Every Haringey postcode district we draw in, the stock that dominates it and the authority that validates a garage conversion there. Haringey fees below are the statutory England rates for 2026, not garage conversion estimates.
| Postcode | Area | Dominant stock | What it means for a garage conversion |
|---|---|---|---|
| N4 | Finsbury Park / Stroud Green | Victorian terraces, post-war estates | N4 straddles a boundary: Finsbury Park / Stroud Green addresses fall to Haringey Council or Islington Council or Hackney Council, so confirm which authority validates the garage conversion before submitting N4 drawings. |
| N8 | Crouch End / Hornsey | Edwardian terraces, Victorian villas | A garage conversion at an N8 address in Crouch End / Hornsey is determined by Haringey Council under its own Local Plan policies for Crouch End / Hornsey. |
| N10 | Muswell Hill | Edwardian villas, 1930s semi-detached | A garage conversion in Muswell Hill may land with Haringey Council or Barnet Council — N10 crosses the boundary, and the N10 policies map decides it street by street. |
| N15 | Seven Sisters / South Tottenham | Victorian terraces, post-war estates | N15 covers Seven Sisters / South Tottenham only; Haringey Council handles the garage conversion, and Seven Sisters / South Tottenham case officers apply the N15 conservation-area map. |
| N17 | Tottenham | Victorian terraces, post-war estates | A garage conversion at an N17 address in Tottenham is determined by Haringey Council under its own Local Plan policies for Tottenham. |
| N22 | Wood Green / Alexandra Palace | Edwardian terraces, post-war flats | N22 covers Wood Green / Alexandra Palace only; Haringey Council handles the garage conversion, and Wood Green / Alexandra Palace case officers apply the N22 conservation-area map. |
| N6 | Highgate | Georgian villas, Victorian and Edwardian semis | Highgate is split at N6. Either Camden Council or Haringey Council can determine a garage conversion here, so the N6 address is checked against both policies maps first. |
Roof pitch, wall build-up and plot depth change every few Haringey streets, and each one changes what a garage conversion can achieve at that address.
Conservation areas covering Haringey: Haringey Council runs 29, and Tottenham Green, Bruce Castle, Highgate Village are the ones Haringey owners meet most. A garage conversion inside a Haringey conservation area loses permitted development, so the Haringey submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Crouch End a garage conversion is judged on the street elevation first.
Article 4 and your Haringey garage conversion: Borough-wide Article 4 for HMO conversions. At a N4 address that matters twice over, because Haringey Council applies the direction unevenly across Haringey — we read the Haringey policies map for the exact N4 address before quoting garage conversions.
Haringey housing stock: Edwardian terraces in Crouch End, Muswell Hill; Victorian two-up-two-downs in Harringay Ladder; 1930s semi-detached in Muswell Hill; post-war in Tottenham. Muswell Hill and Crouch End have strong conservation coverage with clear loft/mansard precedents; Tottenham generally permissive. Read that before choosing a garage conversion route in Haringey — construction, not postcode, sets what is achievable. Haringey Council charges £548 for a householder application and has 8 weeks to determine it.

Of 124 change-of-use appeals decided in Haringey over the window covering appeals decided 2016-2026, Haringey was upheld more often than most London councils — only 23.4% of appeals succeeded, against 29.1% across London. 29 were allowed and 95 dismissed. Turning a garage or outbuilding into habitable space is usually decided as a change of use, and 124 such Haringey decisions were challenged far enough to reach an inspector.
Half of those Haringey appeals took more than 116 days to decide from the day the appeal started — time added on top of the council's own determination period, which is the argument for getting the application right first. 97.6% were decided by written representations rather than a hearing or inquiry, meaning the written case and the drawings were the whole of the evidence.

Direct answers to the questions Haringey homeowners ask every week about garage conversion drawings.
Start a free quote →Most integral garage conversions in Haringey do not require planning permission — they're classed as an internal alteration, which is not development under the TCPA 1990. However, if the conversion materially alters the external appearance (new windows, raising the roof), planning permission may be required. Detached garage conversions to habitable use always need planning. Article 4 Directions in Haringey may also affect eligibility. We confirm the planning route before quoting.
A Haringey garage conversion is one of the cheapest ways to add habitable space: our package covers the planning route assessment, building regulations drawings and structural calculations for the door opening.

Typically yes — a well-executed garage conversion in Haringey adds 10–15% to property value and costs far less per square metre than an extension. In areas where parking is not at a premium, converting an underused garage is one of the most cost-effective ways to gain living space.
A standard integral garage conversion in Haringey typically takes 4–6 weeks to build once drawings are approved. Our architectural package takes 3–4 weeks from instruction to Building Control submission. Total timeline: approximately 3–4 months from initial survey to completion.
