Is your garage pulling its weight? For most households, the honest answer is no. It’s space you own but rarely use.
J M A Group turns that space into somewhere you’ll want to spend time. We design and build garage conversions in Smethwick as a complete service. Drawings, approvals, construction and finishing all sit with one team.
From Bearwood to Cape Hill, homes here vary in style and age. So we never price a conversion without seeing it first. Your quote is itemised and based on a proper site survey.

A closer look at recent J M A Group builds from groundworks to finished space.
Here’s what you get when you choose us for your garage conversion.
1. Design, Management and Build
We handle all three, so you aren’t left coordinating trades. It’s simpler for you and easier to keep on track.
2. Clarity From the Start
A defined scope sets out the agreed work in plain terms. You’ll know what’s happening and what it costs.
3. Experienced Project Managers
Your project manager plans the programme and runs the site. Each trade knows when to arrive and what to do.
4. Workmanship Monitored
We check quality throughout the build, not just at handover. Issues are dealt with as soon as they appear.
5. Structural Coordination
Some garages need new lintels or foundation work. We arrange structural input so it’s done right first time.
6. Meeting Building Regulations
Your converted garage has to meet current standards. We handle the technical detail and building control inspections.
7. Ready for Bigger Projects
If your conversion is part of a wider renovation, we can manage both. You keep one team for the whole home.
We start by understanding your goals for the room. We'll also talk about budget and timescales.
We survey your Smethwick garage and how it links to the house. Foundations, walls, roof and services are all assessed.
We plan a layout that works for daily life. Daylight, heating and power points are considered early.
We confirm whether Sandwell Council needs to approve the work. Building Regulations details are prepared in advance.
We set out a detailed scope with an itemised quote. Every cost is clear before you commit.
We infill the doorway, upgrade the floor and insulate the walls and ceiling. Then we plaster, wire and finish the room.
We manage the trades and inspect each stage of work. You'll get clear updates throughout the build.
We check the finished room carefully with you. Any snags are resolved before we sign off.
We’ll help you decide how best to use the space. As garage conversion builders in Smethwick, we regularly create:
– Guest and family bedrooms
– Home offices for remote working
– Living rooms and snugs
– Playrooms and teen dens
– Home gyms
– Utility rooms and boot rooms
– Bedrooms with en-suite shower rooms
– Partial conversions with storage at the front
We work on integral, attached and detached garages. Planning a wider project? Read about our home renovations in Smethwick or our main garage conversion service.

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![]()

Amazing work by Sunnie and the JMA team. Definitely worth the money and has added value to my house
Book a free consultation and we’ll survey it. We check the foundations, walls, roof and floor levels. Then we’ll explain what’s needed to make it a habitable room.
Often not, as many conversions fall under permitted development. Some homes have conditions that remove those rights. We’ll check your property with Sandwell Council before work starts.
Yes, in most cases. The room needs proper insulation, ventilation and a safe escape route. We design these in and get Building Regulations approval.
That’s the aim. We plan floor levels, finishes and the new front wall to blend in. Inside, it should feel like it’s always been part of your home.
Costs vary with size, condition and specification. Adding plumbing or a new window changes the price too. You’ll get an itemised quote after our site survey.
You don’t need to move house to get more space. The answer may already be behind your garage door.
As garage conversion specialists in Smethwick, J M A Group guides you from first idea to finished room. We handle the design, approvals and build in one service.
