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.
In Stourbridge, as anywhere in West Midlands, the price of a garage conversion is driven mainly by size, materials and access. Across the West Midlands our guide sits at £12,000–£27,500 with VAT, but restricted parking, a narrow side passage or extra preparation can move the figure either way. That is why every price we give follows a visit to the house.

Local housing and a garage conversion
Red-brick Victorian and Edwardian terraces are common in the inner areas of Birmingham, Wolverhampton and the Black Country, ringed by large swathes of 1930s semis with bay windows and hipped roofs. You'll also find post-war council estates, some system-built blocks, Coventry's rebuilt centre and larger detached homes in Solihull and Sutton Coldfield.
1930s semis often suit side and rear extensions, hip-to-gable loft conversions and garage conversions. Victorian terraces tend to need repointing, roof work and replacement windows, and many have room for a side-return extension.
If your house in Stourbridge fits one of these patterns, it helps us anticipate what a garage conversion will involve, though we always confirm the details on site.
Planning and building rules in Stourbridge
Because Stourbridge falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
In England, converting an attached or integral garage into a room usually needs no planning permission, unless a planning condition on your estate has removed permitted development rights (common on newer houses). Changing the garage door to a wall and window is generally fine.
Building Regulations approval is needed: foundations for the infill wall, a damp-proof course, 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.
The four stages
A visit to your home
It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about a garage conversion.
Your fixed price
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.
Booking the work
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
On site to finish
Our trades complete a garage conversion while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
How we work
Garage conversions in Stourbridge: questions
Do I need planning permission for a garage conversion?
Whether a garage conversion needs planning permission depends on the works, your home's location, whether it is listed or in a conservation area, and which UK nation you are in. In England, converting an integral or attached garage is often permitted development where changes are mostly internal, unless a planning condition has removed those rights, which is common on newer estates. We check what applies 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.
Do you cover Brierley Hill, Kingswinford and Dudley?
Yes. As well as Stourbridge, we cover Brierley Hill, Kingswinford and Dudley and the rest of West Midlands. 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.
How much will a garage conversion cost in Stourbridge?
As a guide, expect to pay £12,000–£27,500 including VAT for a garage conversion in Stourbridge. That range is adjusted for the West Midlands, which runs about 2% below the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
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.
Nearby towns
We survey and quote throughout Stourbridge's DY5, DY8 and DY9 postcodes and in surrounding places such as Brierley Hill, Kingswinford and Dudley. The process and pricing approach are identical in each of them.
