Many Halesowen homes have more space than you’d think. It’s just sitting above the bedroom ceiling. Loft conversions in Halesowen turn that roof space into a room you can use all year round.
We work across Hasbury, Hayley Green, Cradley, Hawne and Lapal. Lots of homes here are semis and terraces, so rear dormers and hip-to-gable designs are often a good fit.
As loft conversion specialists in Halesowen, we manage the design, approvals and construction from survey to handover.

A closer look at recent J M A Group builds from groundworks to finished space.
You’ll live with your loft conversion for years. Here’s how we make sure it’s done properly.
1. Design & Construction Coordination
Design and build sit with one team. You won’t be stuck between an architect’s drawing and a builder’s opinion.
2. Structural Coordination
If your roof needs steels, we arrange the structural design. Then our team installs it to those exact details.
3. Defined Scope of Works
We agree a clear scope of works with you. It spells out what’s included, so there’s no guesswork later.
4. Professional Project Management
Your project manager plans each trade and visit. Your Halesowen build keeps moving without you chasing anyone.
5. Quality Control
We check quality throughout, not just at handover. That includes work you’ll never see once it’s boarded over.
6. Building Regulations
The loft is designed and built to Building Regulations. Building control inspects the key stages along the way.
7. Wider Renovation Capability
If your plans include an extension or refurbishment, we can bring it all together under one programme.
We start with a conversation about your home, your plans and your budget. It's free and there's no obligation.
We assess the loft's height, roof type and structure. Then we tell you honestly what it can and can't become.
We develop a layout that works for you, from bed position to storage. Changes are easy at this stage.
We confirm whether your Halesowen loft falls under permitted development or needs an application to Dudley Council.
Structural and Building Regulations details are drawn up. They cover the new floor, stairs, fire protection and insulation.
You get an itemised quote linked to the agreed design. If you add something later, you'll see the cost first.
Construction runs in clear stages: structure, roof, first fix, insulation, plastering, second fix and decoration.
We oversee the trades and inspect each stage. Snags are fixed before we call the job complete.
1. Dormer Loft Conversions
Dormers create straight walls and a flat ceiling where the slope used to be. A dormer loft conversion in Halesowen can greatly increase your usable floor area.
2. Rear Dormer Conversions
A rear dormer faces the garden and is usually hidden from the road. It’s a practical choice for terraced and semi-detached homes.
3. Hip-to-Gable Loft Conversions
A hip-to-gable replaces the sloping side roof with a straight wall. It makes room for a proper staircase and a larger bedroom.
4. Rooflight / Velux-Style Loft Conversions
A rooflight loft is the least disruptive option. It works best where the roof is already tall enough to stand up in.
5. Mansard Loft Conversions
Mansards suit some terraced streets and give near-full-height space. They usually need full planning permission.
6. Bedroom Loft Conversions
Add a double bedroom without losing any garden. It’s ideal for growing families or regular overnight guests.
7. Master Bedroom Suites
A top-floor master suite gives you a space of your own. Add wardrobes, a seating area and an en-suite if there’s room.
8. Loft Conversions with En-Suites
We design en-suites around head height and drainage. You get a shower room that’s comfortable to use, not cramped.
9. Home Office Loft Conversions
A loft office keeps work out of the living room. You’ll have a separate space to focus and a door to close.
10. Loft Conversion and Renovation Projects
Doing more than the loft? We can include it in a wider home renovation in Halesowen and manage it all together.
11. Loft Structural Alterations
Steel beams, new joists and trimmed rafters are part of most conversions. We install them to the engineer’s design.
12. Staircase Installation
The stairs need enough headroom and a safe landing. We plan them early, because they affect the rooms below.
13. Roof Alterations and Strengthening
We check the roof timbers and strengthen them where needed. That way the roof can carry the new room safely.

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
Halesowen is in Dudley borough, so applications go to Dudley Council. Many loft conversions don’t need full planning permission, as they fall under permitted development. A Lawful Development Certificate can confirm this in writing. We’ll advise which route suits your home.
Probably. If steels sit on or cut into the shared wall, the Party Wall etc. Act 1996 applies. You must serve notice on your neighbour before work starts. We’ll explain what’s needed and when.
In most cases, yes. We need enough head height for the shower and a sensible route for the waste pipe. We look at both during the survey.
Yes. A loft office is separate from the busy rooms downstairs. Rooflights give good daylight, and there’s usually space for storage in the eaves.
Every loft is different, so we don’t guess. Cost depends on the type, size, structure and finishes. We provide an itemised quote after a free survey.
More space could be closer than you think.
Book a free survey with our loft conversion company in Halesowen. We’ll look at your roof, talk through ideas and give you a clear, itemised quote.
