Sooner or later, many homes start to feel a size too small. Building out can be simpler than moving. We create home extensions in Oldbury that fit family life.
Oldbury has lots of terraced and semi-detached homes on compact plots. Smart design matters here, so we plan every metre carefully to give you the most usable space possible.
J M A Group runs your project from first drawing to final inspection. As house extension builders in Oldbury, we price every item and link payments to finished stages.

A closer look at recent J M A Group builds from groundworks to finished space.
1. Design & Construction Under One Service
We don’t hand your drawings to another firm to build. Design and construction stay with one team throughout.
2. Construction Management
Scaffolders, bricklayers, roofers and electricians all report to us. We keep them working in the right order.
3. Defined Scope of Works
Every item of work is listed and agreed upfront. There are no grey areas about what you’re paying for.
4. Stage Payment Structure
Payments track the build’s progress. Foundations, walls, roof and finishes each have their own agreed amount.
5. Quality Control
We look for problems early, when they’re easiest to fix. Nothing moves forward until the current stage meets our standard.
6. Professional Communication
Your project manager answers your calls and messages. You’ll always know what’s happening on site this week.
7. One Team for Larger Renovations
Lots of clients use the extension as a chance to fix up the rest of the house. We’re happy to quote for that too.
Fill in our online form or give us a ring. Tell us what's not working in your current space.
We chat through your ideas, priorities and budget. Then we outline the options that fit.
We come to your Oldbury home to look at the site. Boundaries, drains, access and structure are all checked.
Plans and structural details are drawn up where required. Approvals are applied for before any building starts.
We give you a written scope with each item priced. You'll see exactly what you're signing up for.
Together we set a start date and build timetable. Then the groundworks begin.
Your project manager coordinates the trades on site. Building control inspects the work at the required stages.
We complete the finishes and fix any small snags. After a final check together, the room is ready for furniture.
1. Single-Storey Extensions
Add extra room on the ground floor without touching the upstairs. Ideal for a kitchen, dining or family space.
2. Double-Storey Extensions
Gain space on both levels from one build. A good fit for families who need another bedroom.
3. Rear Extensions
Extend into the garden and bring in more daylight. Even a modest depth can make a big difference.
4. Side Return Extensions
Many Oldbury terraces have a side passage that’s barely used. Building into it widens your kitchen without losing garden.
5. Wraparound Extensions
Wrap the extension around the side and rear of your home. A wraparound extension in Oldbury gives you a large, open ground floor.
6. Kitchen Extensions
Make space for proper worktops, a dining table and storage that actually fits. A bigger kitchen changes how the whole house feels.
7. Open-Plan Kitchen and Living Extensions
Combine kitchen, dining and lounge into one shared room. Mealtimes, homework and TV can all happen in one bright space.
8. Utility and Boot Room Extensions
Create a space for laundry, coats and outdoor gear. It keeps the busiest parts of the house tidy.
9. Additional Bedroom Extensions
Give each child their own room or make space for guests. You get more room without the move.
10. Home Office Extensions
A proper home office keeps work and family life apart. Good light and storage make long days easier.
Not always. Single-storey rear extensions within permitted development limits can go ahead without it. Bigger or two-storey designs usually need approval from your local council. We’ll confirm after the site visit.
Yes. End-of-terrace homes often have side space that’s ideal for extending. A side or wraparound extension can add a lot of room. Party wall notices may be needed for the attached neighbour.
More than you might think. Careful layouts, roof lanterns and wide glazing make modest extensions feel bigger. We’ll show you what fits your plot at the survey.
It’s official confirmation that your extension counts as permitted development. It isn’t always required, but it helps when you sell the home later. We can advise whether it’s worth applying for.
It’s a popular choice. Underfloor heating frees up wall space and keeps open-plan rooms evenly warm. It works well with a new screed floor laid during the build.
Write down the three things that frustrate you most about your home right now. A cramped kitchen? No space to work? Too few bedrooms? Bring that list to us, and we’ll show you how an extension could fix it.
