Newington). Contemporary detailing is welcomed if it's sensitive to the terrace rhythm.

Party Wall Act — what to expect

Almost every project needs two Party Wall Awards. Neighbours here are experienced — expect them to appoint their own surveyor.

Read the Party Wall etc. Act 1996 guide for full detail on notices, timelines and surveyor costs.

Typical costs in Hackney

For a mid-spec 25 m² kitchen extension, all-in (professional fees, planning, party wall, VAT and 12% contingency), expect roughly £120,000 to £180,000. 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.
