Single-storey, double-storey, rear and side extension drawings for Vale of White Horse homes — measured to Vale of White Horse District Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Vale of White Horse District Council granted 96% of the householder planning decisions it made in its latest published year — 9 points above the 87% England-wide householder average. Vale of White Horse contains Abingdon - Albert Park Conservation Area, Appleton Conservation Area, Ardington and East Lockinge Conservation Area conservation areas (Abingdon - Albert Park Conservation Area designated 1975), 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) and postwar (1945–1970) 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. In conservation areas such as Abingdon - Albert Park Conservation Area, Appleton Conservation Area and Ardington and East Lockinge Conservation Area those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Vale of White Horse is determined against an 8-week statutory target.
Abingdon - Albert Park (conservation area designated in 1975), Appleton (conservation area designated in 1969), Ardington and East Lockinge (conservation area designated in 1970), Baulking (conservation area designated in 1971), Blewbury (conservation area designated in 1970), Buckland (conservation area designated in 1971), Charney Bassett (conservation area designated in 1978), Childrey (conservation area designated in 1970), Abingdon Fitzharris (ward of Vale of White Horse), Ridgeway (ward of Vale of White Horse), Stanford (ward of Vale of White Horse), Blewbury & Harwell (ward of Vale of White Horse), Drayton (ward of Vale of White Horse), Sutton Courtenay (ward of Vale of White Horse), Thames (ward of Vale of White Horse) and Faringdon (ward of Vale of White Horse) — these are the Vale of White Horse pockets our drawings cover most. Heritage designations here include Abingdon - Albert Park Conservation Area, Appleton Conservation Area, Ardington and East Lockinge Conservation Area, Baulking Conservation Area, Blewbury Conservation Area, Buckland Conservation Area, Charney Bassett Conservation Area and Childrey Conservation Area. Vale of White Horse District Council weighs each proposal against Vale of White Horse District Council's development plan and the design policies it applies to householder applications, where the 36,310 homes here are 11% pre-1900, 8% 1955-1964, 6% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building, over Victorian and earlier houses (11% of 36,310 homes), late-1950s and early-1960s houses (8%) and late-1960s and early-1970s houses (6%).
Vale of White Horse's designated heritage is specific, and it is the first thing we check against your address: Abingdon - Albert Park (conservation area designated in 1975), Appleton (conservation area designated in 1969), Ardington and East Lockinge (conservation area designated in 1970), Baulking (conservation area designated in 1971), Blewbury (conservation area designated in 1970), Buckland (conservation area designated in 1971), Charney Bassett (conservation area designated in 1978) and Childrey (conservation area designated in 1970). Inside those boundaries permitted development is curtailed and Vale of White Horse District 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, Vale of White Horse takes in Abingdon Fitzharris, Ridgeway, Stanford, Blewbury & Harwell, Drayton, Sutton Courtenay, Thames and Faringdon. No Article 4 direction is recorded for Vale of White Horse District Council, but the district's 8 conservation areas still limit permitted development on those streets.
On stock, Vale of White Horse is Victorian and earlier houses (11% of 36,310 homes), late-1950s and early-1960s houses (8%) and late-1960s and early-1970s houses (6%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Vale of White Horse District Council decided 563 householder applications in the latest published year and granted 96%, with 57% issued inside the eight-week target. Those are the numbers our drawings are prepared against.
The full build-period split for Vale of White Horse runs pre-1900 3% (190 homes), 1900-1918 0% (30 homes), 1919-1929 0% (10 homes), 1930-1939 6% (350 homes), 1945-1954 3% (170 homes), 1955-1964 30% (1,850 homes), 1965-1972 33% (1,990 homes), 1973-1982 4% (260 homes), 1983-1992 5% (310 homes), 1993-1999 4% (220 homes) and 2000-2008 3% (170 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.
Vale of White Horse District Council also decides for Abingdon Fitzharris, Ridgeway, Stanford, Blewbury & Harwell, Drayton, Sutton Courtenay, Thames and Faringdon, so a decision in Vale of White Horse 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.

Vale of White Horse homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from Victorian and earlier houses (11% of 36,310 homes), late-1950s and early-1960s houses (8%) and late-1960s and early-1970s houses (6%), 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. Vale of White Horse District Council judges every one of them against Vale of White Horse District 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. Vale of White Horse contains Abingdon - Albert Park Conservation Area, Appleton Conservation Area, Ardington and East Lockinge Conservation Area conservation areas (Abingdon - Albert Park Conservation Area designated 1975), 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.
Vale of White Horse also protects whole streets — Abingdon - Albert Park Conservation Area, Appleton Conservation Area, Ardington and East Lockinge Conservation Area, Baulking Conservation Area, Blewbury Conservation Area, Buckland Conservation Area, Charney Bassett Conservation Area and Childrey Conservation Area among them. No Article 4 direction is recorded for Vale of White Horse District Council, but the district's 8 conservation areas still limit permitted development 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 Vale of White Horse 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 Vale of White Horse District Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Vale of White Horse District 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 Vale of White Horse District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Vale of White Horse District Council granted 96% of 563 householder decisions in the year to 31 March 2026, 57% of them inside eight weeks. 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 Abingdon - Albert Park, Appleton and Ardington and East Lockinge, 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 earlier houses (11% of 36,310 homes), a side-return infill frequently pairs with it to square off the plan; on wider late-1960s and early-1970s houses (6%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 36,310 homes here are 11% pre-1900, 8% 1955-1964, 6% 1965-1972, 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 Vale of White Horse District 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.

The right extension in Vale of White Horse 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 Vale of White Horse District 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 Abingdon - Albert Park Conservation Area and Appleton Conservation Area and Article 4 directions can remove permitted-development rights.
A fixed process built around how Vale of White Horse District Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Vale of White Horse 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 Vale of White Horse District 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 Vale of White Horse District 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 Vale of White Horse District 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 Vale of White Horse you will need to apply to Vale of White Horse District 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 Abingdon - Albert Park Conservation Area and Appleton Conservation Area.
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 Vale of White Horse District Council and a neighbour-consultation period, and it does not apply on designated land such as Vale of White Horse'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 Vale of White Horse District 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 Vale of White Horse 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. Vale of White Horse District 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 Vale of White Horse District Council's building control or an approved inspector can sign the work off.
