Extensions in and around Peterlee
Site visits are available across Peterlee (SR8). Nearby, we also take on projects in Seaham (5 miles), Hartlepool (7 miles), Durham (10 miles), Chester-le-Street (12 miles).
Houghton-le-Spring, in Tyne and Wear, is roughly 8 miles from Peterlee and also on our list. Across the North East, houses often have rear yards or modest gardens, so compact, well-lit single-storey extensions make the biggest difference.
What we take care of
- Foundations, walls and insulated perimeter roof
- Design of piers, roof perimeter and lantern proportions
- Aluminium or timber lantern and full-height glazing
- Heating sized for the glass area
- Opening into the main house
Planning and approvals in Peterlee
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).
What should I budget for an orangery extension in Peterlee?

Questions people ask about orangery extensions
How long does an orangery extension take to build in Peterlee?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Will my neighbours in Peterlee 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.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Peterlee, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
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.
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.
