Covering Caernarfon
We work in Caernarfon (LL55) and the places around it, including Llangefni, Bangor and Pwllheli.
Homes in Gwynedd and Anglesey
Across Wales you find valley terraces, coastal towns, rural stone houses and newer estates, so access, slopes and local materials all feature in the design.
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.
- Planning and building regulations checks under Welsh rules
- Planning check (some estates remove permitted development rights)
- Plastering, skirting and decoration-ready finish
How much should I budget for a garage conversion?
Typical ranges for garage conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Garage conversions | Guide price incl. VAT |
|---|---|
| Single integral garage | £12,000 to £17,000 |
| Single attached garage | £12,000 to £24,000 |
| Single detached garage | £18,000 to £30,000 |
| Double garage | £25,000 to £54,000 |
What approvals does a garage conversion need in Wales?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
In Wales, converting an attached garage usually does not need planning permission unless rights have been removed by condition or the building is listed.
What can affect a garage conversion?
- Some new-build estates have a planning condition keeping garages for parking.
- A bedroom needs an escape window or a protected route out.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
