Planning Drawings · N7 Holloway

The borough-level guide to planning drawings in Islington sets out how the same work is handled across the rest of the authority.
Planning drawings for Holloway start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Islington Council. On N7's victorian terraces, many converted to flats, with, the recurring questions are roof additions, rear and side-return extensions, and alterations within Hillmarton, Tufnell Park, Camden Road. We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for Holloway, Tufnell Park, Lower Holloway, Hillmarton.
Across Holloway, Tufnell Park, Lower Holloway, Hillmarton in N7, the dominant property is victorian terraces, many converted to flats, with post-war estates and pockets of larger housing around holloway and tufnell park. That stock shapes what planning permission drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Islington Council judges each on design quality and neighbour impact. We survey the specific Holloway property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the N7 streetscape.

Yes. The Victorian terraces around Hillmarton and Mackenzie Road suit side-return and rear extensions and loft conversions, much of it within Permitted Development outside the conservation areas, confirmed with a Lawful Development Certificate. Inside Hillmarton or Tufnell Park, full planning applies. We confirm and draw to Islington's checklist.
The former Holloway Prison site is being redeveloped into new homes and public space, improving the area around Parkhurst Road and supporting values. For a house project the binding controls remain Permitted Development limits and the local conservation area, which we check for your address.
Yes. Much of Holloway is converted flats in Victorian terraces, where alterations touch shared structure and party walls, so we produce drawings that satisfy the freeholder and Islington Building Control, and serve Party Wall notices where works affect neighbours.
Usually yes outside the conservation areas — an L-shaped rear dormer within the volume allowance, confirmed by a Lawful Development Certificate. Inside Hillmarton, Tufnell Park or Camden Road, roof changes need full planning. We confirm which applies to your road.

Almost always. Any structural work behind planning permission drawings in Holloway — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Islington Council Building Control or an approved inspector. On N7's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. With Holloway (N7) property at around £500,000 for a flat and £1m-£1.4m for a house, a well-designed extension or loft typically returns more than it costs in added floor area and sale value. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on N7 homes.
Extensions on a boundary plot can involve two authorities. Everything we draw and submit is listed for N1, N4, N5, N16 and N19.

Article 4 and your N7 (Holloway / Tufnell Park) planning drawing set: Article 4 Direction covering the whole borough removes permitted development rights for HMO conversions (C3 to C4).
