Across EX31, EX32, we can visit, measure and advise. We also work in nearby Bideford (8 miles), Tiverton (28 miles), Exeter (34 miles), Newton Abbot (43 miles).
Just over the Cornwall border, Launceston is about 34 miles away. South West homes range from terraced streets in the cities to stone cottages and bungalows in the countryside, and conservation areas are common in historic centres.
Who an orangery extension suits
- Homeowners replacing an older conservatory
- Those who want daylight without overheating
- Period and detached houses with a garden view
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.
Do I need planning permission in Barnstaple?
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.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Common questions in Barnstaple
Who do I contract with for an orangery extension in Barnstaple?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do you cover all of Barnstaple?
Yes. We cover Barnstaple and the surrounding parts of Devon. Site visits are free and there is no obligation.
Do I need building regulations approval in Barnstaple?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
What is the difference between an orangery and a conservatory?
An orangery has a solid roof perimeter with a central lantern and more solid wall, so it is warmer and more like a room. A conservatory is mostly glass. Building regulations treat a heated orangery joined to the house as an extension.
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.
