Planning Permission in Southall UB2
Fixed-fee, MCIAT-chartered planning permission for Southall (UB2) homeowners — London Borough of Ealing validation and local constraints handled from the start.
In Southall (UB2) we produce planning and building-regulation drawings for rear extensions, side-return kitchens and loft conversions on the area's Edwardian and interwar homes.
Where a plot sits within or near the Canalside conservation area we check the boundary and the canal-frontage constraints first, then advise whether the work is permitted development or needs a full planning application.
Planning in Southall (UB2): what to know before you apply
Most UB2 homes away from the canal retain permitted-development rights for rear extensions and lofts. Plots inside the Canalside conservation area face tighter control on anything visible from the towpath, and the Blue Ribbon/SINC designation adds ecology checks near the water.
Typical Southall housing stock
South Southall (UB2) is largely Edwardian and interwar terraces and semis around Norwood Green and Tentelow Lane, with the Grand Union Canal corridor forming the Canalside conservation area along its southern edge.

Planning Permission for Southall (UB2) 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 |
| Full Planning pack | 10–14 working days | Council liaison & design statement | £1,600–£2,400 |
| Planning + Building Regs pack | 14–21 working days | Structural calculations included | £2,200–£3,850 |
