Where in Islington does a 1930s semi project actually get determined?
Every Islington postcode district we draw in, the stock that dominates
it and the authority that validates a 1930s semi project there. Islington fees below are the
statutory England rates for 2026, not 1930s semi project estimates.
| Postcode | Area | Dominant stock | What it means for a 1930s semi project |
|---|
| N4 | Finsbury Park / Stroud Green | Victorian terraces, post-war estates | N4 straddles a boundary: Finsbury Park / Stroud Green addresses fall to Haringey Council or Islington Council or Hackney Council, so confirm which authority validates the 1930s semi project before submitting N4 drawings. |
| N16 | Stoke Newington / Stamford Hill | Georgian and Victorian terraces | A 1930s semi project in Stoke Newington / Stamford Hill may land with Hackney Council or Islington Council — N16 crosses the boundary, and the N16 policies map decides it street by street. |
| WC1X | Bloomsbury / Mount Pleasant | Georgian and early Victorian terraces | A 1930s semi project in Bloomsbury / Mount Pleasant may land with Camden Council or Islington Council — WC1X crosses the boundary, and the WC1X policies map decides it street by street. |
| N1 | Islington / Hoxton | Georgian and early Victorian terraces | Islington / Hoxton is split at N1. Either Islington Council or Hackney Council can determine a 1930s semi project here, so the N1 address is checked against both policies maps first. |
| N5 | Highbury | Victorian terraces, mansion blocks | Highbury sits wholly inside N5, so Islington Council validates every 1930s semi project submitted from an N5 address. |
| N7 | Holloway / Tufnell Park | Victorian villas and terraces | N7 covers Holloway / Tufnell Park only; Islington Council handles the 1930s semi project, and Holloway / Tufnell Park case officers apply the N7 conservation-area map. |
| N19 | Archway / Tufnell Park | Victorian terraces, post-war flats | A 1930s semi project in Archway / Tufnell Park may land with Islington Council or Camden Council — N19 crosses the boundary, and the N19 policies map decides it street by street. |
| EC1M | Clerkenwell | Georgian and early Victorian terraces | Clerkenwell sits wholly inside EC1M, so Islington Council validates every 1930s semi project submitted from an EC1M address. |

Does Islington planning policy restrict a 1930s semi project?
Islington conservation designations: there are 40 across Islington Council, Clerkenwell, Angel, Barnsbury among them. Designation costs a Islington owner the permitted-development route: a 1930s semi project then needs a £258 householder application over 8 weeks, in place of the £120 prior approval route that takes 6 weeks. Clerkenwell is the Islington designation that most often changes a 1930s semi project design.
Article 4 and your Islington 1930s semi project: 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 N1 address that matters twice over, because Islington Council applies the direction unevenly across Islington — we read the Islington policies map for the exact N1 address before quoting 1930s semi projects.
The building fabric around Islington: 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 1930s semi project in Islington is scoped against that stock first. Our Islington fixed fee starts at £840; the £1,750 Complete package runs the Islington scheme through Islington Council planning and building control in one go.
Who decides a 1930s semi project on the edge of Islington?
- Camden — the Camden boundary runs against Islington, so a 1930s semi project a street from Islington is decided by Camden Council instead. Camden runs 40 conservation areas across NW1 and its neighbours, which is why 1930s semi projects priced for Islington are re-checked against Camden policy whenever the Islington address sits on that edge.
- Hackney — adjoining Islington, with 29 conservation areas centred on E2. A 1930s semi project on the far side of the Islington line is determined by Hackney Council, so the Islington quote for 1930s semi projects is checked against Hackney guidance before it is issued.
- Haringey — adjoining Islington, with 29 conservation areas centred on N4. A 1930s semi project on the far side of the Islington line is determined by Haringey Council, so the Islington quote for 1930s semi projects is checked against Haringey guidance before it is issued.
- City of London — cross the Islington boundary and City of London Corporation takes the 1930s semi project instead, applying 27 conservation areas of its own around EC1. We re-price 1930s semi projects at the Islington edge because City of London policy and Islington policy rarely align on 1930s semi project depth.
