Chartered measured floor plans and elevations for the NW4 area. No hourly billing, and around 30% below typical London architect rates. Work at a Hendon address is decided by Barnet Council, the local planning authority for Barnet, under Barnet Local Plan policy.
Architectural Drawings in Hendon — scaled Hendon floor plans, elevations and sections describing a NW4 property as existing and as proposed — are submitted to Barnet Council for any NW4 address. They are weighed against the Barnet Local Plan, and they start with a laser measured survey of the Hendon address and carry every NW4 submission to Barnet Council, householder application through to full plans.
No Article 4 Direction covers Barnet, which keeps the Hendon permitted-development route open on unlisted houses. Hendon is 1930s semi-detached, post-war flats — a architectural drawings submission has to answer that context rather than a generic London template. Hampstead Garden Suburb is the designation that most often reshapes a Hendon proposal; Barnet carries 20 of them. The designation map is read street by street in Hendon.
That mapping of Article 4 directions across Hendon happens before design, which is what keeps the Barnet Council route predictable. On Hendon stock the constraint is physical before it is planning: the 1930s semi-detached fixes the rear wall line and the RAF Museum roofline caps the ridge. The borough policy layer over every NW4 address is set out on Barnet planning. The Hendon survey then carries into building regulations drawings in Hendon if the project runs on to construction.



Barnet Council will not register a Hendon application until validation completes. No Hendon design work starts until the measured survey is complete.
Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.
Expect a site visit to the Hendon property during the consultation period. We format the Hendon set exactly as Barnet Council wants to receive it.
London Borough of Barnet weighs material objections only — a Hendon neighbour disliking the design is not one. Party wall positions on a Hendon terrace are located during the survey.
Budget notice time on any Hendon job touching a shared wall. Once consent is granted, loft conversion drawings follows for the NW4 property.
Hendon is characterised by 1930s semi-detached, post-war flats, concentrated across NW4 in the Hendon area. The 1930s semi-detached across Hendon decides how a scheme is built, not just how it looks. On NW4 plots specifically, 1930s semis here are dimensionally consistent, so the survey is quick and the drawings come back inside the shorter end of the window. On a Hendon terrace it governs the rear opening width. Because the Hendon streetscape near RAF Museum is consistent, departures in ridge height read immediately in an officer report.
Barnet sets no special basement rule, so a Hendon lower-ground scheme stands or falls on the engineering and the neighbours. The Hendon measured survey is reused across house extension drawings for NW4 properties and planning permission, so the cost lands once.
Each Hendon instruction produces this set of drawings.
Surveyors travel to NW4 addresses from the studio; the nearest stations are Hendon, Hendon Central, Welsh Harp. Appointments are booked in Hendon on weekdays and Saturdays, and the measured survey of a standard 1930s semi-detached takes two to three hours.
Hendon lies 7 miles (11 km) northwest of Charing Cross, on Ordnance Survey grid reference TQ229887. Those coordinates matter in practice: a site location plan for Barnet Council must be drawn to a recognised scale over the correct grid square. Source.

Drawings for Hendon are issued under MCIAT charter, which is the technical design and construction-detailing qualification rather than an RIBA registration. A tight Hendon plot — RAF Museum in the setting, a shared flank wall on NW4 — goes to Barnet Council for advice before it goes to determination.
Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations.

Depends on the NW4 property. Flats always need consent; unlisted Hendon houses outside Hampstead Garden Suburb often do not. No Article 4 Direction covers Barnet, which keeps the Hendon permitted-development route open on unlisted houses.
For Hendon the answer is usually Hampstead Garden Suburb. Within its boundary permitted development shrinks and the RAF Museum streetscape carries weight.
Anything in Hendon — though most of it is 1930s semi-detached, post-war flats in NW4.
We cover Bush Hill Park, the wider Barnet area and across into Brent. The reason Hendon has a separate page is that a consent granted a mile off is no precedent for a NW4 street.
