Planning and approvals in Whitehaven
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).

Your questions about an orangery extension in Whitehaven
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Whitehaven, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Whitehaven?
Yes. We cover Whitehaven and the surrounding parts of Cumbria. Site visits are free and there is no obligation.
Do I need building regulations approval in Whitehaven?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
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.
