Orangery and conservatory drawings for Cleeve St Michael's homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to Tewkesbury Borough Council's guidance and revised free until your decision.
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.

The difference is not marketing. A conservatory is predominantly glazed — at least three quarters of the roof and half of the walls — which is what earns it the building-regulations exemption. An orangery has a solid masonry perimeter with a glazed lantern set into a flat roof, so it usually reads as a conventional extension for building control and has to meet Part L thermal standards, Part A structure and Part B fire like any other room.
Both are judged the same way for planning: as rear extensions, against the Class A depth, height and eaves limits, and against Tewkesbury Borough Council's development plan and the design policies it applies to householder applications. Cleeve St Michael's is largely late-1950s and early-1960s houses (22% of 2,360 homes), early postwar houses (15%) and 2000s houses and apartments (7%), and the design question is usually whether the glazing reads as a lightweight addition to that stock or as a bolted-on conservatory kit. On period houses, an orangery with a properly proportioned lantern almost always sits better than a full-height glazed box.
In conservation areas such as Bishop's Cleeve Conservation Area, rear glazing is assessed on visibility from the street and on the effect on the rear elevation's character. 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.
Many conservatories are permitted development. You will need an application to Tewkesbury Borough Council where any of these apply:
We check the scheme against the Class A planning limits and against the building-regulations exemption at the same time, so you know before committing whether you are building an exempt conservatory or a fully regulated room.
Below is Tewkesbury Borough Council's real householder decision record, drawn from official planning statistics and refreshed 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. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Bishop's Cleeve and Bishop's Cleeve, the schemes that succeed keep the eaves below the neighbour's ground-floor cill line, set the glazing back from the boundary, and use a solid parapet or brick perimeter to tie the addition into the house. On late-1950s and early-1960s houses (22% of 2,360 homes), a lantern set in a flat roof usually reads better than a pitched glazed roof, and it avoids the summer overheating that makes full conservatories unusable for months a year.
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. The decision worth making early is whether to keep the separating doors. Keeping them preserves the building-regulations exemption but leaves you with a room that is not part of the house; removing them creates one continuous space but brings the whole addition inside Part L, which changes the glazing specification and usually the heating design too. We set out both versions before you commit.
We draw glazed rear additions across Cleeve St Michael's. A few of the areas where they come up most often:

The planning test is the same for both. The building-regulations test is not.
| Structure | Planning route | Building regulations | Practical effect |
|---|---|---|---|
| Conservatory under 30m², doors retained | Class A rear extension limits | Largely exempt | Cheaper build, unheated in winter |
| Conservatory, doors removed | Class A rear extension limits | Part L applies in full | Continuous space, higher spec glazing |
| Orangery with solid perimeter and lantern | Class A rear extension limits | Fully regulated | Usable year round, better on period houses |
| Any of the above beyond the depth limits | Full householder application | As above | 8-week determination |
| Any of the above on designated land | Full householder application | As above | Design and visibility assessed |
Planning limits from the GPDO 2015, Schedule 2, Part 1, Class A; exemption criteria from the Building Regulations 2010, Schedule 2, Class 7.
A fixed process covering both consents, because they pull in different directions.
Send us your Cleeve St Michael's postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live Tewkesbury Borough Council decisions.
We measure the rear elevation, eaves and ground levels, and the neighbouring boundary — the numbers that decide both the projection limit and the 2-metre eaves rule.
Chartered designers develop the orangery or conservatory to your brief, and we set out clearly whether it stays inside the building-regulations exemption or becomes a fully regulated room.
We submit the certificate or application, manage validation and officer queries, and revise free until Tewkesbury Borough Council decides.
Often not. A conservatory is treated as a rear extension, so it can be permitted development within the Class A limits — 3 metres of projection on a terrace or semi, 4 metres on a detached house, with eaves under 3 metres where it sits within 2 metres of a boundary. In Cleeve St Michael's you will need an application to Tewkesbury Borough Council beyond those limits, and on designated land such as Bishop's Cleeve Conservation Area.
A conservatory is largely exempt if it is under 30 square metres, at ground level, separated from the house by external-quality doors, and has at least 75% of its roof and 50% of its walls glazed. Glazing, electrics and any drainage work still have to comply. Remove the separating doors and the exemption falls away — the space becomes part of the house and Part L thermal standards apply. This applies to your Cleeve St Michael's address specifically. Tewkesbury Borough Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by Tewkesbury Borough Council. The difference is in building control: an orangery's solid perimeter and flat roof with a lantern usually means it fails the glazing test for exemption, so it is fully regulated. That is why an orangery costs more to build but is comfortable in January. This applies to your Cleeve St Michael's address specifically.
Usually yes at the rear, though permitted-development rights are narrower on designated land and an Article 4 direction can remove them entirely. The assessment turns on whether the addition is visible from the street and how it meets the original rear elevation. A restrained orangery in matching brick with a lantern is consistently easier to get through than a proprietary glazed conservatory. This applies to your Cleeve St Michael's address specifically. Tewkesbury Borough Council is the decision-maker.
A fully glazed roof will, unless it is specified for it. That is the practical reason most of our clients end up building an orangery instead: a solid insulated roof perimeter with a lantern gives daylight without the greenhouse effect, and keeps the space usable across the year. We raise it at design stage because it is much cheaper to solve on paper than after the build. This applies to your Cleeve St Michael's address specifically. Tewkesbury Borough Council is the decision-maker.
If you excavate foundations within 3 metres of a neighbouring structure and deeper than its foundations, or build on the boundary itself, the Party Wall etc. Act 1996 applies and notice must be served. That is separate from Tewkesbury Borough Council's planning decision. We flag it at design stage so the notice period does not delay the start on site. This applies to your Cleeve St Michael's address specifically.
