We work across Great Barr, Hamstead, Charlemont, Yew Tree, Stone Cross and Hill Top. Many homes here are semis and terraces with hipped or gabled roofs, and each opens up different options.
As loft conversion contractors in West Bromwich, we manage the design, approvals, structure and finishing for you.

A closer look at recent J M A Group builds from groundworks to finished space.
The best loft conversions feel like they were always part of the house. That comes down to good planning and good management.
1. Design & Construction Coordination
We design the loft and build it, so nothing gets lost between the drawings and the site.
2. Structural Coordination
Your structural engineer’s design is built exactly as specified. Steels, joists and roof changes are all coordinated.
3. Defined Scope of Works
We agree a written scope with you before work starts. It removes any doubt about what’s included.
4. Professional Project Management
A project manager runs your West Bromwich job from start to finish. You always have one person to contact.
5. Quality Control
We check every stage as we go. Structure, insulation, plaster and joinery are inspected before moving on.
6. Building Regulations
Building Regulations are built into the design from the start. We submit the plans and keep building control updated.
7. Wider Renovation Capability
Want to update other rooms at the same time? We can combine your loft with wider work under one contract.
We discuss your goals, budget and timescale. It's a relaxed chat to see if a loft conversion is right for you.
We measure the loft and check the roof structure. That tells us what your West Bromwich home can realistically gain.
We draw up a layout and talk it through with you. Small tweaks now make a big difference later.
We confirm whether permitted development applies. If not, we prepare a planning application to Sandwell Council.
Structural calculations and Building Regulations drawings are completed. Fire safety, insulation and stairs are all covered.
You get an itemised quote tied to the final design. Every line is explained, so you can decide with confidence.
We alter the roof, install the structure and make it weathertight. Then we insulate, plaster and fit out the room.
Your project manager checks every stage. We finish with a walk-round, so you're happy before handover.
1. Dormer Loft Conversions
A dormer extends out from the roof slope to give you standing room. A dormer loft conversion in West Bromwich suits many semis and terraces.
2. Rear Dormer Conversions
A rear dormer gives the biggest gain on the garden side. From the street, your home looks almost the same.
3. Hip-to-Gable Loft Conversions
Got a hipped-roof semi? Converting the hip to a gable opens up the loft and frees space for the stairs.
4. Rooflight / Velux-Style Loft Conversions
Rooflights are a lower-impact option. They work where the roof is already high enough and keep the roofline as it is.
5. Mansard Loft Conversions
A mansard creates a large room with steep, near-vertical walls. It usually needs planning permission from the council.
6. Bedroom Loft Conversions
An extra bedroom can transform a crowded house. It’s often quicker and simpler than moving home.
7. Master Bedroom Suites
A master suite gives you a calm space away from the rest of the household. Add wardrobes and an en-suite if space allows.
8. Loft Conversions with En-Suites
Add a shower room next to your new bedroom. We plan drainage and ventilation early to keep the layout practical.
9. Home Office Loft Conversions
A loft office gives you a proper workspace. It’s quieter than the dining table and easy to shut away.
10. Loft Conversion and Renovation Projects
Taking on more around the house? We can combine your loft with a wider home renovation in West Bromwich.
11. Loft Structural Alterations
We install steels, new joists and supports to the engineer’s design. They’re the backbone of your new room.
12. Staircase Installation
The staircase affects the floor below as well as the loft. We design it to fit well and meet the headroom rules.
13. Roof Alterations and Strengthening
If roof timbers need attention, we deal with it during the build. Your new room sits on a sound, strengthened roof.

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
Many loft conversions don’t. Rear dormers and hip-to-gables often fall under permitted development. Front dormers and mansards usually need permission from Sandwell Council. We’ll check your home and confirm the right route.
On a hipped-roof semi, it often is. It creates far more usable floor space than rooflights alone. Many people combine it with a rear dormer for even more room.
Usually a protected escape route down the stairs, fire-resisting doors onto the stairway and mains-powered, interlinked smoke alarms. We design these into your plans to meet Building Regulations.
Usually not. Much of the work is done from the scaffold outside. There is some disruption when the staircase goes in, but we’ll plan it with you.
It depends on the type, size and specification. We give an itemised quote after a free survey, so you have real figures to work from.
The space you need could be sitting right above you.
