Single-storey, double-storey, rear and side extension drawings for Tewkesbury homes — measured to Tewkesbury Borough Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Tewkesbury Borough Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Tewkesbury contains Bishop's Cleeve Conservation Area, Buckland Conservation Area, Dumbleton Conservation Area conservation areas (Bishop's Cleeve Conservation Area designated 1979), 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.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Tewkesbury carries at least one Article 4 direction, and conservation areas including Bishop's Cleeve Conservation Area, Buckland Conservation Area and Dumbleton Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Tewkesbury is determined against an 8-week statutory target.
Bishop's Cleeve (conservation area designated in 1979), Buckland (conservation area designated in 1977), Dumbleton (conservation area designated in 2001), Great Washbourne (conservation area designated in 2001), Gretton (conservation area designated in 1975), Laverton (conservation area designated in 1977), Snowshill (conservation area designated in 1971), Stanton (conservation area designated in 1971), Cleeve St Michael's (ward of Tewkesbury), Tewkesbury South (ward of Tewkesbury), Winchcombe (ward of Tewkesbury), Cleeve Hill (ward of Tewkesbury) and Isbourne (ward of Tewkesbury) — these are the Tewkesbury pockets our drawings cover most. Heritage designations here include Bishop's Cleeve Conservation Area, Buckland Conservation Area, Dumbleton Conservation Area, Great Washbourne Conservation Area, Gretton Conservation Area, Laverton Conservation Area, Snowshill Conservation Area and Stanton Conservation Area. Tewkesbury Borough Council weighs each proposal against the adopted Tewkesbury local plan and Tewkesbury Borough Council's design guidance for householder work, where the 13,980 homes here are 11% pre-1900, 9% 1965-1972, 9% 1955-1964, 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 (11% of 13,980 homes), late-1960s and early-1970s houses (9%) and late-1950s and early-1960s houses (9%).
Before anything is drawn we check your address against the designations that apply in Tewkesbury: Bishop's Cleeve (conservation area designated in 1979), Buckland (conservation area designated in 1977), Dumbleton (conservation area designated in 2001), Great Washbourne (conservation area designated in 2001), Gretton (conservation area designated in 1975), Laverton (conservation area designated in 1977), Snowshill (conservation area designated in 1971) and Stanton (conservation area designated in 1971). Inside those boundaries permitted development is curtailed and Tewkesbury Borough 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, Tewkesbury takes in Cleeve St Michael's, Tewkesbury South, Winchcombe, Cleeve Hill and Isbourne. Tewkesbury Borough Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in the district.
On stock, Tewkesbury is Victorian and earlier houses (11% of 13,980 homes), late-1960s and early-1970s houses (9%) and late-1950s and early-1960s houses (9%) — 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. Tewkesbury Borough Council decided 380 householder applications in the latest published year and granted 93%, with 57% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Tewkesbury 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.
Tewkesbury Borough Council also decides for Cleeve St Michael's, Tewkesbury South, Winchcombe, Cleeve Hill and Isbourne, so a decision in Tewkesbury 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 Ashleworth Green Article 4 Direction, Buckland Article 4 Direction, Church End Twyning Article 4 Direction and Dumbleton Article 4 Direction. 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.

Tewkesbury 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 13,980 homes), late-1960s and early-1970s houses (9%) and late-1950s and early-1960s houses (9%), 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. Tewkesbury Borough Council judges every one of them against the adopted Tewkesbury local plan and Tewkesbury Borough Council's design guidance for householder work, 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. Tewkesbury contains Bishop's Cleeve Conservation Area, Buckland Conservation Area, Dumbleton Conservation Area conservation areas (Bishop's Cleeve Conservation Area designated 1979), 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.
Tewkesbury also protects whole streets — Bishop's Cleeve Conservation Area, Buckland Conservation Area, Dumbleton Conservation Area, Great Washbourne Conservation Area, Gretton Conservation Area, Laverton Conservation Area, Snowshill Conservation Area and Stanton Conservation Area among them. Tewkesbury Borough Council has 11 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in the district. 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 Tewkesbury 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 Tewkesbury Borough Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Tewkesbury Borough 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 Tewkesbury Borough Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Tewkesbury Borough Council granted 93% of 380 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 Bishop's Cleeve, Buckland and Dumbleton, 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 13,980 homes), a side-return infill frequently pairs with it to square off the plan; on wider late-1950s and early-1960s houses (9%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 13,980 homes here are 11% pre-1900, 9% 1965-1972, 9% 1955-1964, 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 Tewkesbury Borough 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 Tewkesbury projects come up most often:

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