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.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| N4 | Finsbury Park / Stroud Green | Victorian terraces, post-war estates | Finsbury 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. |
| N8 | Crouch End / Hornsey | Edwardian terraces, Victorian villas | Crouch End / Hornsey sits wholly inside N8, so Haringey Council validates every drawing package submitted from an N8 address. |
| N10 | Muswell Hill | Edwardian villas, 1930s semi-detached | Muswell 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. |
| N15 | Seven Sisters / South Tottenham | Victorian terraces, post-war estates | N15 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. |
| N17 | Tottenham | Victorian terraces, post-war estates | A drawing package 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 | A 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. |
| N6 | Highgate | Georgian villas, Victorian and Edwardian semis | Highgate 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. |
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.
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.

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.
| Measure | Haringey | Context |
|---|---|---|
| Householder applications decided | 2,227 | 77,680 across London |
| Householder approval rate | 89.5% | 83% London average |
| Decided within 8 weeks | 88.0% | 27th fastest of 32 boroughs |
| Took longer than 13 weeks | 7.3% | the applications that overran the statutory target |
| Minor dwellings approval rate | 81.0% | new-build and conversion schemes under 10 units |
| All application types | 85.8% | across 4,430 decisions |
| Certificates of lawfulness issued | 1,023 | confirmations that work was permitted development |
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.
