Where in Haringey does a drawing package actually get determined?

Every Haringey postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Haringey fees below are the statutory England rates for 2026, not drawing package estimates.

PostcodeAreaDominant stockWhat it means for a drawing package
N4Finsbury Park / Stroud GreenVictorian terraces, post-war estatesFinsbury Park / Stroud Green is split at N4. Either Haringey Council or Islington Council or Hackney Council can determine a drawing package here, so the N4 address is checked against both policies maps first.
N8Crouch End / HornseyEdwardian terraces, Victorian villasCrouch End / Hornsey sits wholly inside N8, so Haringey Council validates every drawing package submitted from an N8 address.
N10Muswell HillEdwardian villas, 1930s semi-detachedMuswell Hill is split at N10. Either Haringey Council or Barnet Council can determine a drawing package here, so the N10 address is checked against both policies maps first.
N15Seven Sisters / South TottenhamVictorian terraces, post-war estatesN15 covers Seven Sisters / South Tottenham only; Haringey Council handles the drawing package, and Seven Sisters / South Tottenham case officers apply the N15 conservation-area map.
N17TottenhamVictorian terraces, post-war estatesA drawing package at an N17 address in Tottenham is determined by Haringey Council under its own Local Plan policies for Tottenham.
N22Wood Green / Alexandra PalaceEdwardian terraces, post-war flatsA drawing package at an N22 address in Wood Green / Alexandra Palace is determined by Haringey Council under its own Local Plan policies for Wood Green / Alexandra Palace.
N6HighgateGeorgian villas, Victorian and Edwardian semisHighgate is split at N6. Either Camden Council or Haringey Council can determine a drawing package here, so the N6 address is checked against both policies maps first.

What changes about a drawing package in each part of Haringey?

Roof pitch, wall build-up and plot depth change every few Haringey streets, and each one changes what a drawing package can achieve at that address.

What local planning policy applies to a drawing package in Haringey?

Haringey conservation designations: there are 29 across Haringey Council, Bruce Castle, Highgate Village, Muswell Hill among them. Designation costs a Haringey owner the permitted-development route: a drawing package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Bruce Castle is the Haringey designation that most often changes a drawing package design.

Article 4 and your Haringey drawing package: 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 architectural drawings.

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 drawing package 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.

What are the chances of approval in Haringey?

Over the 12 quarters from 2023 Q2 to 2026 Q1, Haringey decided 2,227 householder planning applications and approved 89.5% of them — 6.5 percentage points above the London average of 83%. That places Haringey 7th of 32 London boroughs on householder approval rate. These are decisions the council reported to MHCLG, not our own sample.

Speed matters as much as the odds. Haringey decided 88.0% of householder applications inside the eight-week statutory period and let 7.3% run past thirteen weeks. A drawing package that is complete and correctly described at validation is the part of that timeline you control; the rest belongs to the council's caseload.
