Your home suits you, but the space just isn’t there anymore. Rather than moving, extend. We design and build home extensions in Wolverhampton that fit around family life.
Wolverhampton has everything from Victorian villas and terraces to 1930s semis and newer estates. We match each design to your home’s age, style and the space available.
As house extension builders in Wolverhampton, we manage the full project, including plans, approvals and construction. You’ll have one contact throughout. Costs are itemised and paid in stages.

A closer look at recent J M A Group builds from groundworks to finished space.
1. Design & Construction Under One Service
We draw it, plan it and build it. One firm takes full responsibility from concept to completion.
2. Construction Management
Our team schedules every trade and delivery. Your build runs to an organised plan, not guesswork.
3. Defined Scope of Works
We put the full list of works in writing. You’ll know what’s included before a single brick is laid.
4. Stage Payment Structure
Payments are tied to agreed stages of the build. You release each one as that stage is completed.
5. Quality Control
Standards are checked regularly on site. Small issues are fixed straight away, before they become big ones.
6. Professional Communication
We keep updates simple and regular. You’ll always know what’s done, what’s next and who’s on site.
7. One Team for Larger Renovations
Planning wider improvements too? We can combine your extension with a kitchen, bathroom or full refurbishment.
Contact us online or by phone. A few details about your home are all we need to start.
We discuss what you want from the new space. Budget, style and timescales are all covered.
Our team visits your Wolverhampton home to assess the site. We note access, existing walls and ground conditions.
We prepare plans and structural details where required. Planning and Building Regulations applications are supported at this stage.
You get a clear scope with every cost broken down. No vague totals, just honest figures.
We set a start date and share the programme. Work then begins on site in planned stages.
A project manager coordinates everyone on site. Each stage is checked and signed off before moving on.
We finish the details, snag the work and clean up. Then we walk through your new space together and hand it over.
1. Single-Storey Extensions
Create extra room on the ground floor in one straightforward build. Ideal for a family kitchen, lounge or playroom.
2. Double-Storey Extensions
Add space on two levels at the same time. You get downstairs living space and an upstairs bedroom, built together.
3. Rear Extensions
Extend towards the garden for a bright, sociable room. Wide glazing helps link the house with your outside space.
4. Side Return Extensions
Use the passage alongside your home to widen the kitchen. A neat fix for narrow terraced layouts.
5. Wraparound Extensions
Extend along the side and back of your house. A wraparound extension in Wolverhampton completely transforms your ground floor.
6. Kitchen Extensions
Plan the kitchen around how you really live. Add room for an island, a dining table and plenty of storage.
7. Open-Plan Kitchen and Living Extensions
Bring your kitchen, dining and lounge areas together. One open room that feels light, spacious and easy to share.
8. Utility and Boot Room Extensions
Give muddy boots, coats and laundry their own home. Your hallway and kitchen stay clear and calm.
9. Additional Bedroom Extensions
Make space for a growing family or visiting relatives. An extra bedroom adds comfort without moving house.
10. Home Office Extensions
Set up a proper office at home. Somewhere quiet, comfortable and separate from family life.

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![]()

Sunnie came down promptly to give a quote. He worked with my budget which was my main concern and a high priority for me. Seems very professional and happy to make tweeks and changes and listened to all my ideas which lead us to go over the consultation time by a mile. Haven’t started the work yet but happy with the Sevice till now.Posted on Google![]()

Sunnie from JMA Group visited us and explained the entire extension process in great detail. He provided different options along with estimated costs on the same day. He appeared very professional throughout. He also mentioned that they build new houses and offer an NHBC warranty. This was our first meeting with them, and if we agree on the pricing, we look forward to working with themPosted on Google![]()

Applications go to City of Wolverhampton Council. Some extensions fall under permitted development instead. We’ll check what applies before design begins.
Yes. Older homes often need extra care with foundations and materials. We plan the structure and finish so the extension suits the original house.
There’ll be some noise and activity, especially early on. We keep the site tidy and agree working hours with you. You’ll know what’s happening each week.
Yes, within reason. Any change is priced and agreed with you first. That way, your budget stays under control.
Yes. Many extensions include a downstairs WC or shower room. We plan the drainage and ventilation into the design from the start.
Most people extend because their home no longer fits their life: more kids, more working from home, more family visits. Whatever’s changed, the right extension can help your home catch up.
