A garage conversion turns an integral or attached garage into a warm, habitable room by insulating the floor, walls and ceiling, replacing the garage door with a wall and window, and adding heating, lighting and finishes.
Across Powys, people look into a garage conversion to replace something worn out, to make the house work better for them, or to get it ready for a sale. We cover Newtown, Brecon, Welshpool and Glyn-neath and the smaller towns around them, working to the rules that apply in Wales. Expect a guide of £11,000–£26,000, VAT included, in Wales, and every quote follows a free visit.

Housing across Powys
Powys is largely rural, with stone farmhouses and cottages under slate roofs, and timber-framed black-and-white buildings in Montgomeryshire towns near the English border. Brecon has Georgian streets, Llandrindod Wells has Victorian spa-town villas, and towns such as Newtown and Welshpool mix older centres with post-war and newer estates.
Stone and timber-framed homes need breathable lime finishes and careful roof repairs. Rural homes commonly take extensions, porches and driveways, and town terraces suit loft conversions and window replacement.
Upland weather dominates, with heavy rain, snow and hard frosts on higher ground, and remote sites can need extra planning for access and deliveries.
Planning and building rules in Powys
For anyone in Powys, the relevant framework is Wales's. The summary below is general, so we always contact the council about your address before putting a price in writing.
In Wales, an internal garage conversion usually needs no planning permission unless your planning history removed those rights.
Building Regulations approval in Wales is needed for the infill wall, insulation, ventilation and fire safety.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
Free site survey
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a garage conversion, and photograph or measure anything the quote needs to reflect.
Quote in writing
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a garage conversion.
Plan and prepare
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a garage conversion are in place before the first day on site.
On site to finish
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Questions about a garage conversion in Powys
Do I need planning permission in Powys?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Powys is in Wales, so Wales's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Will losing the garage affect parking?
Losing a garage can matter if your street has parking pressure or your property deeds or planning conditions require off-street parking. Many garages are too narrow for modern cars, so in practice the driveway often provides the parking anyway. We check for planning conditions affecting the garage before quoting. If you need extra parking, we can also price a driveway extension.
Can I keep some storage space?
Many people keep part of the garage for storage by building a dividing wall, leaving a smaller store at the front behind the existing door and converting the area behind into a room or utility. This keeps the look of the house unchanged and gives you somewhere for bikes and tools. The converted part still needs the same insulation, ventilation and fire separation.
Do you cover Newtown, Brecon and Welshpool?
Yes. As well as Powys, we cover Newtown, Brecon and Welshpool and the rest of Powys. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
Does the floor need raising?
Garage floors are usually lower than the house floor and slope towards the door for drainage. Most conversions raise the floor with a damp-proof membrane, insulation and either a screed or a timber floor, so it lines up with the house and removes the step. The final level depends on ceiling height and the door into the house. We measure both during the survey.
