Questions about N7

N7 planning FAQ

What borough is N7?

N7 primarily covers Holloway / Tufnell Park in Islington.

Do I need planning permission in N7?

Decisions for N7 are made by Islington 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 Islington: Yes.

What does it cost to get drawings in N7?

Building regulations packages start at £950, quoted as a fixed figure rather than billed by the hour, and the site survey is free at every N7 address, whether it sits down in Holloway or up towards Tufnell Park.

How long does a project take in N7?

Reckon on 12 to 14 weeks from the first call to a decision: survey in week 1, design through weeks 2 and 3, then 1 to 2 weeks of validation before the statutory 8 weeks even begins. One local caveat is worth having. Of the 1,279 householder decisions Islington issued, 665 were taken under a performance agreement or an extension of time (MHCLG PS1/PS2, retrieved 1 September 2026), so the eight-week clock is paused here far more often than the headline target implies.

What housing stock dominates N7?

Holloway and Tufnell Park are built out of Islington's characteristic Georgian and early Victorian terraces, and 35.9% of the borough's 112,160 homes predate 1900 (VOA CTSOP4.1, 31 March 2025). On stock that old, whether permitted development still applies is a question rather than an assumption, which is why the certificate route gets so much use: the borough recorded 398 certificates of lawful development, counted from the April 2023 quarter through to the March 2026 one (MHCLG PS1/PS2, retrieved 1 September 2026). No English district publishes a success rate for certificates, so that number tells you how often the route is taken and nothing about how often it succeeds.

Where in N7 does a drawing package actually get determined?

N7 taken area by area: where we draw, what stands there, and who validates a drawing package sent in from the address. Listed charges are 2026 statutory England fees, set nationally.

How does a drawing package differ street by street across N7?

Between one N7 terrace and the next, pitch, wall build-up and rear plot depth all move, and each of them widens or narrows what a drawing package can propose.

How do conservation areas and Article 4 affect a drawing package in N7?

How designation changes a N7 (Holloway / Tufnell Park) drawing package: Islington Council maintains 40 conservation areas, including Barnsbury, Canonbury, Highbury. Inside any of them a N7 (Holloway / Tufnell Park) drawing package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Barnsbury sets the tone for N7 (Holloway / Tufnell Park) casework.

N7 (Holloway / Tufnell Park) and Article 4: Article 4 Direction covering the whole borough removes permitted development rights for HMO conversions (C3 to C4). Separate Article 4 for office-to-residential in key areas. A drawing package planned at a N7 address is checked against that direction first; Islington Council publishes the N7 (Holloway / Tufnell Park) extent, and the N7 line rarely follows the N7 (Holloway / Tufnell Park) boundary you would expect.

What N7 is built from: Georgian and early Victorian terraces, Victorian bye-law streets, 1930s mansion blocks, and industrial buildings converted towards Clerkenwell and Farringdon. Dense, gentrified, heavily covered by conservation designation, and worked by an active planning department. That mixture rather than the postcode itself decides which route a drawing package takes, and it is the first thing an Islington case officer reads. A householder application costs £548 paid direct to the council, with 8 weeks to a decision once validated. Around 3% of N7 sales fall over the boundary into Camden, so we check the address before anyone pays a fee.

What happens if a N7 property sits on a boundary?
