Single-storey, double-storey, rear and side extension drawings for Newbury Greenham homes — measured to West Berkshire Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
West Berkshire Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Newbury Greenham contains Newbury Town Centre, Stroud Green conservation areas (Newbury Town Centre designated 1981), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Newbury Greenham carries at least one Article 4 direction, and conservation areas including Newbury Town Centre and Stroud Green remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Newbury Greenham is determined against an 8-week statutory target.
Newbury Town Centre (conservation area designated in 1981), Stroud Green (conservation area designated in 1971), Greenham (civil parish within Newbury Greenham) and Newbury (civil parish within Newbury Greenham) — these are the Newbury Greenham pockets our drawings cover most. Heritage designations here include Newbury Town Centre and Stroud Green. West Berkshire Council weighs each proposal against West Berkshire Council's development plan and the design policies it applies to householder applications, where the 5,860 homes here are 14% 2000-2008, 12% 1973-1982, 11% pre-1900, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 2000s building and shallow trussed roofs typical of 1970s building, over 2000s houses and apartments (14% of 5,860 homes), 1970s and early-1980s houses (12%) and Victorian and earlier houses (11%).
Newbury Greenham's designated heritage is specific, and it is the first thing we check against your address: Newbury Town Centre (conservation area designated in 1981) and Stroud Green (conservation area designated in 1971). Inside those boundaries permitted development is curtailed and West Berkshire Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
Beyond the designated areas, Newbury Greenham takes in Greenham and Newbury. West Berkshire Council has 9 recorded Article 4 directions — check the address before assuming PD applies in Newbury Greenham.
On stock, Newbury Greenham is 2000s houses and apartments (14% of 5,860 homes), 1970s and early-1980s houses (12%) and Victorian and earlier houses (11%) — which is why trussed-rafter roofs typical of 2000s building and shallow trussed roofs typical of 1970s building govern what a loft or rear projection can realistically be. West Berkshire Council decided 606 householder applications in the latest published year and granted 93%, with 57% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Newbury Greenham runs pre-1900 11% (630 homes), 1900-1918 4% (220 homes), 1919-1929 1% (60 homes), 1930-1939 2% (130 homes), 1945-1954 1% (40 homes), 1955-1964 6% (340 homes), 1965-1972 8% (470 homes), 1973-1982 12% (720 homes), 1983-1992 5% (310 homes), 1993-1999 4% (230 homes) and 2000-2008 14% (800 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
West Berkshire Council also decides for Aldermaston, Basildon, Bradfield, Chieveley & Cold Ash, Downlands, Hungerford & Kintbury, Lambourn and Newbury Clay Hill, so a decision in Newbury Greenham sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.
The Article 4 directions recorded for this council include Fords Farm Estate, Land Fronting 1085-1107 Oxford Road, Tilehurst, Land at East Garston and Land at Theobald Drive, Tilehurst. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

Newbury Greenham homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from 2000s houses and apartments (14% of 5,860 homes), 1970s and early-1980s houses (12%) and Victorian and earlier houses (11%), 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. West Berkshire Council judges every one of them against West Berkshire Council's development plan and the design policies it applies to householder applications, 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. Newbury Greenham contains Newbury Town Centre, Stroud Green conservation areas (Newbury Town Centre designated 1981), so materials, fenestration and roof form are assessed against the appraisal, so we design around it from the first sketch rather than discover it at validation.
Newbury Greenham also protects whole streets — Newbury Town Centre and Stroud Green among them. West Berkshire Council has 9 recorded Article 4 directions — check the address before assuming PD applies in Newbury Greenham. 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 Newbury Greenham 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 West Berkshire Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships West Berkshire 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 West Berkshire Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. West Berkshire Council granted 93% of its householder applications in the year to 31 March 2026, and Newbury Town Centre shapes what is approved here. 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 Newbury Town Centre, Stroud Green and Greenham, 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 2000s houses and apartments (14% of 5,860 homes), a side-return infill frequently pairs with it to square off the plan; on wider victorian and earlier houses (11%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 5,860 homes here are 14% 2000-2008, 12% 1973-1982, 11% pre-1900, which is what sets the realistic roof and rear-projection options. 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 West Berkshire 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 Newbury Greenham projects come up most often:

The right extension in Newbury Greenham 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 West Berkshire 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 Newbury Town Centre and Stroud Green and Article 4 directions can remove permitted-development rights.
A fixed process built around how West Berkshire Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Newbury Greenham 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 West Berkshire 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 West Berkshire 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 West Berkshire 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 Newbury Greenham you will need to apply to West Berkshire 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 Newbury Town Centre and Stroud Green.
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 West Berkshire Council and a neighbour-consultation period, and it does not apply on designated land such as Newbury Greenham'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 West Berkshire 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. This applies to your Newbury Greenham address specifically.
A householder planning application in Newbury Greenham 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. West Berkshire 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 West Berkshire Council's building control or an approved inspector can sign the work off. This applies to your Newbury Greenham address specifically.
Every house and brief is different, so we price each Newbury Greenham extension individually and send a fixed, no-obligation quote back within one working day.
