Many homes in Sutton Coldfield have a garage that rarely sees a car. It’s become a store for bikes, tools and boxes. Converted well, it can give your family a whole new room.
J M A Group designs and builds garage conversions in Sutton Coldfield as one managed service. We look after the survey, drawings, approvals and construction. You get a single point of contact and an itemised quote.
From Four Oaks and Mere Green to Walmley and Boldmere, garages vary widely. Some are integral, while others are attached or detached. We survey yours first, so the design and price fit your home.

A closer look at recent J M A Group builds from groundworks to finished space.
We combine design, construction and project management in one service. Here’s how that benefits you.
1. A Single, Coordinated Team
There’s no need to manage separate designers and trades. We coordinate everyone and take responsibility for the result.
2. Transparent Scope and Pricing
Your scope of works is agreed in writing before we begin. The quote shows each element clearly.
3. Managed From Day One
A project manager plans the work and runs the site. Each trade is booked in at the right time.
4. Stage-by-Stage Quality Checks
We inspect each stage of the conversion as it’s completed. Small issues are fixed before they’re hidden.
5. Technical Expertise
Where steels, new lintels or floor works are needed, we plan them properly. Structural design is part of the process.
6. Approvals Handled
We confirm the planning position and prepare Building Regulations details. You don’t have to deal with the paperwork alone.
7. Room for Wider Plans
Thinking about an extension or new kitchen as well? We can manage both as one project.
We discuss what you'd like the room to become. We'll also cover budget, timing and any must-haves.
We survey your Sutton Coldfield garage in detail. Structure, levels, drainage and access are all checked.
We design a layout that feels part of the main house. Light, heating and storage are all considered.
We confirm whether your home needs planning permission. Then we prepare the Building Regulations details.
You get a detailed scope and an itemised quote. Everything included is listed clearly.
We replace the garage door with an insulated wall and window. The floor, walls and ceiling are upgraded and finished.
Your project manager coordinates the trades and checks quality. You'll get regular updates as work progresses.
We inspect the finished room with you. Any snags are put right before we hand over.

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![]()

Often not, if the work is internal and the outside changes little. Conservation areas and planning conditions can affect this. We’ll check your property’s position before any work starts.
Yes, it’s one of the most popular choices. We plan power, lighting and heating into the design. You’ll have a quiet, separate space to work.
Yes. Building control checks the structure, insulation, damp proofing, ventilation and fire safety. We prepare the details and coordinate the inspections.
Usually, yes. Garage floors often sit lower than the house. We raise and insulate the floor so it lines up with your home where possible.
Yes. A partial conversion keeps space at the front for storage. The rest becomes a warm, insulated room.
