Covering Atherton
We work in Atherton (M46) and the places around it, including Tyldesley, Westhoughton and Leigh.
Homes in the North West
Terraced housing is a defining feature of many North West towns, which brings party walls and narrow access into most projects, with more space to extend on suburban semis.
What does a garage conversion involve?
A garage conversion turns an attached, integral or detached garage into a habitable room by infilling the door opening, insulating the floor, walls and roof, and adding windows, heating and power. It is one of the quickest and cheapest ways to add a room.
- Garage door removal and brick infill with window
- Heating, electrics and data points
- Plastering, skirting and decoration-ready finish
What will a garage conversion cost?
Typical ranges for garage conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

| Single integral garage | £12,000 to £17,000 |
| Single attached garage | £12,000 to £24,000 |

Planning and building rules in Atherton
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
An internal garage conversion is usually permitted development in England unless the house is listed, an Article 4 direction applies, or it is on an estate where the planning permission removed permitted development rights. We check the original permission for your house.
What should Atherton homeowners check first?
- The garage floor is often lower than the house and needs raising.
- A bedroom needs an escape window or a protected route out.
From first call to completion
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
