Homes in County Londonderry
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 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 and building control applications to the council
- Planning check (some estates remove permitted development rights)
- Plastering, skirting and decoration-ready finish
What will a garage conversion cost?

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

What approvals does a garage conversion need in Northern Ireland?
Northern Ireland projects need planning clearance and building control approval from the local council. We prepare the applications and agree any work near neighbouring property directly with the neighbours.
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.
- Losing a parking space can matter on streets with permit parking.
From first call to completion
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
What people ask before starting
Do I need planning permission for a garage conversion?
Usually not if the work is internal and your permitted development rights are intact. Some estates remove those rights, so we check.
Does it need building regulations approval?
Yes, because it becomes a habitable room.
Can you visit a house in Derry to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
