Covering Holyhead
We work in Holyhead (LL65) and the places around it, including Llangefni, Caernarfon and Bangor.
Homes in Gwynedd and Anglesey
Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.
What is a garage conversion?
Most integral garages already have the walls and roof; what they need is a new insulated floor, an infilled front wall with a window, and heating. We check whether your permitted development rights are intact, handle building control and finish the room ready to use.
- Planning check (some estates remove permitted development rights)
- Building control application
- Insulated floor, walls and ceiling
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 |
Do you need permission for a garage conversion in Holyhead?
Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
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 should Holyhead homeowners check first?
- Some new-build estates have a planning condition keeping garages for parking.
- The garage floor is often lower than the house and needs raising.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
