The fast route to a deep single-storey rear extension in Moreton West — up to 6 metres on an attached house or 8 on a detached one — via Cotswold District Council's prior approval scheme rather than a full planning application.
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. Moreton West contains Batsford Conservation Area, Bourton On The Hill Conservation Area, Moreton-In-Marsh Conservation Area conservation areas (Batsford Conservation Area designated 1990), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Cotswold District Council needs a full application. Moreton West carries at least one Article 4 direction, and conservation areas including Batsford Conservation Area, Bourton On The Hill Conservation Area and Moreton-In-Marsh Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Moreton West is determined against an 8-week statutory target.
Batsford (conservation area designated in 1990), Bourton On The Hill (conservation area designated in 1972), Moreton-In-Marsh (conservation area designated in 2065), Moreton-in-Marsh (civil parish within Moreton West), Batsford (civil parish within Moreton West) and Bourton-on-the-Hill (civil parish within Moreton West) — these are the Moreton West pockets our drawings cover most. Heritage designations here include Batsford Conservation Area, Bourton On The Hill Conservation Area and Moreton-In-Marsh Conservation Area. Cotswold District Council weighs each proposal against Cotswold District Council's development plan and the design policies it applies to householder applications, where the 1,910 homes here are 16% 1983-1992, 14% 2000-2008, 12% 1965-1972, which is what sets the realistic roof and rear-projection options. On roofs the borough is trussed-rafter roofs typical of 1980s building and trussed-rafter roofs typical of 2000s building, over 1980s estate houses (16% of 1,910 homes), 2000s houses and apartments (14%) and late-1960s and early-1970s houses (12%).
Heritage designation is the single biggest variable in Moreton West, and it is address-specific: Batsford (conservation area designated in 1990), Bourton On The Hill (conservation area designated in 1972) and Moreton-In-Marsh (conservation area designated in 2065). 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, Moreton West takes in Moreton-in-Marsh, Batsford and Bourton-on-the-Hill. 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 Moreton West.
On stock, Moreton West is 1980s estate houses (16% of 1,910 homes), 2000s houses and apartments (14%) and late-1960s and early-1970s houses (12%) — which is why trussed-rafter roofs typical of 1980s building and trussed-rafter roofs typical of 2000s 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 work from the council's own published record.
The full build-period split for Moreton West runs pre-1900 9% (180 homes), 1900-1918 1% (10 homes), 1930-1939 7% (130 homes), 1945-1954 2% (40 homes), 1955-1964 5% (100 homes), 1965-1972 12% (220 homes), 1973-1982 8% (150 homes), 1983-1992 16% (310 homes), 1993-1999 9% (180 homes) and 2000-2008 14% (260 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, Fosseridge and Kemble, so a decision in Moreton West 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.

The ordinary Class A limits stop a single-storey rear extension at 3 metres on an attached house and 4 on a detached one. The larger home extension scheme doubles both, on condition that the council is told first. That notification is not an application for permission — the council cannot refuse on design, materials or policy grounds. It can only consider the effect on the amenity of adjoining premises, and only if a neighbour actually objects during the 21-day consultation.
The other conditions still apply and are strict: single storey only, no higher than 4 metres, eaves no higher than the existing eaves, and no more than half the land around the original house covered. It is not available on designated land, so a house in a conservation area such as Batsford Conservation Area and Bourton On The Hill Conservation Area cannot use it at all. Materials must be similar to the existing house, and the extension must not include a veranda, balcony or raised platform.
Moreton West is largely 1980s estate houses (16% of 1,910 homes), 2000s houses and apartments (14%) and late-1960s and early-1970s houses (12%). Moreton West contains Batsford Conservation Area, Bourton On The Hill Conservation Area, Moreton-In-Marsh Conservation Area conservation areas (Batsford Conservation Area designated 1990), so materials, fenestration and roof form are assessed against the appraisal, which matters here because an objecting neighbour puts amenity squarely in front of a case officer. 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 Moreton West.
The scheme is available where all of these hold. Fail any one and it is a full application to Cotswold District Council instead:
We prepare the notification pack Cotswold District Council needs — plans, elevations, a site plan with the adjoining owners identified — and manage the 21-day neighbour consultation so the 42-day clock is not restarted by an incomplete submission.
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 Batsford Conservation Area shapes what is approved here. Prior approval turns on neighbour amenity alone, so the drawings that matter are the ones showing the relationship to the boundary.

Across Batsford, Bourton On The Hill and Moreton-In-Marsh, the notifications that clear without objection are the ones that treat the neighbour as the audience. We show the extension in section against the boundary, demonstrate the 45-degree daylight relationship to the nearest habitable window, and where the plot is tight we taper the depth away from the boundary rather than running the full 6 metres to the fence.
The 1,910 homes here are 16% 1983-1992, 14% 2000-2008, 12% 1965-1972, which is what sets the realistic roof and rear-projection options. Where an objection does arrive, the council's assessment is narrow: loss of light, outlook and overbearing effect on the adjoining property, nothing else. A pack that has already answered those three points on the drawings usually survives an objection, whereas one that leaves them to the officer's imagination usually does not.
We prepare prior-approval notifications across Moreton West. A few of the areas where deep rear extensions come up most often:

Same extension, two routes, very different tests.
| Route | Depth allowed | What the council may consider | Timescale |
|---|---|---|---|
| Ordinary Class A permitted development | 3m attached / 4m detached | Nothing — no application needed | Immediate |
| Larger home extension prior approval | 6m attached / 8m detached | Amenity of adjoining premises, only if a neighbour objects | 21-day consultation, 42-day determination |
| Full householder application | No fixed limit | Design, materials, policy, amenity, everything | 8-week target |
| Any of these on designated land | 3m / 4m only | Prior approval scheme unavailable | Full application beyond the limits |
Limits and procedure from the GPDO 2015, Schedule 2, Part 1, Class A and paragraph A.4, made permanent by amendment in 2019.
A process built around the 21-day consultation, which is where these schemes are won or lost.
Send us your Moreton West postcode and house type. We confirm whether the property is on designated land, whether the scheme is available, and what depth you can realistically take.
We measure the original rear wall, eaves height, boundary distances and the neighbouring windows that the amenity assessment will turn on.
We draw the extension to the 6m or 8m limit with the boundary relationship shown in section, and prepare the written description and adjoining-owner details Cotswold District Council needs to start the consultation.
We submit, track the 21-day consultation and the 42-day determination, respond to any objection on amenity grounds, and revise free until the decision.
Three metres on a terraced or semi-detached house and four on a detached one under ordinary permitted development. Under the larger home extension prior approval scheme those double to six and eight metres, provided you notify Cotswold District Council before starting and the conditions on height, materials and land coverage are met. The scheme is not available on designated land. This applies to your Moreton West address specifically.
It is a notification, not an application for permission. You tell Cotswold District Council what you intend to build, it writes to the adjoining owners, and they have 21 days to object. If nobody objects, you may build. If someone does, the council assesses the effect on the amenity of adjoining premises and must decide within 42 days. Design and policy are not in scope. This applies to your Moreton West address specifically.
The council then considers the impact on the amenity of the adjoining property — loss of light, loss of outlook, and overbearing effect — and nothing else. It cannot refuse because it dislikes the design or the materials. We prepare the drawings so those three questions are already answered in section and on the site plan, which is what usually carries an objected scheme through. This applies to your Moreton West address specifically. Cotswold District Council is the decision-maker.
No. The larger home extension scheme is unavailable on designated land, which includes conservation areas such as Batsford Conservation Area and Bourton On The Hill Conservation Area, national landscapes, national parks and world heritage sites. On those properties the ordinary 3-metre and 4-metre limits apply, and anything deeper needs a full householder application to Cotswold District Council. This applies to your Moreton West address specifically.
Twenty-one days for the neighbour consultation, and a maximum of 42 days from a valid submission for the council to determine it. If the council does not respond within 42 days you may proceed as notified. That deadline is the scheme's real advantage over a full application, and it is why validation completeness matters so much. This applies to your Moreton West address specifically. Cotswold District Council is the decision-maker.
Yes — always. Prior approval deals only with the planning position. A 6-metre rear extension still needs building control approval for foundations, structure, drainage, thermal performance and fire safety, and the beam over the opening into the existing house needs designing and calculating. We prepare both sets so the notified scheme is the buildable one. This applies to your Moreton West address specifically. Cotswold District Council is the decision-maker.
We quote each Moreton West scheme individually, because plot shape and the boundary relationship drive the work, and send a fixed, no-obligation quote within one working day.
