Many Halesowen homes have a garage that’s barely used. It holds the lawnmower, a few boxes and not much else. Yet it could easily become your next bedroom, study or snug.
J M A Group plans and builds garage conversions in Halesowen as one complete service. We take care of the drawings, approvals, building work and finishes. You’ll have one team to speak to throughout.
Homes here range from older semis in Hasbury to newer houses around Hayley Green. Each garage is built differently, so each one gets a proper survey. Then we give you an itemised quote based on what we find.

A closer look at recent J M A Group builds from groundworks to finished space.
Converting a garage is a building project, not just a makeover. Here’s why homeowners trust us with theirs.
1. Design and Build Together
The people who design your room also plan how it’s built. That keeps ideas realistic and avoids costly redesigns.
2. A Clear, Written Scope
We put the full scope in writing before work begins. You’ll see what’s included and what isn’t.
3. Organised Site Management
Trades are booked in the right order and supervised on site. Your project keeps moving without long pauses.
4. Ongoing Quality Checks
We inspect the work at key stages, not only at the end. Small issues are caught before they become bigger ones.
5. Structural Know-How
If your garage needs new footings or a steel, we’ll plan for it. Structural design is brought in wherever it’s needed.
6. Compliance Covered
Building Regulations apply to every garage conversion. We prepare the details and work with building control for you.
7. More Than One Project
Thinking about a loft or kitchen next? We can plan several improvements together as one project.
We talk through how you'll use the new room. We also discuss budget, timing and any must-haves.
We visit your Halesowen home and inspect the garage closely. We note its size, structure, levels and access.
We create a layout that feels like part of the house. Doors, windows and services are all planned in detail.
We check which approvals your conversion needs. Building Regulations details are prepared before work begins.
You receive a clear scope and an itemised quote. It's easy to see where every pound is going.
Our team builds the new front wall, then insulates and fits out the room. We keep the site tidy as we work.
A project manager coordinates the trades and checks quality. You get regular updates as the build progresses.
We complete a final inspection with you. Any small snags are put right before handover.
No two garages are quite the same. We’ll help you choose the conversion that suits your space and plans. As garage conversion specialists in Halesowen, we handle:
– Integral and attached garage conversions
– Detached garage conversions
– Garage to bedroom conversions
– Garage to study or home office
– Garage to snug or second lounge
– Garage to children’s playroom
– Garage to utility and boot room
– Garage conversions with a WC or shower room
– Partial conversions that keep storage space

I recently had an initial visit with Sunnie from JMA regarding my planned single-storey wrap-around extension. Although the visit had to be rearranged twice due to unforeseen circumstances, this was handled in a timely and professional manner. When Sunnie came out for the initial visit, he took the time to listen to my vision for the project and we discussed various options, including planning, design, materials, timescales and costs. He was professional, friendly and accommodating to my suggestions, while also being very solution-focused and offering practical ideas. He provided an overall estimated cost for the build and even offered me a discount as a Blue Light Card holder, which was a really welcomed gesture. Following the initial visit, I have decided to go ahead with Sunnie and JMA for my project. I feel confident in my decision and am really looking forward to seeing my plans come together over the coming months.Posted on Google![]()

Sunnie came down promptly to give a quote. He worked with my budget which was my main concern and a high priority for me. Seems very professional and happy to make tweeks and changes and listened to all my ideas which lead us to go over the consultation time by a mile.

Amazing work by Sunnie and the JMA team. Definitely worth the money and has added value to my house
Often, yes. Many internal conversions count as permitted development. But some homes, especially on newer estates, have had these rights removed. We’ll check this with Dudley Council before you commit.
Yes, for any garage being turned into a habitable room. Building control checks the structure, insulation, ventilation and fire safety. We prepare the details and arrange the inspections.
Yes. A partial conversion keeps space at the front for storage. The back becomes a warm, insulated room. It’s a popular choice for keeping bikes and tools out of the house.
It should be. Building Regulations set insulation standards for walls, floors and ceilings. We also plan heating and ventilation into the design from the start.
It depends on the size, structure and finish you choose. Adding a bathroom or new windows also affects the price. We’ll give you an itemised quote after a free consultation.
You don’t always need to move to get the space you need. Sometimes it’s already there, sitting behind your garage door.
J M A Group can turn it into a room your family uses every day. As garage conversion builders in Halesowen, we take care of the whole project.
