Renovation Should Feel Structured, Not Stressful
As a design and build West Midlands renovations company, we look after every stage. You won’t have to.
We’re not the cheapest quote you’ll get. But we’re the home renovation builder you won’t have to chase, check up on or call back to fix things.
It starts with a conversation, not a drawing. We ask how your family uses each room. Then we shape a layout that makes daily life easier.
Our site team checks every plan before it's signed off. Steels, drainage, access: we sort it early. That means fewer surprises once the work begins.
You get a clear, itemised price tied to the final design. Every line is explained. If something changes, you'll see the cost first.
We set out the full timeline before day one. You'll know which trades are coming and when. So you can plan your life around the build.
We manage the site from start to handover. Trades, materials and quality checks all sit with us. You walk into a finished home, with no snag list.
Rear, side or wrap-around extensions that feel like part of the original house. More room to cook, eat and relax together.
Your loft is often the easiest space to gain. We turn it into a bright bedroom, office or guest suite.
Most garages hold boxes, not cars. We convert yours into a warm, insulated room you’ll actually use.
Some homes need more than a facelift. As your home renovation builder, we handle rewiring, plumbing, layout and finishes under one contract.
We plan kitchens around how you cook and gather. Better flow, smarter storage and finishes that cope with busy family life.
From walk-in showers to full refits, we create bathrooms that look great. And they’re sealed and fitted to last.

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![]()
