White City (W12) is one of west London's most contrasting districts — the planned interwar Old Oak & Wormholt cottage estate on one side, the vast regeneration of the former BBC and Westfield lands on the other, all in the London Borough of Hammersmith & Fulham. Projects here range from careful roof and rear extensions on the cottage-estate terraces to alterations and fit-outs in the new and converted flats.

The Old Oak & Wormholt conservation area protects the consistent interwar terraces, where roof and frontage changes are sensitive, while the Wood Lane frontage and the White City regeneration framework set the tone for the redevelopment lands. Because so much of the housing is leasehold, alterations often need freeholder consent and party-wall agreement alongside planning, so we establish the property type and any conservation boundary before drawing to Hammersmith & Fulham's guidance.

Planning in White City (W12): what to know before you apply

W12 White City has no published householder Article 4 direction, but the Old Oak & Wormholt conservation area protects the interwar cottage estate, where roof and frontage changes are controlled, and the Wood Lane regeneration framework governs the redevelopment lands. Flats and estate housing do not carry the permitted development rights of houses, so much of the alteration work here is assessed as full planning alongside freeholder consent.

Typical White City housing stock

A district of contrasts — the interwar Old Oak & Wormholt cottage estate and surrounding council-built housing set against the large-scale regeneration of the former BBC and Westfield lands, so the stock spans modest cottage terraces and a growing number of new-build and converted flats.

House Extension Drawings for White City (W12) homes: the package and the process

Every house extension drawings we prepare for an White City property is drawn to London Borough of Hammersmith & Fulham’s validation standards and tuned to the W12 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 White City W12 — 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 side-return extension in Hammersmith & Fulham?+
On the Victorian and Edwardian terraces of Fulham and Shepherd's Bush a single-storey side-return or rear extension can fall within permitted development, so a full application isn't always required. Conservation areas across Fulham, Brackenbury and Ravenscourt Park, and the Peterborough Estate, restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate.
Will I need a Basement Impact Assessment for a basement in Hammersmith & Fulham?+
Likely, yes. The council applies a basement policy requiring a basement impact assessment for below-ground works, covering structural stability, drainage and groundwater. Basement extensions are common on these terraces, so if you are considering one we flag the requirement early and coordinate the structural input so the application is complete when submitted.
What is special about the Peterborough Estate 'Lion houses'?+
The Peterborough Estate's distinctive red-brick 'Lion houses' carry strong conservation control over their external character, so alterations are expected to respect the estate's materials and detailing. We design to that character and prepare a full householder application where permitted development doesn't apply, which is the reliable route to approval there.
How long does Hammersmith & Fulham take to decide?+
The council determines most householder applications within the statutory eight-week period once validated; basement and conservation cases can involve additional consultation. Because the terraces are party-wall-sensitive, we prepare submissions to the borough's residential extension and basement guidance to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Hammersmith & Fulham?+
We agree a fixed fee before we start, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until the council approves. A side-return, a loft and a basement differ in complexity, so we quote once we have seen your address and project rather than by the hour.
