This page covers the western part of the borough — Barnsbury, Holloway, Caledonian Road and Lower Holloway and the streets around them. The stock here is largely Georgian squares in Barnsbury and long runs of Victorian terraces, and we prepare drawings across every one of those types for Islington Council.
The Barnsbury conservation area protects the western Georgian squares, so side-return and rear extensions there are designed to match the period and submitted for full planning. Whichever route your address falls under, we confirm it free at the measured survey and design to match the western Islington streetscape — from period rear and side-return extensions to rear-dormer and mansard loft conversions.


Every application in West Islington is decided by Islington Council. Householder applications carry a statutory 8-week determination; allow around 12–14 weeks from first call to decision once the measured survey, design and validation are included. We hold a 98% first-time approval rate across Islington.
Article 4 Direction: 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.

Every Islington postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Islington fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| EC1V | City Road / Old Street | Georgian and early Victorian terraces | A drawing package at an EC1V address in City Road / Old Street is determined by Islington Council under its own Local Plan policies for City Road / Old Street. |
| EC1Y | Bunhill / Whitecross | Georgian and early Victorian terraces | EC1Y covers Bunhill / Whitecross only; Islington Council handles the drawing package, and Bunhill / Whitecross case officers apply the EC1Y conservation-area map. |
| 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. |
| N16 | Stoke Newington / Stamford Hill | Georgian and Victorian terraces | N16 straddles a boundary: Stoke Newington / Stamford Hill addresses fall to Hackney Council or Islington Council, so confirm which authority validates the drawing package before submitting N16 drawings. |
| WC1X | Bloomsbury / Mount Pleasant | Georgian and early Victorian terraces | WC1X straddles a boundary: Bloomsbury / Mount Pleasant addresses fall to Camden Council or Islington Council, so confirm which authority validates the drawing package before submitting WC1X drawings. |
| N1 | Islington / Hoxton | Georgian and early Victorian terraces | A drawing package in Islington / Hoxton may land with Islington Council or Hackney Council — N1 crosses the boundary, and the N1 policies map decides it street by street. |
| N5 | Highbury | Victorian terraces, mansion blocks | N5 covers Highbury only; Islington Council handles the drawing package, and Highbury case officers apply the N5 conservation-area map. |
| N7 | Holloway / Tufnell Park | Victorian villas and terraces | N7 covers Holloway / Tufnell Park only; Islington Council handles the drawing package, and Holloway / Tufnell Park case officers apply the N7 conservation-area map. |
Roof pitch, wall build-up and plot depth change every few Islington streets, and each one changes what a drawing package can achieve at that address.
Islington conservation designations: there are 40 across Islington Council, Angel, Barnsbury, Canonbury among them. Designation costs a Islington 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. Highbury is the Islington designation that most often changes a drawing package design.
Islington 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 N1 address is checked against that direction first; Islington Council publishes the Islington extent, and the N1 line rarely follows the Islington boundary you would expect.
What Islington is built from: Georgian and early Victorian terraces, Victorian bye-law housing, 1930s mansion blocks, converted industrial buildings in Clerkenwell and Farringdon. Densely terraced, gentrified; strong conservation area coverage; active planning department. That mix decides the drawing package route in Islington more than the postcode does, and it is what a Islington Council case officer reads first. A householder application costs £548 paid to Islington Council direct, with 8 weeks to a decision once validated.

Direct answers to what homeowners in western Islington ask about drawings, permission and fees.
It depends on your exact address. Many single-storey rear and side-return extensions on unlisted houses in West Islington fall under Permitted Development, but The Barnsbury conservation area protects the western Georgian squares, so side-return and rear extensions there are designed to match the period and submitted for full planning. Flats, listed buildings and conservation areas always need full planning, decided by Islington Council. Article 4 in the borough: Yes — check your address. We confirm exactly which route applies to your property, free, at the survey.
