Single-storey, double-storey, rear and side extension drawings for Ealing homes — measured to Ealing Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Ealing Council granted 85% of the householder planning decisions it made in its latest published year — 2 points below the 87% England-wide householder average. Case officers apply the borough's daylight and outlook tests strictly across tight Victorian plot lines, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Ealing Council needs a full application. Ealing carries at least one Article 4 direction, and conservation areas including Bedford Park, Ealing Common and Ealing Green remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Ealing is determined against an 8-week statutory target.
Ealing Broadway (red-brick Victorian and Edwardian terraces around the town centre), Hanwell (Edwardian terraces and the Hanwell Village Green conservation area), Northfields (Edwardian streets around Lammas Park), West Ealing (mixed Victorian terraces and converted flats), Greenford (interwar semi-detached estates) and Perivale (1930s Metroland semis with hipped roofs) — these are the Ealing pockets our drawings cover most. Heritage designations here include Bedford Park, Ealing Common, Ealing Green, Hanwell Village Green and Northfields (Lammas Park). Ealing Council weighs each proposal against Ealing Local Plan and the Residential Extensions and Alterations SPD, where roof bulk on paired 1930s houses is a recurring refusal reason. Converted terraces are common across West Ealing and Hanwell, and flats and maisonettes have no householder permitted-development rights.. On roofs the borough is London butterfly / valley roofs on the terraces and hipped roofs on the 1930s semis, over Victorian and Edwardian terraces, interwar semi-detached houses and converted period flats.
Ealing homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from Victorian and Edwardian terraces, interwar semi-detached houses and converted period flats, so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Ealing Council judges every one of them against Ealing Local Plan and the Residential Extensions and Alterations SPD, weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. Case officers apply the borough's daylight and outlook tests strictly across tight Victorian plot lines, so we design around it from the first sketch rather than discover it at validation.
Ealing also protects whole streets — Bedford Park, Ealing Common, Ealing Green, Hanwell Village Green and Northfields (Lammas Park) among them. Bedford Park — shared with Hounslow — carries a long-established Article 4 direction, and several other Ealing conservation areas remove permitted-development rights, so PD can never be assumed on those streets. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.
Plenty of Ealing extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Ealing Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Ealing Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is Ealing Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Ealing grants around the London average of householder applications, with roof bulk on paired 1930s houses and neighbour daylight across narrow plots the most common sticking points. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across Ealing Broadway, Hanwell and Northfields, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's victorian and edwardian terraces, a side-return infill frequently pairs with it to square off the plan; on wider converted period flats, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
Roof bulk on paired 1930s houses is a recurring refusal reason. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Ealing Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.
We draw extensions on every street in the borough. A few of the neighbourhoods where Ealing projects come up most often:

The right extension in Ealing depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What Ealing Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Bedford Park and Ealing Common and Article 4 directions can remove permitted-development rights.
A fixed process built around how Ealing Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Ealing postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Ealing Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Ealing Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Ealing Council issues its decision.
Not always. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development. In Ealing you will need to apply to Ealing Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Bedford Park and Ealing Common.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Ealing Council and a neighbour-consultation period, and it does not apply on designated land such as Ealing's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Ealing Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings.
A householder planning application in Ealing runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Ealing Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Ealing Council's building control or an approved inspector can sign the work off.
Every house and brief is different, so we price each Ealing extension individually and send a fixed, no-obligation quote back within one working day.
