Planning in Barnet

Do I need planning permission in Hendon?

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 planning permission 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 loft conversion drawings in Hendon if the project runs on to construction.

From validation to decision

How long does Barnet Council take to decide?

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, house extension drawings follows for the NW4 property.

What we measure

What Hendon's housing stock means for your plans

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, on these 1930s semis the prior approval route often replaces a full application, and the drawing set is smaller as a result. 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 architectural drawings for NW4 properties and building regulations drawings, so the cost lands once.

Streets and landmarks we survey around Hendon

  • Golders Green — gardens deep enough for the 8 weeks householder route on a Golders Green plot.
  • Childs Hill — frontages visible from the highway, so Hampstead Garden Suburb materials detail governs the Childs Hill elevation.
  • North Circular Road — frontages visible from the highway, so Hampstead Garden Suburb materials detail governs the North Circular Road elevation.
  • Edgware Road — gardens deep enough for the 8 weeks householder route on a Edgware Road plot.
  • Watling Street — gardens deep enough for the 8 weeks householder route on a Watling Street plot.
  • Canons Park — shared flank walls, so Canons Park party structure notices go out before work starts.
  • Mill Hill — front-to-back level changes that drive the Mill Hill section drawings.
  • Sunny Hill Park — frontages visible from the highway, so Hampstead Garden Suburb materials detail governs the Sunny Hill Park elevation.
  • RAF Museum — schemes in view of it attract closer officer scrutiny.
  • Finchley Memorial Hospital — nearby 1930s semi-detached takes its scale from this frontage.
  • Hendon Library — a Hendon roof extension is judged against the datum it sets.
  • Brent Reservoir — proposals within its setting are drawn with the context elevation included.
  • Hasmonean High School — it fixes the local datum a Hendon roof extension is judged against.

Hendon questions

Planning Permission in Hendon — common questions

Is planning permission needed for a NW4 property in Hendon?

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.

How do conservation areas affect planning permission in Hendon?

For Hendon the answer is usually Hampstead Garden Suburb. Within its boundary permitted development shrinks and the RAF Museum streetscape carries weight.

What sort of Hendon homes do you work on?

Anything in Hendon — though most of it is 1930s semi-detached, post-war flats in NW4.

Do you take work beyond 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.
