Planning and approvals in Cromer
In England a glazed or orangery-style extension follows the same size limits as any single-storey rear extension: 3 m or 4 m without an application, or up to 6 m and 8 m through prior approval. Building regulations limit glazing to about a quarter of the new floor area plus the openings it replaces, unless whole-house calculations show the design still performs.
The planning position for a specific Cromer address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).

Is an orangery extension right for your house?
- Period and detached houses with a garden view
- Those who want daylight without overheating
- Homeowners replacing an older conservatory
The lantern-to-roof ratio sets the character. A wider solid perimeter gives a calmer, more room-like space and hides downlights and speakers; a bigger lantern feels brighter but needs more care against summer heat.
Local to Cromer
Across NR27, we can visit, measure and advise. We also work in nearby North Walsham (8 miles), Norwich (21 miles), Dereham (23 miles), Wymondham (26 miles).
Lowestoft, in Suffolk, is roughly 36 miles from Cromer and also on our list. The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.
Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
The price is fixed in writing once the design is settled, with a clear programme and payment stages.
Build and sign-off
Work is carried out to the agreed programme, inspected by building control and signed off at the end.
Orangery extension questions answered
Do I need building regulations approval in Cromer?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does an orangery extension take to build in Cromer?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do you cover all of Cromer?
Yes. We cover Cromer and the surrounding parts of Norfolk. Site visits are free and there is no obligation.
Will an orangery be too hot in summer?
Not if it is designed with solar-control glass, a solid perimeter and ventilation. We size the lantern and opening vents with that in mind.
Does an orangery need planning permission?
It follows the same size limits as other single-storey extensions. In England many fit within permitted development or prior approval; others need an application.
