EC1V primarily covers City Road / Old Street in Islington.
Decisions for EC1V 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.
Building regs from £950. We do not charge hourly. Free site survey across all EC1V 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. Islington Council timelines align with the national norm.
City Road / Old Street in EC1V is characterised by the housing stock of Islington — broadly georgian and early victorian terraces.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every EC1V postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. EC1V 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. |
| EC1V | Angel | Georgian and early Victorian terraces | Angel sits inside EC1V; drawing package proposals here are determined by Islington Council. |
| N1 | Islington / Hoxton | Georgian and early Victorian terraces | Adjoining district to EC1V, also inside Islington for drawing package purposes. |

Roof pitch, wall build-up and plot depth change every few EC1V streets, and each one changes what a drawing package can achieve at that address.
EC1V (City Road / Old Street) conservation designations: there are 40 across Islington Council, Angel, Barnsbury, Canonbury among them.

Highbury is the EC1V (City Road / Old Street) designation that most often changes a drawing package design.
Article 4 and your EC1V (City Road / Old Street) drawing package: 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. At a EC1V address that matters twice over, because Islington Council applies the direction unevenly across EC1V (City Road / Old Street) — we read the EC1V (City Road / Old Street) policies map for the exact EC1V address before quoting architectural drawings.
The building fabric around EC1V (City Road / Old Street): 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. A drawing package in EC1V (City Road / Old Street) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Islington Council.
