Planning drawings for Barnet start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Barnet Council. On EN5's victorian and edwardian houses and inter-war semis, the recurring questions are roof additions, rear and side-return extensions, and alterations within Monken Hadley, Wood Street, Hadley Green. We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for High Barnet, Monken Hadley, Arkley, Hadley Green.
A fixed-fee, end-to-end service — measured survey, scaled drawings, Design & Access Statement where required, Planning Portal submission, and full agent liaison until the council's decision.
Across High Barnet, Monken Hadley, Arkley, Hadley Green in EN5, the dominant property is victorian and edwardian houses and inter-war semis around barnet, with the historic monken hadley and wood street conservation core. 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 Barnet Council judges each on design quality and neighbour impact. We survey the specific Barnet property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the EN5 streetscape.

Planning + building regs + structural.
Listed, conservation or complex sites.
Yes. The Victorian and Edwardian houses and inter-war semis suit rear, side and loft extensions. The historic Monken Hadley, Wood Street and Hadley Green conservation areas mean changes there need full planning with a Heritage Statement; outside them, much runs on the Permitted Development route, confirmed with a Lawful Development Certificate. We confirm which applies.
Very — the Monken Hadley conservation area protects one of north London's most intact historic villages, around Hadley Green and the common, so external changes are carefully assessed on materials, height and setting. We produce a sympathetic design and Heritage Statement and handle the Barnet application.
Toward Arkley and the northern fringe, properties may sit in or near the metropolitan green belt, which tightly limits extending the footprint. We check whether your plot is washed over by green belt before designing; in the built-up area, normal householder rules apply.
From inter-war semis around £600,000 to Monken Hadley houses above £1.3m, a consented extension or loft adds significant value and family space. The conservation core raises the bar, so professional drawings and heritage justification matter — our fixed fee keeps the cost predictable.
Our fixed fee for planning permission drawings in Barnet starts at £840 — no hourly billing. With Barnet property at around £350,000 for a flat and £600,000-£1.3m for a house, the professional drawing fee is a small fraction of the value the work adds to EN5's victorian and edwardian houses and inter-war semis. Barnet Council charges its own statutory application fee on top (currently £258 for a householder planning application, £578 for a full application). We quote the drawings as one fixed price and the free site survey covers every EN5 address.
For a EN5 project across High Barnet, Monken Hadley, Arkley, Hadley Green, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Barnet Council (8 weeks for a householder application). We carry the Barnet application through every officer query to the decision.
Barnet (EN5) sits primarily in Barnet, so applications are decided by Barnet Council. Article 4 in force in the borough: No. Conservation areas within EN5 include Monken Hadley, Wood Street, Hadley Green, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind planning permission drawings in Barnet — 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 Barnet Council Building Control or an approved inspector. On EN5'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 Barnet (EN5) property at around £350,000 for a flat and £600,000-£1.3m for a house, a well-designed extension or loft typically returns more than it costs in added floor area and sale value, while our fixed drawing fee from £840 keeps the professional cost predictable. 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 EN5 homes.

Every EN5 postcode district we draw in, the stock that dominates it and the authority that validates a planning drawing set there. EN5 fees below are the statutory England rates for 2026, not planning drawing set estimates.
| Postcode | Area | Dominant stock | What it means for a planning drawing set |
|---|---|---|---|
| EN5 | Barnet / Arkley | Georgian fragments, 1930s semi-detached | Barnet / Arkley sits wholly inside EN5, so Barnet Council validates every planning drawing set submitted from an EN5 address. |
| EN5 | Barnet | Georgian fragments, 1930s semi-detached | Barnet sits inside EN5; planning drawing set proposals here are determined by Barnet Council. |

| N3 | Finchley Central | 1930s semi-detached, Edwardian villas | Adjoining district to EN5, also inside Barnet for planning drawing set purposes. |

EN5 (Barnet / Arkley) conservation designations: there are 20 across Barnet Council, Monken Hadley, Hampstead Garden Suburb, Mill Hill among them. Designation costs a EN5 (Barnet / Arkley) owner the permitted-development route: a planning drawing set then needs a £258 householder application over 8 weeks, in place of the £120 prior approval route that takes 6 weeks. Mill Hill is the EN5 (Barnet / Arkley) designation that most often changes a planning drawing set design.
No blanket Article 4 over EN5 (Barnet / Arkley): Barnet Council has not withdrawn permitted development across EN5 (Barnet / Arkley), so a planning drawing set outside a EN5 (Barnet / Arkley) conservation area usually keeps it. The £129 Lawful Development Certificate is still the document a EN5 owner wants on file.
