Every Barnet postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Barnet fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| NW4 | Hendon | 1930s semi-detached, post-war flats | NW4 covers Hendon only; Barnet Council handles the drawing package, and Hendon case officers apply the NW4 conservation-area map. |
| NW7 | Mill Hill | Georgian villas, 1930s detached and semi-detached | A drawing package at an NW7 address in Mill Hill is determined by Barnet Council under its own Local Plan policies for Mill Hill. |
| NW9 | Colindale / Kingsbury | Post-war flats, new-build | Colindale / Kingsbury is split at NW9. Either Barnet Council or Brent Council can determine a drawing package here, so the NW9 address is checked against both policies maps first. |
| NW11 | Golders Green / Hampstead Garden Suburb | Arts & Crafts houses, Edwardian villas | A drawing package at an NW11 address in Golders Green / Hampstead Garden Suburb is determined by Barnet Council under its own Local Plan policies for Golders Green / Hampstead Garden Suburb. |
| EN4 | East Barnet / Cockfosters | 1930s semi-detached dominates; Edwardian villas in Muswell Hill | EN4 straddles a boundary: East Barnet / Cockfosters addresses fall to Barnet Council or Enfield Council, so confirm which authority validates the drawing package before submitting EN4 drawings. |
| EN5 | Barnet / Arkley | Georgian fragments, 1930s semi-detached | EN5 covers Barnet / Arkley only; Barnet Council handles the drawing package, and Barnet / Arkley case officers apply the EN5 conservation-area map. |
| HA8 | Edgware / Burnt Oak | 1930s semi-detached, post-war flats | Edgware / Burnt Oak sits wholly inside HA8, so Barnet Council validates every drawing package submitted from an HA8 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. |
Roof pitch, wall build-up and plot depth change every few Barnet streets, and each one changes what a drawing package can achieve at that address.
Barnet conservation designations: there are 20 across Barnet Council, Hampstead Garden Suburb, Mill Hill, Hendon among them. Designation costs a Barnet owner the permitted-development route: a drawing package then needs a £258 householder application over 8 weeks, in place of the £120 prior approval route that takes 6 weeks. Hampstead Garden Suburb is the Barnet designation that most often changes a drawing package design.
Article 4 and your Barnet drawing package: Barnet Council has made no borough-wide direction, so permitted development for a drawing package in Barnet generally survives outside Barnet conservation areas and listed curtilages. A Lawful Development Certificate at £129 is how a N2 owner records that a drawing package was lawful.
