N2 primarily covers East Finchley in Barnet.
Decisions for N2 are made by Barnet Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Barnet: No.
Building regs from £950. We do not charge hourly. Free site survey across all N2 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Barnet Council timelines align with the national norm.
East Finchley in N2 is characterised by the housing stock of Barnet — broadly 1930s semi-detached dominates.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every N2 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. N2 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| N2 | East Finchley | Edwardian terraces, 1930s semi-detached | East Finchley sits wholly inside N2, so Barnet Council validates every drawing package submitted from an N2 address. |
| N3 | Finchley Central | 1930s semi-detached, Edwardian villas | Adjoining district to N2, also inside Barnet for drawing package purposes. |
| N11 | New Southgate / Bounds Green | mixed stock | Adjoining district to N2, also inside Barnet for drawing package purposes. |
| N12 | North Finchley / Woodside Park | 1930s semi-detached, Edwardian villas | Adjoining district to N2, also inside Barnet for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few N2 streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering N2 (East Finchley): Barnet Council runs 20, and Mill Hill, Hendon, Golders Green are the ones N2 (East Finchley) owners meet most. A drawing package inside a N2 (East Finchley) conservation area loses permitted development, so the N2 (East Finchley) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Hendon a drawing package is judged on the street elevation first.
Article 4 and your N2 (East Finchley) drawing package: Barnet Council has made no borough-wide direction, so permitted development for a drawing package in N2 (East Finchley) generally survives outside N2 (East Finchley) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a N2 owner records that a drawing package was lawful.
N2 (East Finchley) housing stock: 1930s semi-detached dominates; Edwardian villas in Muswell Hill, Finchley; Garden Suburb Arts & Crafts in Hampstead Garden Suburb; post-war flats in Colindale. Suburban outer-London borough; permitted development used heavily; Hampstead Garden Suburb has its own residents' trust with additional design controls. Read that before choosing a drawing package route in N2 (East Finchley) — construction, not postcode, sets what is achievable. Barnet Council charges £548 for a householder application and has 8 weeks to determine it.
