Local to Corby
Postcode districts we cover around Corby include NN17, NN18. Nearby, we also take on projects in Kettering (7 miles), Market Harborough (10 miles), Wellingborough (13 miles), Rushden (15 miles).
Homes across the East Midlands often have usable side land or a driveway beside the house, which opens up side and wraparound options.
Do I need planning permission in Corby?
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.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
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).

Questions people ask about orangery extensions
Will my neighbours in Corby be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do you cover all of Corby?
Yes. We cover Corby and the surrounding parts of Northamptonshire. Site visits are free and there is no obligation.
How long does an orangery extension take to build in Corby?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
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.
How much does an orangery cost?
Our guide range is about £2,280 to £4,280 per m² including VAT, so a 16 m² standard-spec orangery is typically £42,500 to £53,500 in Corby.
