Muswell Hill is Edwardian houses built by Collins and other Edwardian developers around the Broadway, Fortis Green and Queens Avenue, with Arts and Crafts houses towards Highgate. Side-return and wraparound kitchen extensions on the Edwardian houses are the typical Muswell Hill project; the houses are wide, so full-width kitchen-family rooms work well.
Budget guidance for Muswell Hill: expect £2,500–£4,000 per m² for a single-storey extension, which puts a 25–30 m² kitchen extension at £75,000–£120,000; two-storey and wraparound schemes are priced on the structure involved (see our house extension cost guide). The Muswell Hill and Fortis Green conservation areas cover parts of N10, so dormers there need planning permission, and on the nearby Rookfield Estate an Article 4 direction covers all elevations of the houses. Where approval from Haringey Council is needed, our design team, working with your architect or ours, prepares and submits the application.

Common questions about building in Muswell Hill
Do I need planning permission for an extension in Muswell Hill?
A house (not a flat or maisonette) keeps 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 elsewhere. Haringey Council's Muswell Hill, Fortis Green, Rookfield and Alexandra Palace and Park conservation areas cover parts of N10. In them single-storey rear rights remain, but side extensions, two-storey rear extensions, cladding and roof additions need permission. The Muswell Hill Conservation Area has no Article 4 direction; the Rookfield Estate has one covering all elevations of the houses.
What does Haringey Council expect for loft conversions in Muswell Hill?
In the Muswell Hill Conservation Area, first designated in 1974, a dormer is not permitted development and needs a planning application. The Muswell Hill 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 be built as permitted development.
What does a dormer loft conversion cost in Muswell Hill?
Muswell Hill's Edwardian roofs have the height for a bedroom and en-suite. A rear dormer loft conversion typically costs £45,000–£75,000 and an L-shaped dormer £55,000–£85,000, both including VAT. Where the house sits in a conservation area, the planning application is part of the programme. Our dormer loft conversion cost guide shows what is included at each level.
