Single-storey, double-storey, rear and side extension drawings for Wychavon homes — measured to Wychavon District Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Wychavon District Council granted 91% of the householder planning decisions it made in its latest published year — 4 points above the 87% England-wide householder average. Wychavon contains Abberton, Abbots Moreton, Aldington conservation areas, 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.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. In conservation areas such as Abberton, Abbots Moreton and Aldington those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Wychavon is determined against an 8-week statutory target.
Abberton (designated conservation area), Abbots Moreton (designated conservation area), Aldington (designated conservation area), Ashton under Hill (designated conservation area), Atch Lench (designated conservation area), Badsey (designated conservation area), Beckford (designated conservation area), Birlingham (designated conservation area), Badsey & Aldington (ward of Wychavon), Bowbrook (ward of Wychavon), Bredon (ward of Wychavon), Bredon Hill (ward of Wychavon), Bretforton & Offenham (ward of Wychavon), Dodderhill (ward of Wychavon), Droitwich East (ward of Wychavon) and Eckington (ward of Wychavon) — these are the Wychavon pockets our drawings cover most. Heritage designations here include Abberton, Abbots Moreton, Aldington, Ashton under Hill, Atch Lench, Badsey, Beckford and Birlingham. Wychavon District Council weighs each proposal against Wychavon District Council's development plan and the design policies it applies to householder applications, where the 23,140 homes here are 20% pre-1900, 9% 1965-1972, 5% 1973-1982, 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-pitched roofs and integral garages typical of that period's building, over Victorian and earlier houses (20% of 23,140 homes), late-1960s and early-1970s houses (9%) and 1970s and early-1980s houses (5%).
What is permitted in Wychavon turns on designation first, so that is where we start: Abberton (designated conservation area), Abbots Moreton (designated conservation area), Aldington (designated conservation area), Ashton under Hill (designated conservation area), Atch Lench (designated conservation area), Badsey (designated conservation area), Beckford (designated conservation area) and Birlingham (designated conservation area). Inside those boundaries permitted development is curtailed and Wychavon 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, Wychavon takes in Badsey & Aldington, Bowbrook, Bredon, Bredon Hill, Bretforton & Offenham, Dodderhill, Droitwich East and Eckington. No Article 4 direction is recorded for Wychavon District Council, but the district's 8 conservation areas still limit permitted development on those streets.
On stock, Wychavon is Victorian and earlier houses (20% of 23,140 homes), late-1960s and early-1970s houses (9%) and 1970s and early-1980s houses (5%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow-pitched roofs and integral garages typical of that period's building govern what a loft or rear projection can realistically be. Wychavon District Council decided 440 householder applications in the latest published year and granted 91%, with 88% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Wychavon 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.
Wychavon District Council also decides for Badsey & Aldington, Bowbrook, Bredon, Bredon Hill, Bretforton & Offenham, Dodderhill, Droitwich East and Eckington, so a decision in Wychavon 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.

Wychavon 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 (20% of 23,140 homes), late-1960s and early-1970s houses (9%) and 1970s and early-1980s houses (5%), 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. Wychavon District Council judges every one of them against Wychavon 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. Wychavon contains Abberton, Abbots Moreton, Aldington conservation areas, 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.
Wychavon also protects whole streets — Abberton, Abbots Moreton, Aldington, Ashton under Hill, Atch Lench, Badsey, Beckford and Birlingham among them. No Article 4 direction is recorded for Wychavon 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 Wychavon 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 Wychavon 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 Wychavon 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 Wychavon District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Wychavon District Council granted 91% of 440 householder decisions in the year to 31 March 2026, 88% 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 Abberton, Abbots Moreton and Aldington, 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 (20% of 23,140 homes), a side-return infill frequently pairs with it to square off the plan; on wider 1970s and early-1980s houses (5%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 23,140 homes here are 20% pre-1900, 9% 1965-1972, 5% 1973-1982, 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 Wychavon 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.
We draw extensions on every street in the borough. A few of the neighbourhoods where Wychavon projects come up most often:

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