Perivale (UB6) is a well-preserved 1930s suburb of matching semis on curving avenues, where the bread-and-butter work is rear kitchen extensions, hip-to-gable loft conversions and rear dormers. The uniformity of the streetscape means Ealing's officers care about how a proposal reads against its neighbours, so faithful detailing matters more here than in a mixed-age street.

Perivale also sits in the orbit of the Art Deco Hoover Building on Western Avenue and the green ridge of Horsenden Hill, and the Canalside conservation area clips its north-west edge. We design extensions that echo the original bay, render and roof pitch, and we check tree cover and the canal-side boundary so schemes reach Ealing's approval standard first time.

Planning in Perivale (UB6): what to know before you apply

No published householder Article 4 direction in Perivale, so most householder work proceeds under permitted development or a standard Ealing application. Homes near the Canalside conservation area or backing onto Horsenden Hill's open space face tighter scrutiny on materials, roof form and tree protection.

Typical Perivale housing stock

Perivale is a planned interwar suburb of consistent 1930s semis and short terraces, many with curved bays, rendered gables and hipped tiled roofs, arranged on gently curving crescents. Streets rising towards Horsenden Hill keep deep rear gardens well suited to single-storey extensions and loft dormers.

House Extension Drawings for Perivale (UB6) homes: the package and the process

Every house extension drawings we prepare for an Perivale property is drawn to London Borough of Ealing’s validation standards and tuned to the UB6 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

A well-drawn extension adds space and value while sailing through the council; a poorly-drawn one triggers objections and refusals. DrawingsDirect draws rear, side-return, wraparound, double-storey and basement extensions for London homes — sized to your borough's tolerances, with daylight and neighbour impact considered before the planners raise them.

Which extension types do you draw?

Every London extension is shaped by the plot, the neighbours and the borough's design guidance. We draw them all.

Rear extension

A single-storey rear extension is often permitted development within depth limits — ideal for an open-plan kitchen-diner.

Side-return

Fills the alley beside a Victorian terrace, widening the ground floor without losing garden.

Wraparound

Combines a rear and side-return extension for a transformative ground floor, usually needing planning permission.

Double-storey

Adds space above and below, subject to tighter scale and neighbour-impact scrutiny.

Basement

Creates space downward where footprint is limited, with structural and party-wall care.

Do I need planning permission for a house extension in London?

Single-storey rear extensions within permitted development limits (up to 6m for terraced/semi-detached homes under the larger-home scheme, subject to neighbour consultation) may not need a full application. Wraparounds, double-storeys and anything in a conservation area usually do. We assess your plot and recommend the right route before drawing.

FAQ

House Extension Drawings in Perivale UB6 — FAQs

How far can I extend without planning permission in London?+
Under permitted development, single-storey rear extensions can reach 3m (terraced/semi) or 4m (detached), or up to 6–8m under the prior-approval larger-home scheme — but conservation areas and Article 4 directions can remove these rights. We check your property first.
Do extension drawings include structural calculations?+
Our full package includes structural drawings and calculations coordinated in-house, so your builder can price and build without waiting on an engineer.
How long do extension drawings take?+
Typically about 7 days from survey to a full drawing set delivered to your online portal.
Will my rear extension need a party wall agreement?+
If you build up to or on a shared boundary, excavate near a neighbour's foundations, or cut into a party wall for a steel, the Party Wall etc. Act 1996 usually applies. Our drawings show the works clearly so a party wall surveyor — or your neighbour — can see exactly what is proposed, which keeps that process quick.
Can I extend a house in a conservation area?+
Yes, but conservation areas and Article 4 directions commonly remove permitted development for rear and side extensions, so the work needs a full householder application designed to the council's heritage guidance. We confirm your property's designation before recommending a route.
Do I need planning permission for a rear extension in Ealing?+
Many Ealing semis and terraces keep permitted development rights for a single-storey rear extension, so a full application isn't always needed. But the borough-wide Article 4 direction on HMO conversions, and conservation areas such as Bedford Park and Pitshanger, remove or restrict those rights in places. We check your address against the designations first and, where it qualifies, confirm permitted development with a Lawful Development Certificate.
What extra control applies in Bedford Park?+
Bedford Park is one of West London's most tightly controlled conservation areas, with detailed control over materials, rooflines, windows and front elevations. A standard permitted-development dormer or cladding change usually won't apply; instead we design to the area's Arts-and-Crafts character and prepare a full householder application with the elevations and materials the council expects — the reliable route to approval there.
How long does Ealing Council take to decide a householder application?+
Ealing determines most householder applications within the statutory eight-week period once they are validated. The commonest cause of delay is a validation query over missing or inconsistent drawings, so we prepare Ealing submissions to the council's validation checklist — correctly scaled existing and proposed plans, elevations and a location plan — to avoid that back-and-forth.
Can you help with a loft conversion on a 1930s Ealing semi?+
Yes. Ealing's Metro-land semis in Perivale, Greenford and Northolt suit hip-to-gable and dormer loft conversions, which frequently qualify as permitted development on semi-detached homes within the volume limits. We confirm eligibility against those limits and any Article 4 or conservation constraint, then produce the planning and building-regulations drawings.
How much do planning drawings cost in Ealing?+
We work to a fixed fee agreed before we start, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Ealing grants approval. The exact figure depends on the project — a single-storey rear extension differs from a double-storey or a loft — so we quote once we understand your scheme rather than on an open-ended hourly basis.
