Many homes in Sutton Coldfield have big roof spaces that sit empty. Loft conversions in Sutton Coldfield turn that space into rooms your family will use every day.
We work across Four Oaks, Mere Green, Walmley, Boldmere and Wylde Green. Large hipped roofs, older timber structures and conservation streets each need a slightly different approach.
As loft conversion experts in Sutton Coldfield, we design, manage and build your project under one contract.

A closer look at recent J M A Group builds from groundworks to finished space.
Bigger homes often mean bigger, more complex roofs. Here’s what you get when you work with us.
1. Design & Construction Coordination
One team designs your loft and builds it. That keeps the drawings practical and the build true to the plans.
2. Structural Coordination
Large hipped roofs often need substantial steels. We coordinate the engineer’s design with the build from the outset.
3. Defined Scope of Works
Your scope covers everything from dormer cladding to door handles. Clear detail now saves debate later.
4. Professional Project Management
Your project manager keeps the programme on track. You’ll always know what’s happening on site that week.
5. Quality Control
Each stage is checked before it’s covered over. Structure, insulation and fire protection all get a second look.
6. Building Regulations
Adding a floor brings stricter fire safety rules. We design the escape route, doors and smoke alarms to meet them.
7. Wider Renovation Capability
Planning a larger refurbishment of your Sutton Coldfield home? We can deliver the loft alongside it, with the same team.
We visit, listen to your plans and look at how your household uses the house. Then we suggest a sensible starting point.
We check ridge height, roof pitch and the existing structure. Larger roofs often hold more potential than people expect.
We plan rooms, storage and light around your roof. Large lofts can often take a bedroom, en-suite and dressing area.
We check permitted development first, then any conservation area limits. Applications go to Birmingham City Council.
Structural calculations and Building Regulations drawings are prepared. They cover steels, the escape route and insulation.
Your scope and itemised quotation set out every stage. You see what's included before you commit to anything.
The roof is opened, the new structure goes in and the shell is made watertight. Then the inside is insulated and finished.
We manage every trade and check each stage. At the end, we walk through the room with you before handover.
1. Dormer Loft Conversions
A dormer squares off part of the roof to give full standing height. A dormer loft conversion in Sutton Coldfield suits most semis and many detached homes.
2. Rear Dormer Conversions
Placing the dormer at the back keeps your front elevation unchanged. That matters on tree-lined roads where the street scene counts.
3. Hip-to-Gable Loft Conversions
Detached homes may have hips on both sides. We can convert one or both into gables to make the loft much larger.
4. Rooflight / Velux-Style Loft Conversions
If your roof is tall and steep, rooflights alone may work. It’s a lighter-touch conversion that keeps the roof profile.
5. Mansard Loft Conversions
A mansard creates a large, boxy room with near-vertical walls. It usually needs planning permission, so we allow for that early.
6. Bedroom Loft Conversions
A loft bedroom gives older children or guests a space of their own. It also frees up a room downstairs.
7. Master Bedroom Suites
Large roofs can hold a full master suite. Think bedroom, walk-in wardrobe and en-suite on a floor of their own.
8. Loft Conversions with En-Suites
We position the en-suite near the existing soil pipe where we can. It keeps pipe runs short and avoids bulky boxing.
9. Home Office Loft Conversions
A loft office keeps work away from family life. Rooflights or a dormer window give you good daylight at the desk.
10. Loft Conversion and Renovation Projects
Bringing the rest of the house up to date as well? We can deliver your loft within a wider home renovation in Sutton Coldfield.
11. Loft Structural Alterations
Opening up a large roof can mean long steel beams and new load paths. We install them to the engineer’s specification.
12. Staircase Installation
Bigger homes often have room for a generous staircase. We design one that feels in keeping with the rest of the house.
13. Roof Alterations and Strengthening
Older roofs can have undersized rafters or past repairs. We assess the timbers and add strengthening where it’s needed.

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
Planning in Sutton Coldfield is handled by Birmingham City Council. Many loft conversions fall under permitted development and need no application. Homes in a conservation area usually need full permission, and the town has several. We check your address and explain the right route.
It depends on your roof. Hipped roofs often suit a hip-to-gable with a rear dormer. Tall, steep roofs may only need rooflights. We compare the options after measuring your loft.
Adding a new storey changes the fire rules. You will usually need a protected escape route down the stairs, fire-resisting doors and mains-powered, interlinked smoke alarms. We design all of this into your Building Regulations plans.
Yes, in most cases. Larger lofts often have room for a shower room as well as a double bedroom. We check the head height and drainage routes during the survey.
Cost depends on size, structure and finish. A large conversion with an en-suite costs more than a simple rooflight loft. After a free survey, we send an itemised quote so you can see every cost.
A well-designed loft can feel like the best room in the house.
As your loft conversion company in Sutton Coldfield, we handle the survey, design, approvals and build. You get regular updates and one point of contact throughout.
