Planning in Haringey

Haringey is generally receptive to modest ground-floor extensions but the Crouch End and Muswell Hill conservation areas add design scrutiny. Front elevations are protected.

Party Wall Act — what to expect

Ladder-street terraces almost always trigger two party wall notices.

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

Typical costs in Haringey

For a mid-spec 25 m² kitchen extension, all-in (professional fees, planning, party wall, VAT and 12% contingency), expect roughly £115,000 to £170,000. 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.
