Need another room but don’t want the cost and upheaval of moving? Look at your garage first. For many families, it’s the easiest space in the house to reclaim.
J M A Group carries out garage conversions in Sandwell, managing the full project for you. We survey, design, gain approvals and build, all with one team. You get a written scope and a fully itemised quote.
We work across the borough, from Tipton to Rowley Regis. Every garage we survey differs in size, age and construction. So your design and price are based on your home, never a template.

A closer look at recent J M A Group builds from groundworks to finished space.
We don’t just send builders. We plan, design and manage the whole conversion for you.
1. A Single Point of Responsibility
One team is accountable for the design and the build. If a question comes up, you know exactly who to ask.
2. Scope Agreed Before Work Starts
Every item of work is written down and agreed upfront. That protects your budget and avoids misunderstandings.
3. Coordinated Trades
Builders, electricians, plumbers and plasterers are all scheduled by us. Each one arrives when the job is ready for them.
4. Regular Inspections
We check the work at every key stage. Quality is built in, not just inspected at the end.
5. Engineering Where Needed
If the structure needs strengthening, we bring in structural design. Calculations are sorted before construction starts.
6. Building Control Sign-Off
We prepare the technical details building control needs. Your garage is inspected and signed off as a proper habitable room.
7. One Contractor for Wider Works
Want a new bathroom or kitchen at the same time? We’ll fold it into one project with one programme.
We listen to what you want from the space. Then we discuss budget, priorities and possible layouts.
We visit your Sandwell home and survey the garage in detail. Measurements, structure, damp and drainage are all checked.
We produce a design that suits your family's routine. Lighting, heating and storage are planned at this stage.
We check whether Sandwell Council needs to grant planning permission. Building Regulations details are prepared before work begins.
Your scope and quote are set out line by line. Any optional extras are shown separately.
Work begins once everything is agreed. We build, insulate and finish the room to the agreed specification.
A dedicated project manager oversees the work. Each stage is checked before the next one starts.
We carry out a final snagging check with you. Then we hand over your finished room, clean and ready.
From compact single garages to large doubles, we can help. As garage conversion specialists in Sandwell, our work includes:
– Integral garage conversions
– Attached and detached garage conversions
– Double garage conversions
– Half-garage conversions that keep storage
– Garage to bedroom with en-suite
– Garage to home office
– Garage to playroom or family room

Need even more space? Our home extensions in Sandwell and loft conversions could help too.

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 from JMA Group visited us and explained the entire extension process in great detail. He provided different options along with estimated costs on the same day. He appeared very professional throughout. He also mentioned that they build new houses and offer an NHBC warranty. This was our first meeting with them, and if we agree on the pricing, we look forward to working with themPosted on Google![]()

Amazing work by Sunnie and the JMA team. Definitely worth the money and has added value to my house
Many don’t, because they fall under permitted development. However, some homes have had these rights removed by planning conditions. Listed buildings and conservation areas have extra rules too. We’ll check with Sandwell Council for you.
It depends on the garage’s size and condition, the design and any approvals needed. We’ll set out a realistic programme once the scope is agreed.
Yes, in many cases. It needs good insulation, plus power, lighting and heating. Planning rules can differ for detached buildings, so we’ll check first.
If your garage shares a wall with next door, the Party Wall Act may apply. We’ll explain whether a party wall notice is needed for your conversion.
Usually, yes. We build an insulated wall and fit a window to suit your home. We aim to match the brick and window style as closely as possible.
Your garage could be doing far more than storing clutter. Picture a quiet office, a guest bedroom or a playroom for the kids.
As garage conversion builders in Sandwell, J M A Group makes it happen from start to finish. One team, one plan and one clear price.
