Dormer, hip-to-gable and mansard loft conversion drawings for Cleeve St Michael's homes — prepared to Tewkesbury Borough Council's design guidance, delivered in days and revised free until your decision lands, with a free approval-odds score first.
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. Cleeve St Michael's contains the Bishop's Cleeve Conservation Area conservation area (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 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. Cleeve St Michael's carries at least one Article 4 direction, and conservation areas including Bishop's Cleeve Conservation Area remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Cleeve St Michael's is determined against an 8-week statutory target.
Bishop's Cleeve (conservation area designated in 1979) and Bishop's Cleeve (civil parish within Cleeve St Michael's) — these are the Cleeve St Michael's pockets our drawings cover most. Heritage designations here include Bishop's Cleeve Conservation Area. Tewkesbury Borough Council weighs each proposal against Tewkesbury Borough Council's development plan and the design policies it applies to householder applications, where the 2,360 homes here are 22% 1955-1964, 15% 1945-1954, 7% 2000-2008, which is what sets the realistic roof and rear-projection options. On roofs the borough is shallow gabled roofs typical of that period's building and simple gabled and hipped roofs typical of early postwar building, over late-1950s and early-1960s houses (22% of 2,360 homes), early postwar houses (15%) and 2000s houses and apartments (7%).
What is permitted in Cleeve St Michael's turns on designation first, so that is where we start: Bishop's Cleeve (conservation area designated in 1979). 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, Cleeve St Michael's takes in Bishop's Cleeve. 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 Cleeve St Michael's.
On stock, Cleeve St Michael's is late-1950s and early-1960s houses (22% of 2,360 homes), early postwar houses (15%) and 2000s houses and apartments (7%) — which is why shallow gabled roofs typical of that period's building and simple gabled and hipped roofs typical of early postwar 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. We draw to that record rather than to a national average.
The full build-period split for Cleeve St Michael's runs pre-1900 2% (40 homes), 1930-1939 1% (30 homes), 1945-1954 15% (350 homes), 1955-1964 22% (510 homes), 1965-1972 2% (40 homes), 1973-1982 3% (70 homes), 1983-1992 1% (30 homes), 1993-1999 2% (40 homes) and 2000-2008 7% (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 Tewkesbury South, Winchcombe, Cleeve Hill and Isbourne, so a decision in Cleeve St Michael's 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.

Cleeve St Michael's's roofs set the brief. The borough is built largely from late-1950s and early-1960s houses (22% of 2,360 homes), early postwar houses (15%) and 2000s houses and apartments (7%), and its lofts sit under shallow gabled roofs typical of that period's building and simple gabled and hipped roofs typical of early postwar building — the geometry that decides whether a rear dormer, a hip-to-gable or a mansard gives you the headroom you want. Tewkesbury Borough Council assesses loft proposals against Tewkesbury Borough Council's development plan and the design policies it applies to householder applications, and its case officers read each roof against the pair next door and the wider street before they read the plans.
That makes drawing quality decisive. We measure ridge and eaves heights, roof pitch and the existing stair, calculate the added volume against the permitted-development limits exactly, and show the workings on the drawings so Tewkesbury Borough Council can verify them. Cleeve St Michael's contains the Bishop's Cleeve Conservation Area conservation area (Bishop's Cleeve Conservation Area designated 1979), so materials, fenestration and roof form are assessed against the appraisal, so we resolve it on the page rather than leave it for the case officer to raise.
Cleeve St Michael's also carries protected streets — Bishop's Cleeve 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 Cleeve St Michael's. We check your address against those designations before a line is drawn.
Many Cleeve St Michael's loft conversions proceed without planning permission — a rear dormer within the permitted-development volume limits (40 cubic metres on a terrace, 50 on a semi or detached house) is usually lawful. You will normally need a full application to Tewkesbury Borough Council if any of these apply:
We draw the roof line, the ridge height and the neighbour's daylight on the page — the relationships Tewkesbury Borough Council's officers check first — and submit a validation-complete pack, whether that is a lawful development certificate or a full householder application.
Below is Tewkesbury Borough Council's real householder decision record, pulled from official planning statistics and updated as new data lands. Tewkesbury Borough Council granted 93% of its householder applications in the year to 31 March 2026, and Bishop's Cleeve Conservation Area shapes what is approved here. Professionally prepared loft drawings anticipate those pressure points before submission, which is why complete, policy-literate packs are decided faster and refused less often than DIY applications.

Across Bishop's Cleeve and Bishop's Cleeve, the recurring loft is the rear dormer — a box across the back roof slope that turns a cramped attic into a full-height double bedroom and en-suite. On shallow gabled roofs typical of that period's building, that is usually the most efficient use of the roof; where the stock is simple gabled and hipped roofs typical of early postwar building, a hip-to-gable followed by a rear dormer unlocks far more space, though it needs a full application.
The 2,360 homes here are 22% 1955-1964, 15% 1945-1954, 7% 2000-2008, which is what sets the realistic roof and rear-projection options. We draw the dormer inside the volume allowance, keep the flat-roof build-up below the ridge, and set the face back from the eaves as the rules require — so the pack answers Tewkesbury Borough Council's questions before they are asked. Where permitted-development rights are exhausted or removed, we prepare a householder application composed to the borough's roof-alteration guidance instead.
We draw loft conversions on every street in the borough. A few of the neighbourhoods where Cleeve St Michael's roofs come up most often:

The right loft in Cleeve St Michael's depends on your roof. This is how the main types compare on planning route and the space they add.
| Loft type | Permitted development? | Space & headroom | What Tewkesbury Borough Council checks |
|---|---|---|---|
| Rear dormer | Usually yes, within volume limits | Full-height double room at the back | Volume, set-back from eaves, ridge height |
| Hip-to-gable | No — full application | Extends the whole side of the roof | Roof bulk and the symmetry of the pair |
| Mansard | No — full application | Maximum floor area across the roof | Street character, especially in conservation areas |
| Rooflights only | Usually yes (Class C) | Light and headroom, no extra footprint | Whether rooflights sit within the existing slope |
Route depends on your street — conservation areas such as Bishop's Cleeve Conservation Area and Article 4 directions can remove permitted-development rights.
A fixed process built around how Tewkesbury Borough Council validates and decides householder loft applications — most drawings are submission-ready within seven days of survey.
Tell us your Cleeve St Michael's postcode and roof type. We confirm your conservation and Article 4 status, how much permitted-development volume you have left, and score your odds against live Tewkesbury Borough Council decisions.
We measure ridge and eaves heights, roof pitch, joist levels and the existing stair — the numbers the volume calculation and head heights depend on.
Chartered designers develop the dormer, hip-to-gable or mansard to your brief, drawn inside the Class B limits or to Tewkesbury Borough Council's roof-alteration guidance.
We submit the certificate or application, manage validation and case-officer queries, and revise the drawings free until Tewkesbury Borough Council issues its decision.
Often not. A rear dormer within 40 cubic metres on a terrace, or 50 on a semi-detached or detached house, set back from the eaves and no higher than the ridge, is usually permitted development. In Cleeve St Michael's the main exceptions are hip-to-gable conversions, dormers visible from the highway, and homes in conservation areas such as Bishop's Cleeve Conservation Area or on streets with an Article 4 direction. Tewkesbury Borough Council is the decision-maker.
Generally no. In conservation areas including Bishop's Cleeve Conservation Area, Class B permitted-development rights for lofts are removed, so a rear dormer that would be lawful elsewhere needs a full application to Tewkesbury Borough Council. 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 Cleeve St Michael's. We check your exact address before drawing.
On shallow gabled roofs typical of that period's building, common across Cleeve St Michael's, a rear dormer is usually the most efficient conversion and often permitted development. Where the roof is simple gabled and hipped roofs typical of early postwar building, a hip-to-gable followed by a rear dormer gains far more usable space but needs planning permission. Our survey confirms which your roof supports before we draw. Tewkesbury Borough Council is the decision-maker.
A householder planning application in Cleeve St Michael's runs to a statutory eight-week target, and a lawful development certificate to eight weeks as well, though validation can add time if the pack is incomplete. We submit validation-complete drawings and manage case-officer queries to keep the decision on track. Tewkesbury Borough Council is the decision-maker.
If your dormer is permitted development, a lawful development certificate from Tewkesbury Borough Council is council-stamped proof of that — worth having, because every buyer's solicitor will ask for it when you sell. We prepare and submit the certificate application with the same drawing pack. This applies to your Cleeve St Michael's address specifically.
Every roof is different, so we quote each Cleeve St Michael's project individually — a fixed, no-obligation price back within one working day.
