Crouch End is Victorian and Edwardian terraces and villas around the Broadway, Crescent Road and the Haringey Ladder, with large Victorian houses on the Highgate side. Side-return and wraparound kitchen extensions dominate in Crouch End, along with lower-ground conversions where houses step down the hill.
The Crouch End Conservation Area covers the Broadway and many surrounding streets, so dormers there need planning permission from Haringey Council. Most Crouch End extensions we price fall between £2,500 and £4,000 per m², so a 25–30 m² kitchen extension is roughly £75,000–£120,000 fitted out; our house extension cost guide breaks the numbers down. We check permitted development rights at the first visit and deal with Haringey Council in-house.

Loft conversions in Crouch End
Crouch End roofs suit rear dormers and L-shaped dormers; within the conservation area a dormer needs planning permission, and Haringey's appraisal discourages front dormers where they are not part of the street.
Expect £45,000–£75,000 for a dormer loft with a bedroom and en-suite, £60,000–£100,000+ for a mansard and from £25,000 for a Velux conversion; the loft conversion cost guide has the breakdown. For a Crouch End loft we measure head height, roof structure and the stair landing first, and the quote includes structural calculations and Building Regulations approval.
Renovations and refurbishment in Crouch End
Crouch End renovations are typically complete refurbishments of Edwardian houses and conversions of large houses into well-planned family homes.

See our renovation cost guide for realistic budgets. Crouch End projects are run by a single project manager under a JCT contract, with a written specification and a 10-year workmanship warranty.

Common questions about building in Crouch End
Do I need planning permission for an extension in Crouch End?
Houses (not flats or maisonettes) keep national permitted development rights for a single-storey rear extension of 3m attached or 4m detached, up to 6m or 8m through prior approval, and for most rear dormers within 40 cubic metres on a terrace or 50 on other houses. Haringey Council's Crouch End, Hillfield, Stroud Green and Hornsey High Street conservation areas cover parts of N8. Single-storey rear rights remain there, but side extensions, two-storey rear extensions, cladding and roof additions such as dormers need permission. The Crouch End Conservation Area has no Article 4 direction. Our permitted development guide sets out the limits.
What does Haringey Council expect for loft conversions in Crouch End?
Inside the Crouch End Conservation Area a dormer is not permitted development, so it needs a planning application to Haringey Council. The Crouch End Conservation Area Character Appraisal says new or enlarged front dormers should be avoided where they are not part of the street's character, and rear dormers need care where the backs of houses can be seen from nearby streets. Outside the conservation areas, a rear dormer within the national volume limits can usually go ahead as permitted development, subject to the usual conditions.
What does a side return extension cost in Crouch End?
Crouch End's Victorian and Edwardian terraces are well suited to side return extensions, which typically cost £65,000–£130,000 at mid to high specification, including VAT. The range reflects the length of the infill, the glazing and the kitchen fitted. Our Victorian side return extension cost guide sets out what is included. In the conservation area a side extension is not permitted development, so allow for a planning application there.
