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 does a garage conversion involve?
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
- Garage door removal and brick infill with window

Planning and building rules in Llangefni
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 Llangefni homeowners check first?
- The garage floor is often lower than the house and needs raising.
