Planning Permission in Brent
Fixed-fee, MCIAT-chartered planning permission for Brent homeowners — London Borough of Brent validation and local constraints handled from the start.
Brent runs from the dense Victorian and Edwardian terraces of Kilburn, Willesden and Harlesden, through the planned streets of Queen's Park, to the interwar semi-detached suburbia of Wembley, Kingsbury and Sudbury. Side-return and rear extensions and hip-to-gable loft conversions are the borough's most requested projects, and the housing character shifts noticeably across it — from party-wall-sensitive terraced grids to the consistent interwar semi character the council expects extensions to respect toward Wembley and Kingsbury. Conservation control around Queen's Park, Mapesbury and Sudbury Court, and in Roundwood, Brondesbury and Willesden Green, tightens design where it applies.
For the borough's abundant terraces and interwar semis, single-storey side-returns and hip-to-gable or dormer lofts frequently qualify as permitted development within the volume limits, so a full application isn't always needed. But Brent operates a borough-wide Article 4 direction removing permitted development for change of use to an HMO (C3 to C4), meaning any conversion to a house in multiple occupation needs a full application anywhere in the borough, and conservation areas such as Queen's Park, Mapesbury and Sudbury Court restrict what would otherwise be permitted. We take a validation-first approach, confirming the designation for your street and, where a scheme qualifies, evidencing permitted development with a Lawful Development Certificate before drawing.
We prepare Brent planning and building-regulations drawings to the council's householder and validation standards across Wembley, Willesden, Kilburn, Harlesden, Neasden and Sudbury, producing the same council-accepted drawings an architect would — usually at around 30% less. The fee is fixed and agreed before we start, drawings typically turn around in about seven days, and we redraw free until Brent approves. Most householder applications are determined within the statutory eight-week period once validated, and because the dense terraced streets are party-wall-sensitive the commonest delay is a drawing query, so a complete submission to the council's householder guidance keeps the application moving.
Planning in Brent: what to know before you apply
Brent operates a borough-wide Article 4 direction removing permitted development rights for HMO conversions, and controls design within conservation areas such as Queen's Park, Mapesbury and Sudbury Court. For the borough's abundant terraces and interwar semis, side-returns and hip-to-gable lofts frequently qualify as permitted development — we confirm the designation for your street before drawing.

Planning Permission for Brent homes: the package and the process
Every planning permission we prepare for a Brent property is drawn to London Borough of Brent’s validation standards and tuned to the local constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Securing planning permission in London means navigating borough-specific design guidance, conservation areas, Article 4 directions and a validation checklist that differs from one council to the next. DrawingsDirect prepares the existing and proposed drawings your local planning authority needs, submits them through the Planning Portal, and manages the application to a decision — for a fixed fee agreed before we start.
Because we are MCIAT-chartered architectural technologists rather than a general architecture practice, you get the same council-accepted drawings and professional accountability at a typically lower fee, with structural coordination handled in-house.
Do I need planning permission for an extension in London?
Many single-storey rear extensions, loft conversions and outbuildings fall under permitted development rights and do not need a full planning application — but London's dense housing stock, conservation areas and Article 4 directions frequently withdraw those rights. Before you pay for a full application, we check your property against the current permitted development thresholds and your borough's local constraints.
Where permitted development applies, we recommend a Lawful Development Certificate instead of full planning — it is faster, cheaper and gives you a legal document confirming the work was lawful. Where a full application is genuinely required, we prepare it properly the first time.
Permitted development vs a full planning application
Permitted development lets you build within defined volumetric limits without committee review. A full householder application is assessed against the borough's local plan for scale, daylight, neighbour impact and design. We advise which route your project qualifies for and why.
Article 4 directions and conservation areas
If your home sits in a conservation area or under an Article 4 direction, permitted development rights are often removed — meaning even modest changes need consent. Each borough page lists the local directions and conservation areas we routinely design around.
How do you apply for planning permission through the London Planning Portal?
We manage the full lifecycle of your submission — survey, drawings, supporting documents and officer liaison — so you never have to decode a validation checklist yourself.
Phase 1 — existing and proposed site surveys
A laser-measured survey captures your property exactly, so existing and proposed drawings match reality millimetre for millimetre.
Phase 2 — technical drawing package
Site location plan, block plan, floor plans, elevations and sections drawn to your borough's scale and formatting requirements, with a design and access statement where needed.
Phase 3 — liaison with the planning officer
We answer the council's queries, negotiate amendments, and redraw free until the decision lands.
