Planning in Camden

Camden's conservation-area coverage is heavy in Hampstead, Primrose Hill and Fitzrovia. Rear extensions to 3m PD are often possible outside these zones but the planners scrutinise glazing and roof form closely.

Party Wall Act — what to expect

Terraces mean two Party Wall Awards on almost every project.

Typical costs in Camden

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.
