Most garages end up full of boxes, not cars. That space could become your next bedroom, office or family room. We turn tired garages into warm, finished rooms you’ll use every day.
J M A Group delivers garage conversions in Birmingham from our studio in St Paul’s Square. One team handles the design, approvals, build and finish. You get a single point of contact and a clear, itemised quote.
From 1930s semis to modern estate homes, every garage is built differently. We check the walls, floor and foundations before we price anything. So your quote reflects your actual garage, not a guess.

We offer a joined-up design, management and build service. Here’s what that means for your project.
1. One Team From Start to Finish
You won’t need to hire a designer, builder and trades separately. We bring them together and manage them for you.
2. A Clear Scope of Works
Before work starts, we set out exactly what’s included. You’ll know what you’re paying for, line by line.
3. Hands-On Project Management
A project manager runs your site and plans each trade. Work moves forward in the right order, without long gaps.
4. Quality Checks at Every Stage
We inspect the work as it goes up, not just at the end. Problems are fixed early, before they get covered up.
5. Structural and Technical Input
Some garages need new lintels, a raised floor or extra support. We bring in structural design wherever your build needs it.
6. Building Regulations Handled Properly
A converted garage must be warm, dry, safe and well ventilated. We work with building control so your new room meets the rules.
7. Room to Do More
Planning a kitchen refit or extension as well? We can add it to the same project and programme.
Tell us how you want to use the space. We'll talk through your ideas, budget and must-haves.
We visit your Birmingham home and survey the garage. We check the walls, floor, roof and foundations.
We draw up a layout that suits how you live. Windows, heating and storage are planned from day one.
We check whether Birmingham City Council needs a planning application. Then we prepare the details building control will need.
You get a written scope and an itemised quote. Each part of the work is listed clearly.
We infill the door opening, insulate the shell and fit out the room. Each trade arrives in the right order.
Your project manager keeps the build on track day to day. We check each stage before moving on.
We walk through the finished room with you. Any snags are sorted before we hand over.

Often not, if the work is mainly internal and the outside barely changes. Some homes have lost permitted development rights through planning conditions. Conservation areas can also bring extra rules. We’ll check your property with Birmingham City Council before work starts.
Yes. Turning a garage into a habitable room needs building control sign-off. This covers insulation, ventilation, fire safety, damp proofing and the new front wall. We prepare the details and arrange the inspections.
It depends on the garage, the design and any approvals. A simple integral conversion moves faster than a detached one with a bathroom. We’ll give you a realistic programme once the scope is agreed.
Often, yes. The main checks are drainage, water supply, ventilation and the layout. We look at all of these during the site survey. Then we’ll tell you honestly what’s possible.
Yes. A partial conversion keeps a section at the front for bikes, tools and bins. The rest becomes a fully insulated room. We’ll design the split around what you need to store.
Your garage is already part of your home. It just isn’t working hard for you yet. With the right design, it becomes a room you’ll use every day.
As garage conversion builders in Birmingham, J M A Group takes care of the whole job. We survey, design, manage and build, then hand over a finished space.
