Planning Permission in Brixton Hill SW2
Fixed-fee, MCIAT-chartered planning permission for Brixton Hill (SW2) homeowners — London Borough of Lambeth validation and local constraints handled from the start.
Brixton Hill (SW2) runs up the ridge between Brixton and Streatham Hill in Lambeth, and its Victorian terraces and villas make side-return, rear and loft projects the most common work here. The Rush Common & Brixton Hill conservation area governs frontages and rooflines along much of the hill, so where a property sits relative to that boundary shapes how an extension or loft is designed and assessed.
SW2 also carries an unusual historic control: the Rush Common Act restricts building on the old open land in front of houses on the east side of Brixton Hill, which can affect front additions and boundary work on those plots. We check both the conservation boundary and the Rush Common frontage before recommending a permitted-development or full-application route, and prepare the drawings to Lambeth's residential design and validation standards.
Planning in Brixton Hill (SW2): what to know before you apply
SW2 has no borough-wide householder Article 4 direction, so many Brixton Hill houses retain permitted development rights — but the Rush Common & Brixton Hill conservation area is the exception, and the historic Rush Common Act frontage restriction is a genuine local quirk on the east side of the hill that we check before drawing.
Typical Brixton Hill housing stock

Planning Permission for Brixton Hill (SW2) homes: the package and the process
A householder application is refused validation far more often than it is refused permission, and almost always for the same reasons: a location plan at the wrong scale, no red line around the application site, a missing ownership certificate, or elevations that do not show every face of the building affected. We prepare the full submission set — location plan, block plan, existing and proposed floor plans, elevations and sections — so the case officer receives a complete case on day one.
Once the application is live we stay on it. Officers routinely come back with questions about materials, boundary treatment or a dimension they cannot read off the drawings, and a fast, drawn answer is usually the difference between a decision inside the statutory period and a request to withdraw and resubmit.
Which route applies is decided by the building before it is decided by policy. A house that has never been extended usually has allowances left to use; a flat, a listed building or a home in a conservation area often has none, and the same drawing set then has to make a design case rather than a compliance one.
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.
How long does planning permission take, and what does it cost?
Drawings are typically ready within 7 days of survey. Your council then has a statutory 8 weeks to decide a householder application. Our drawing fees are fixed and quoted upfront — the table below shows typical packages.
| Package | Production window | Compliance layer | Typical fee |
|---|---|---|---|
| Permitted Development pack | 7–10 working days | Lawful Development Certificate submission | £950–£1,450 |
