Rear dormer drawings for Moreton East roofs — the box across the back slope that turns a low attic into a full-height room, drawn to Cotswold District Council's guidance and the volume limits, delivered in days and revised free until your decision, with a free approval-odds check first.
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 East contains the Todenham Conservation Area conservation area (Todenham 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), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Moreton East carries at least one Article 4 direction, and conservation areas including Todenham Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Moreton East is determined against an 8-week statutory target.
Todenham (conservation area designated in 1981), Moreton-in-Marsh (civil parish within Moreton East) and Todenham (civil parish within Moreton East) — these are the Moreton East pockets our drawings cover most. Heritage designations here include Todenham 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 810 homes here are 6% 1945-1954, 4% pre-1900, 4% 1919-1929, which is what sets the realistic roof and rear-projection options. On roofs the borough is simple gabled and hipped roofs typical of early postwar building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, over early postwar houses (6% of 810 homes), Victorian and earlier houses (4%) and early interwar houses (4%).
Moreton East's designated heritage is specific, and it is the first thing we check against your address: Todenham (conservation area designated in 1981). 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 East takes in Moreton-in-Marsh and Todenham. 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 East.
On stock, Moreton East is early postwar houses (6% of 810 homes), Victorian and earlier houses (4%) and early interwar houses (4%) — which is why simple gabled and hipped roofs typical of early postwar building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 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. Those are the numbers our drawings are prepared against.
The full build-period split for Moreton East runs pre-1900 4% (30 homes), 1919-1929 4% (30 homes), 1945-1954 6% (50 homes) and 1965-1972 1% (10 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 East 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 box dormer is the workhorse loft, and most of Moreton East is built for it — the borough runs to early postwar houses (6% of 810 homes), Victorian and earlier houses (4%) and early interwar houses (4%) under simple gabled and hipped roofs typical of early postwar building and steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building, and a flat-roofed box across the rear slope is the cheapest cubic metre of full-height space those roofs give up. Cotswold District Council tests the dormer against the adopted Cotswold local plan and Cotswold District Council's design guidance for householder work, and because permitted development turns on a number, the volume you propose against the volume you have left is the first thing an officer or a certificate checks.
That is why the arithmetic goes on the drawings. We calculate the box against the 40- or 50-cubic-metre allowance, count any earlier roof enlargement into the total, hold the flat roof below the ridge and set the face back off the eaves so the dormer reads as subordinate. Moreton East contains the Todenham Conservation Area conservation area (Todenham Conservation Area designated 1981), so materials, fenestration and roof form are assessed against the appraisal, so the cheeks, the window line and the material are drawn to answer it rather than invite a query.
Where Moreton East's streets are protected — Todenham Conservation Area among them — the Class B dormer right is switched off and even a modest rear box needs consent. 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 East. We confirm the designation before the box is sized.
Many rear dormers in Moreton East are permitted development, but the volume and position decide it. You will normally need a full application to Cotswold District Council if any of these apply:
We draw the box within its volume allowance, the flat roof below the ridge and the face set back off the eaves — the three things a dormer stands or falls on — and submit a validation-complete pack, whether that is a lawful development certificate 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 Todenham Conservation Area shapes what is approved here. A dormer is decided on volume and set-back, so a pack that shows the calculation and the eaves detail is cleared faster and refused less often than a DIY submission.

Across Todenham, Moreton-in-Marsh and Todenham, the dormer that goes through is the subordinate rear box: flat roof kept low, cheeks clad to recede, side windows obscure-glazed against overlooking, and the whole thing set back so the original eaves line still reads from the garden. On simple gabled and hipped roofs typical of early postwar building, this returns a full-height double and en-suite from what was standing-room-only, usually inside the permitted-development volume.
The 810 homes here are 6% 1945-1954, 4% pre-1900, 4% 1919-1929, which is what sets the realistic roof and rear-projection options. We keep the box off the ridge, match the cheek material to the roof, and where the volume is already spent — or the street is designated — draw the dormer as a householder application composed to Cotswold District Council's roof-alteration guidance rather than push a certificate that would be refused.
We draw rear dormers on the terraced and semi-detached streets across the borough. A few of the neighbourhoods where Moreton East dormers come up most often:

Whether a dormer in Moreton East needs permission comes down to where it sits and how big the box is. This is how the cases compare.
| Dormer type | Permitted development? | What it gains | What Cotswold District Council checks |
|---|---|---|---|
| Rear box, within volume | Usually yes | Full-height room across the back | Volume total, 20cm eaves set-back |
| Rear box, over volume limit | No — full application | A larger room | How far over the allowance, bulk |
| Front or side dormer | No — full application | Light to the front rooms | Visibility from the street, character |
| Dormer in a conservation area | No — full application | Same space, extra scrutiny | Roof form and street appearance |
In conservation areas such as Todenham Conservation Area, Class B dormer rights are removed and every dormer needs a full application.
A fixed process built around how Cotswold District Council validates and decides dormer applications — most drawings are submission-ready within seven days of survey.
Send us your Moreton East postcode and roof type. We confirm your conservation and Article 4 status, work out how much permitted-development volume you have left, and score your odds against live Cotswold District Council decisions.
We measure ridge and eaves heights, roof pitch and the existing loft floor — the numbers the volume calculation, the set-back and the head heights depend on.
Chartered designers develop the box to your brief, drawn inside the Class B volume limits or, where those are exhausted or removed, to Cotswold District Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Cotswold District Council issues its decision.
Often not. A rear box dormer within 40 cubic metres on a terrace, or 50 on a semi or detached house, set back at least 20 centimetres from the eaves and kept below the ridge, is usually permitted development. In Moreton East you will need a full application to Cotswold District Council for a front or side dormer, a box that exceeds the volume, and any dormer in a conservation area such as Todenham Conservation Area, where those rights are removed.
The permitted-development limit is a volume, not a footprint: 40 cubic metres of added roof space on a terraced house and 50 on a semi-detached or detached one, and any earlier loft enlargement counts against that total. In Moreton East the box must also sit below the ridge and back from the eaves. We measure your roof and calculate the exact volume you have left before drawing. Cotswold District Council is the decision-maker.
Not under permitted development. A dormer on the front roof slope, or one facing a highway, always needs a full application to Cotswold District Council, because it changes how the house reads from the street. Rear box dormers are far more likely to be approved — or to be permitted development outright — which is why almost every Moreton East dormer we draw sits on the back slope.
Often, on a terrace or semi. If the dormer or the loft steelwork meets the party wall with your neighbour, the Party Wall etc. Act applies and notice must be served before work starts — separately from Cotswold District Council's planning decision. We flag the party-wall junction on the drawings so a surveyor can be appointed early and the build is not held up. This applies to your Moreton East address specifically.
If your dormer is permitted development, a lawful development certificate from Cotswold District Council is council-stamped proof of it — worth holding, because a buyer's solicitor will ask for it when you sell. We prepare and submit the certificate with the same measured drawing pack that shows the box within its volume allowance. This applies to your Moreton East address specifically.
We price each Moreton East dormer individually, because the roof pitch and the volume left vary house to house, and send a fixed, no-obligation quote within one working day. It covers the full drawing pack with free revisions until Cotswold District Council approves, and we confirm at the outset whether your box is permitted development or needs an application.
