A measured building survey captures your Barnet property exactly — every wall, opening, level and boundary — as the accurate base for design and planning drawings. On EN5's older terraced and villa stock around High Barnet, Monken Hadley, Arkley, Hadley Green, walls are rarely square, so a laser-measured survey prevents costly errors before Barnet Council ever sees the application.
Fixed-fee measured surveys across Barnet from £540 — floor plans, elevations and sections to ±3mm accuracy. Leica Disto laser + BLK360 point-cloud scanning, AutoCAD and Revit deliverables, MCIAT chartered.
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 measured building survey 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.
Housing stock in EN5: Victorian and Edwardian houses and inter-war semis around Barnet, with the historic Monken Hadley and Wood Street conservation core.
Within the district: High Barnet, Monken Hadley, Arkley, Hadley Green.
Streets we know in EN5: the Wood Street and Hadley Green roads, the Monken Hadley village streets and the larger plots toward Arkley. Each road has its own building line, boundary treatment and precedent that Barnet Council weighs when assessing a measured building survey scheme.
Conservation areas: Monken Hadley, Wood Street, Hadley Green. Inside these, most external work needs full planning and a Heritage Statement.
Getting around EN5: High Barnet (Northern line terminus) and New Barnet on Thameslink serve EN5.
Regeneration: Barnet falls within or beside the Barnet town centre (Spires), which shapes local planning policy and design expectations.
Property values: around £350,000 for a flat and £600,000-£1.3m for a house — a useful gauge of the build value an extension or loft adds in EN5.
Borough character: Suburban outer-London borough; permitted development used heavily; Hampstead Garden Suburb has its own residents' trust with additional design controls.

Single planning or building-regs submission.
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 measured building survey in Barnet starts at £540 — 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 measured building survey 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 £540 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.

| Postcode | Area | Dominant stock | What it means for a measured building survey |

How designation changes a EN5 (Barnet / Arkley) measured building survey: Barnet Council maintains 20 conservation areas, including Golders Green, Monken Hadley, Hampstead Garden Suburb. Inside any of them a EN5 (Barnet / Arkley) measured building survey cannot rely on permitted development, and the route becomes a £258 householder application determined in 8 weeks rather than a £120 prior approval in 6 weeks. Hendon sets the tone for EN5 (Barnet / Arkley) casework.
Article 4 and your EN5 (Barnet / Arkley) measured building survey: Barnet Council has made no borough-wide direction, so permitted development for a measured building survey in EN5 (Barnet / Arkley) generally survives outside EN5 (Barnet / Arkley) conservation areas and listed curtilages. A Lawful Development Certificate at £129 is how a EN5 owner records that a measured building survey was lawful.
