Need extra room without the stress of moving? We design and build home extensions in Sandwell that give families more space. Everything is handled by one team, start to finish.
Sandwell’s housing is really mixed, from Victorian terraces to interwar semis and modern estates. We study your property’s layout and plot before suggesting the right extension design.
As house extension builders in Sandwell, we coordinate drawings, structural work, approvals and construction. A dedicated project manager oversees your build. Payments follow clear, completed stages of work.

A closer look at recent J M A Group builds from groundworks to finished space.
1. Design & Construction Under One Service
Your extension is designed by the people who build it. Nothing gets lost between the plans and the site.
2. Construction Management
We take charge of the whole site. Trades, materials and timings are all organised for you.
3. Defined Scope of Works
Your scope lists every part of the job in plain terms. You sign it off before we break ground.
4. Stage Payment Structure
Your total cost is divided into agreed milestones. Each payment lines up with work you can see finished.
5. Quality Control
We keep a close eye on standards throughout the build. Defects are spotted and fixed as we go.
6. Professional Communication
You’ll never be left wondering what’s happening. We share progress and answer questions promptly.
7. One Team for Larger Renovations

Your project manager coordinates the trades daily. Inspections take place at each important stage.
We complete the last details and tidy the site. After a final walk-round, your new space is yours to enjoy.
1. Single-Storey Extensions
Extend on one level for a brighter, bigger ground floor. Perfect for a family kitchen or dining area.
2. Double-Storey Extensions
Add rooms upstairs and downstairs in a single build. A smart move for growing families who need bedrooms.
3. Rear Extensions
A rear extension in Sandwell opens your home up towards the garden. Add roof lanterns for plenty of natural light.
4. Side Return Extensions
Turn the alley beside your house into usable room. It’s a clever way to widen a narrow kitchen.
5. Wraparound Extensions
Build around the side and rear in one go. You get a large, open ground floor with real flexibility.
6. Kitchen Extensions
Get the kitchen you’ve always wanted, with space to cook, dine and gather. Great for families who love to host.
7. Open-Plan Kitchen and Living Extensions
One connected space for cooking, eating and unwinding. It makes a home feel larger and more social.
8. Utility and Boot Room Extensions
A practical spot for washing, wellies and school bags. It keeps clutter out of your main rooms.
9. Additional Bedroom Extensions
Add a bedroom for a new arrival, older kids or guests. You get more space without the upheaval of moving.
10. Home Office Extensions
A quiet room built for focus. Leave the laptop behind when the working day is done.
Applications go to Sandwell Metropolitan Borough Council. Some smaller extensions don’t need full planning permission. We’ll check which route applies to your home.
In most cases, yes. If you own the home, you can usually extend like any other property. Older deeds sometimes include restrictions, so it’s worth checking yours first.
Yes. We choose bricks, roof tiles and windows that blend with your home. The aim is an extension that looks like it was always there.
As early as possible. Design and approvals can take time before building starts. Getting in touch early helps keep your timeline realistic.
Yes. We prepare the technical details and liaise with building control. Inspections are carried out at key stages of the build.
Picture your home with a proper dining space, a spare bedroom or a quiet office. An extension can make that real, and you won’t need to change postcode to get it.
Our extension builders in Sandwell design and deliver single-storey, double-storey, wraparound and kitchen extensions. J M A Group runs the whole project, so you don’t have to. Book your site survey to get started.
