Single-storey, double-storey, rear and side extension drawings for Fosseridge homes — measured to Cotswold District Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Cotswold District Council granted 92% of the householder planning decisions it made in its latest published year — 5 points above the 87% England-wide householder average. Fosseridge contains Adlestrop Conservation Area, Bledington Conservation Area, Broadwell Conservation Area conservation areas (Adlestrop Conservation Area 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) 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. Fosseridge carries at least one Article 4 direction, and conservation areas including Adlestrop Conservation Area, Bledington Conservation Area and Broadwell Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Fosseridge is determined against an 8-week statutory target.
Adlestrop (conservation area designated in 1981), Bledington (conservation area designated in 1989), Broadwell (conservation area designated in 1977), Church Westcote (conservation area designated in 1989), Condicote (conservation area designated in 1989), Daylesford (conservation area designated in 1989), Donnington (conservation area designated in 1989), Evenlode (conservation area designated in 1981), Icomb (conservation area designated in 1972), Longborough (conservation area designated in 1990), Nether Westcote (conservation area designated in 1989), Oddington (conservation area designated in 1989), Sezincote (conservation area designated in 1990), Icomb (civil parish within Fosseridge), Longborough (civil parish within Fosseridge), Oddington (civil parish within Fosseridge), Sezincote (civil parish within Fosseridge), Westcote (civil parish within Fosseridge) and Adlestrop (civil parish within Fosseridge) — these are the Fosseridge pockets our drawings cover most. Heritage designations here include Adlestrop Conservation Area, Bledington Conservation Area, Broadwell Conservation Area, Church Westcote Conservation Area, Condicote Conservation Area, Daylesford Conservation Area, Donnington Conservation Area, Evenlode Conservation Area, Icomb Conservation Area, Longborough Conservation Area, Nether Westcote Conservation Area, Oddington Conservation Area and Sezincote Conservation Area. Cotswold District Council weighs each proposal against the adopted Cotswold local plan and Cotswold District Council's design guidance for householder work, where the 1,720 homes here are 40% pre-1900, 9% 1983-1992, 8% 1945-1954, 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 trussed-rafter roofs typical of 1980s building, over Victorian and earlier houses (40% of 1,720 homes), 1980s estate houses (9%) and early postwar houses (8%).
What is permitted in Fosseridge turns on designation first, so that is where we start: Adlestrop (conservation area designated in 1981), Bledington (conservation area designated in 1989), Broadwell (conservation area designated in 1977), Church Westcote (conservation area designated in 1989), Condicote (conservation area designated in 1989), Daylesford (conservation area designated in 1989), Donnington (conservation area designated in 1989), Evenlode (conservation area designated in 1981), Icomb (conservation area designated in 1972), Longborough (conservation area designated in 1990), Nether Westcote (conservation area designated in 1989), Oddington (conservation area designated in 1989) and Sezincote (conservation area designated in 1990). Inside those boundaries permitted development is curtailed and Cotswold 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, Fosseridge takes in Icomb, Longborough, Oddington, Sezincote, Westcote and Adlestrop. Cotswold District Council has 22 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in Fosseridge.
On stock, Fosseridge is Victorian and earlier houses (40% of 1,720 homes), 1980s estate houses (9%) and early postwar houses (8%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and trussed-rafter roofs typical of 1980s building govern what a loft or rear projection can realistically be. Cotswold District Council decided 592 householder applications in the latest published year and granted 92%, with 53% issued inside the eight-week target. We draw to that record rather than to a national average.
The full build-period split for Fosseridge runs pre-1900 40% (680 homes), 1900-1918 3% (50 homes), 1919-1929 1% (20 homes), 1930-1939 2% (40 homes), 1945-1954 8% (130 homes), 1955-1964 6% (100 homes), 1965-1972 6% (110 homes), 1973-1982 7% (120 homes), 1983-1992 9% (150 homes), 1993-1999 4% (70 homes) and 2000-2008 5% (80 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.
Cotswold District Council also decides for Abbey, Blockley, Bourton Vale, Bourton Village, Campden & Vale, Fairford North, Kemble and Moreton East, so a decision in Fosseridge 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 Article 4 (2) Direction Avening, Article 4 (2) Direction Bibury, Article 4 (2) Direction Blockley and Article 4 (2) Direction Bourton-On-The-Water. 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.

Fosseridge 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 (40% of 1,720 homes), 1980s estate houses (9%) and early postwar houses (8%), 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. Cotswold District Council judges every one of them against the adopted Cotswold local plan and Cotswold District 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. Fosseridge contains Adlestrop Conservation Area, Bledington Conservation Area, Broadwell Conservation Area conservation areas (Adlestrop Conservation Area 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.
Fosseridge also protects whole streets — Adlestrop Conservation Area, Bledington Conservation Area, Broadwell Conservation Area, Church Westcote Conservation Area, Condicote Conservation Area, Daylesford Conservation Area, Donnington Conservation Area, Evenlode Conservation Area, Icomb Conservation Area, Longborough Conservation Area, Nether Westcote Conservation Area, Oddington Conservation Area and Sezincote Conservation Area among them. Cotswold District Council has 22 recorded Article 4 directions, removing permitted development for rear and side extensions and roof enlargements such as dormers — check the address before assuming PD applies in Fosseridge. 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 Fosseridge 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 Cotswold 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 Cotswold 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 Cotswold District Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Cotswold District Council granted 92% of its householder applications in the year to 31 March 2026, and Adlestrop Conservation Area 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 Adlestrop, Bledington and Broadwell, 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 (40% of 1,720 homes), a side-return infill frequently pairs with it to square off the plan; on wider early postwar houses (8%), a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The 1,720 homes here are 40% pre-1900, 9% 1983-1992, 8% 1945-1954, 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 Cotswold 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 Fosseridge projects come up most often:

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