Planning in Hammersmith & Fulham

H&F has a tightened basement policy since 2018 — feasibility on any dig-out needs early consultation. Conservation areas (Brackenbury, Hurlingham) are extensive.

Party Wall Act — what to expect

Terraces + basement work = complex, often three-party party wall proceedings.

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

Typical costs in Hammersmith & Fulham

For a mid-spec 25 m² kitchen extension, all-in (professional fees, planning, party wall, VAT and 12% contingency), expect roughly £130,000 to £195,000. 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.
