Extensions in and around Ashton-in-Makerfield
Across WN4, we can visit, measure and advise. Nearby, we also take on projects in Wigan (4 miles), Hindley (4 miles), Leigh (5 miles), Westhoughton (7 miles).
The North West has a high share of Victorian and Edwardian terraces with rear yards and outriggers, plus large areas of inter-war semis in the suburbs.
Planning rules that apply in Ashton-in-Makerfield
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 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.
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).
Included in a typical project
- Aluminium or timber lantern and full-height glazing
- Heating sized for the glass area
- Foundations, walls and insulated perimeter roof
- Thermal calculations where glazing is generous
- Opening into the main house

Common questions in Ashton-in-Makerfield
Who do I contract with for an orangery extension in Ashton-in-Makerfield?
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.
How long does an orangery extension take to build in Ashton-in-Makerfield?
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 Ashton-in-Makerfield 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.
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.
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 Ashton-in-Makerfield.
