Orangery and conservatory drawings for Tettenhall homes — checked against the Class A rear limits and the 30m² building-regulations exemption, drawn to City of Wolverhampton Council's guidance and revised free until your decision.
City of Wolverhampton Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The western edge of Tettenhall sits in green belt around Wergs and the Smestow Valley, where extensions face the openness test rather than ordinary householder policy, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910) and interwar (1918–1939) 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. Tettenhall carries at least one Article 4 direction, and conservation areas including Tettenhall Greens, Tettenhall Wood and Tettenhall Road remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Tettenhall is determined against an 8-week statutory target.
Upper Green (the historic village core around the church and the Upper Green), Lower Green (cottages and villas framing the Lower Green conservation area), Tettenhall Wood (a leafy hilltop of large detached houses and older cottages), Compton (villas along the Bridgnorth Road beside the Staffs & Worcs Canal), Aldersley (interwar semis edging the green belt and Smestow Valley) and Wergs (large detached homes on the rural western fringe) — these are the Tettenhall pockets our drawings cover most. Heritage designations here include Tettenhall Greens, Tettenhall Wood, Tettenhall Road and The Woodlands. City of Wolverhampton Council weighs each proposal against the Black Country Plan / Wolverhampton Local Plan and the City Centre AAP, where the Black Country's industrial-heritage policies protect canal-side character along the Staffordshire and Worcestershire Canal at Compton. On roofs the borough is gabled and half-timbered roofs on the Arts-and-Crafts villas and hipped roofs on the interwar detached houses, over grand Victorian and Edwardian villas on leafy plots, interwar detached and semi-detached houses and older village cottages around the Upper and Lower Greens.
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 the Black Country Plan / Wolverhampton Local Plan and the City Centre AAP. Tettenhall is largely grand Victorian and Edwardian villas on leafy plots, interwar detached and semi-detached houses and older village cottages around the Upper and Lower Greens, 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 Tettenhall Greens and Tettenhall Wood, rear glazing is assessed on visibility from the street and on the effect on the rear elevation's character. Tettenhall is one of Wolverhampton's most heavily protected quarters, with the Tettenhall Greens, Tettenhall Wood and Tettenhall Road conservation areas layered on top of the city-wide small-HMO Article 4 direction that has required planning consent for 3–6 person HMOs across the whole city since 14 September 2017.
Many conservatories are permitted development. You will need an application to City of Wolverhampton 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 City of Wolverhampton Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Wolverhampton grants a healthy share of householder applications, and in Tettenhall conservation-area character and green-belt openness on the western fringe are the recurring pinch points. Glazed rear additions are judged on depth, eaves height and how the glazing meets the existing elevation.

Across Upper Green, Lower Green and Tettenhall Wood, 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 grand victorian and edwardian villas on leafy plots, 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.
The western edge of Tettenhall sits in green belt around Wergs and the Smestow Valley, where extensions face the openness test rather than ordinary householder policy. 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 Tettenhall. A few of the areas where they come up most often:
Orangery and conservatory drawings for Upper Green — the historic village core around the church and the Upper Green — checked against the Class A limits and drawn to City of Wolverhampton Council's guidance.
Orangery and conservatory drawings for Lower Green — cottages and villas framing the Lower Green conservation area — checked against the Class A limits and drawn to City of Wolverhampton Council's guidance.
Orangery and conservatory drawings for Tettenhall Wood — a leafy hilltop of large detached houses and older cottages — checked against the Class A limits and drawn to City of Wolverhampton Council's guidance.
Orangery and conservatory drawings for Compton — villas along the Bridgnorth Road beside the Staffs & Worcs Canal — checked against the Class A limits and drawn to City of Wolverhampton Council's guidance.
Orangery and conservatory drawings for Aldersley — interwar semis edging the green belt and Smestow Valley — checked against the Class A limits and drawn to City of Wolverhampton Council's guidance.

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 Tettenhall postcode and house type. We confirm the Class A limits that apply, check designation status, and score your odds against live City of Wolverhampton 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 City of Wolverhampton 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 Tettenhall you will need an application to City of Wolverhampton Council beyond those limits, and on designated land such as Tettenhall Greens and Tettenhall Wood.
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 Tettenhall address specifically. City of Wolverhampton Council is the decision-maker.
For planning, none — both are rear extensions assessed against the same Class A limits by City of Wolverhampton 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 Tettenhall 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 Tettenhall address specifically. City of Wolverhampton 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 Tettenhall address specifically. City of Wolverhampton 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 City of Wolverhampton 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 Tettenhall address specifically.
