Northern Ireland has a high proportion of detached houses and bungalows outside the cities, which often suit side extensions, rear extensions and upward extensions.
What is included in a garage conversion in Downpatrick?
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 control applications to the council
- Building control application
- Insulated floor, walls and ceiling
How much does a garage conversion cost in Downpatrick?
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 |

What approvals does a garage conversion need in Northern Ireland?
In Northern Ireland the council handles both planning and building control. Permitted development rules are set by the Planning (General Permitted Development) Order (Northern Ireland) 2015, and there is no party wall act, so we agree access and protection with neighbours in writing.
In Northern Ireland, garage conversions often do not need planning permission if the external changes are minor; building control approval is needed.
What should I think about before starting?
- Some new-build estates have a planning condition keeping garages for parking.
- The garage floor is often lower than the house and needs raising.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- 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.
