Harlesden (NW10) is a dense Victorian terraced neighbourhood built around the High Street and the landmark Jubilee Clock, with a high share of houses already converted to flats. That mix means the work here spans rear and side-return extensions, loft conversions and the drawings that go with flat-conversion and change-of-use schemes.

The Harlesden conservation area covers the historic core around the High Street, so frontage changes, dormers and materials there face tighter control than on the surrounding streets. We check where a Harlesden property sits relative to that boundary, and whether it is in single-family or flatted use, before recommending a route and preparing the application to Brent's standards.

Planning in Harlesden (NW10): what to know before you apply

NW10 has no published householder Article 4 direction in Harlesden affecting typical extensions, so many terraces retain permitted development rights — but the Harlesden conservation area around the High Street is the exception, and the high level of existing flat conversions means amenity and layout are scrutinised closely.

Typical Harlesden housing stock

Dense Victorian terraces radiating from the High Street and the Jubilee Clock, a large share already converted to flats, alongside pockets of later infill — a mix that makes both extensions and conversion-related work common.

Planning Drawings for Harlesden (NW10) homes: the package and the process

Every planning drawings we prepare for an Harlesden property is drawn to London Borough of Brent’s validation standards and tuned to the NW10 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Planning drawings are the scale drawings a London council uses to judge your application: existing and proposed floor plans, elevations, sections and site plans that show the design, scale and neighbour impact of your project. DrawingsDirect produces complete, validation-ready planning drawing sets for extensions, lofts and conversions across London.

What is included in a planning drawing set?

A council will only validate an application that contains the right drawings at the right scale. Our standard planning set covers everything a London validation team expects.

  • Site location plan (1:1250) and block plan (1:500)
  • Existing floor plans, elevations and sections
  • Proposed floor plans, elevations and sections
  • Roof plans where relevant, with heights and materials annotated
  • A design and access or heritage statement where the borough requires one

How are planning drawings different from building regulations drawings?

Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.

FAQ

Planning Drawings in Harlesden NW10 — FAQs

What scale should London planning drawings be?+
Site location plans are 1:1250, block plans 1:500, and floor plans, elevations and sections are typically 1:100 or 1:50. We format every drawing to your specific borough's requirements.
Do I need an architect to produce planning drawings?+
No. MCIAT-chartered architectural technologists produce the same council-accepted planning drawings with the same professional accountability, and councils assess the drawings, not the author's job title.
How many revisions are included in the fee?+
All of them. The fee is fixed and we redraw free until your council approves — revisions requested by a planning officer never cost you extra.
Can you draw from my existing plans?+
We can work from existing measured drawings, but for accuracy we usually carry out a laser survey so the proposed set matches your property exactly.
Do planning drawings guarantee approval?+
No drawing can guarantee a decision, but drawing to the local plan and validation checklist maximises your odds — and we redraw free until approval.
Do I need planning permission for a side-return extension in Brent?+
On the Victorian and Edwardian terraces of Kilburn, Willesden and Harlesden a single-storey side-return or rear extension can fall within permitted development, so a full application isn't always needed. Conservation areas such as Queen's Park and Mapesbury restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate where it qualifies.
What does Brent's borough-wide HMO Article 4 direction affect?+
Brent applies a borough-wide Article 4 direction removing permitted development rights for change of use to an HMO (C3 to C4), so a conversion to a house in multiple occupation needs a full application anywhere in the borough. It doesn't affect a standard family extension or loft, but we confirm whether it applies to your intended use before advising.
Is a hip-to-gable loft conversion allowed on my Brent semi?+
Frequently, yes. The interwar semis of Wembley, Kingsbury and Sudbury suit hip-to-gable and dormer conversions, which often qualify as permitted development within the volume limits. We confirm eligibility against those limits and any conservation or Article 4 constraint, then produce the planning and building-regulations drawings.
How long does Brent Council take to decide?+
Brent determines most householder applications within the statutory eight-week period once validated; conservation cases can attract additional consultation. The dense terraced streets are party-wall-sensitive, so the commonest delay is a drawing query — we prepare submissions to the council's householder guidance to keep them moving.
How much do planning drawings cost in Brent?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Brent approves. A side-return, a hip-to-gable loft and a conservation-area application differ in complexity, so we quote once we understand your street and project rather than by the hour.
