Annexe and granny-flat drawings for Moreton West homes — designed to stay ancillary to the main house rather than become a separate dwelling, drawn to Cotswold District Council's policies, delivered in days and revised free until your decision.
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.

Councils do not decide annexes on square metres. They decide whether, once built, the accommodation forms part of one planning unit with the main house or a second one beside it. Cotswold District Council looks at whether the garden is shared or divided, whether the annexe has its own street access and address, whether the occupier could live there entirely independently, and whether the two households would function as one. That is the whole case, and it is made or lost on the layout.
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%), which shapes the realistic options: converting part of the existing house, extending it, or building a detached unit in the garden. A detached annexe can sometimes sit under Class E as an outbuilding incidental to the enjoyment of the dwellinghouse — but sleeping accommodation is generally not "incidental", so a garden annexe with a bedroom usually needs its own permission rather than relying on outbuilding rights.
In Moreton West's conservation areas — including Batsford Conservation Area and Bourton On The Hill Conservation Area — a garden building is also judged on its effect on the character of the area, which limits height and footprint before the use question is reached. 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.
An annexe almost always needs an application to Cotswold District Council. Expect one where any of these apply:
We plan the annexe so its relationship to the main house is visible on the page — shared garden, connected access, a layout that reads as one household — and set out the case Cotswold District Council has to test, rather than leaving the officer to assume the worst.
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. Annexe applications are decided on use as much as design, so the supporting case matters as much as the elevations.

Across Batsford, Bourton On The Hill and Moreton-In-Marsh, the annexes that succeed keep one shared garden, take access past the main house rather than from the street, and are modest against the host building — single storey where the plot is overlooked, and set back from boundaries. On 1980s estate houses (16% of 1,910 homes), converting an integral garage or a rear ground floor is often approved more readily than a detached garden unit, because the ancillary relationship is self-evident.
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. Where Cotswold District Council grants permission, it commonly attaches a condition tying occupation of the annexe to the main dwelling. That condition is not a problem to be avoided — it is usually the mechanism that makes approval possible, and we draft the application on that basis rather than pretending the annexe is something it is not.
We draw annexes across Moreton West. A few of the areas where multigenerational schemes come up most often:

Three similar buildings, three different consents. This is what separates them.
| What you build | Planning status | Key test | What Cotswold District Council checks |
|---|---|---|---|
| Garden room, no sleeping space | Often Class E permitted development | Incidental to the house | Height, footprint, boundary position |
| Annexe used by the household | Full application, usually with a tie condition | Ancillary use | Shared garden and access, layout |
| Self-contained unit, own access | New dwelling — full application | Separate planning unit | Policy on new homes, amenity, parking |
| Converted garage or ground floor | Often permitted, use still assessed | Whether use changes | Independence of the accommodation |
| Annexe on designated land | Full application | Designation | Character and appearance |
The ancillary/separate-dwelling distinction comes from section 55 of the Town and Country Planning Act 1990; outbuilding limits from the GPDO 2015, Schedule 2, Part 1, Class E.
A fixed process built around how Cotswold District Council tests the use question as well as the design.
Tell us who the annexe is for and where it would sit on the plot. We confirm designation status and tell you honestly whether the scheme reads as ancillary or as a separate dwelling in Moreton West.
We measure the plot, the existing house and the access route, so the shared-garden and shared-access case can be drawn rather than asserted.
Chartered designers develop the annexe to your brief, with the layout, access and garden relationship arranged to support the ancillary case under Cotswold District Council's policies.
We submit the application with a supporting statement on use, manage validation and case-officer queries, and revise free until Cotswold District Council decides.
Almost always. Sleeping accommodation is generally not "incidental" to the enjoyment of a house, so it falls outside the outbuilding permitted-development right, and any annexe that could function independently raises a change-of-use question under section 55. In Moreton West we prepare a full application to Cotswold District Council and make the ancillary case explicitly rather than hoping it is not asked.
A shared garden rather than a divided one, access through the main property rather than a separate street entrance, occupation by a member of the same household, and a physical and functional relationship with the main house. Cotswold District Council weighs those together — no single feature decides it, but a separate front door and a fenced-off garden together usually settle it against you. This applies to your Moreton West address specifically.
Yes, subject to permission. A detached garden annexe is assessed on its scale against the plot, its effect on neighbours and the character of the area, and then on the use question. Keeping it single storey, set in from boundaries and served off the shared garden gives it the best prospect in Moreton West, particularly near designated areas such as Batsford Conservation Area and Bourton On The Hill Conservation Area. Cotswold District Council is the decision-maker.
Commonly, yes — a condition tying occupation of the annexe to the main dwelling, so it cannot be sold or let separately. That is normally what makes approval possible, because it removes the concern that a new independent home is being created without going through housing policy. The condition runs with the land, so it matters at resale, and we explain the implications before you commit. This applies to your Moreton West address specifically. Cotswold District Council is the decision-maker.
Yes. A new annexe is new habitable accommodation, so structure, fire escape, insulation and ventilation all apply, and a detached annexe close to a boundary raises fire-spread requirements as well. Planning and building control are separate consents with separate submissions — we prepare both so the approved design is the one that can actually be built. This applies to your Moreton West address specifically. Cotswold District Council is the decision-maker.
A householder application runs to an eight-week statutory target; where the council treats the annexe as creating a new unit it becomes a minor application with a thirteen-week target instead. Which route applies depends on how the use is characterised, which is precisely why the ancillary case is worth making properly at the outset. This applies to your Moreton West address specifically. Cotswold District Council is the decision-maker.
