Covering Swindon
We work in Swindon (SN1, SN25, SN26) and the places around it, including Calne, Wantage and Chippenham.
Homes in the South West
The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.
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.
- Building control application
- Insulated floor, walls and ceiling
- Plastering, skirting and decoration-ready finish

| Single integral garage | £12,000 to £17,000 |
| Single attached garage | £12,000 to £24,000 |

What approvals does a garage conversion need in England?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
An internal garage conversion is usually permitted development in England unless the house is listed, an Article 4 direction applies, or it is on an estate where the planning permission removed permitted development rights.
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.
What are the steps?
- 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.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
