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.

Typical costs in Haringey
For a mid-spec 25 m² rear dormer loft conversion, all-in (structural design, building control, party wall, VAT and 12% contingency), expect roughly £115,000 to £170,000. A mansard, a hip-to-gable with high-spec en-suite joinery or a conservation-area application will push above the top of this range; a self-built rooflight conversion comes in well under the bottom.
