Yes. We tailor solutions to fit different budgets without compromising on quality. Our team will advise on cost-effective options to maximise value.
Extensions, lofts, garage conversions and full refurbishments delivered with control — not confusion.
At J M A Group, we manage new builds in Birstall with the same discipline as projects — structured planning, clear budgets, and controlled delivery — while designing homes that genuinely work for everyday living.
Whether you’re building your own home or developing property for sale, we bring clarity and control from day one.
Most self-builds and small developments in Birstall struggle because too many decisions are made too late.
We prevent that by planning everything upfront and managing the entire process under one team.
Commercial-level project management for residential builds
Early feasibility and buildability advice
Realistic cost planning and procurement strategy
Clear programmes with defined milestones
One accountable team from concept to completion
We don’t simply “build what’s drawn.” In Birstall, we challenge designs, manage risk, and deliver homes that perform as well on-site as they do on paper.
We start by understanding how you want to live in the space. Layouts, structural changes, and aesthetics are carefully planned to meet your goals — not just look good on paper.
Every design is reviewed from a construction perspective. We identify risks early, resolve technical challenges, and ensure what’s designed can be built efficiently and safely.
You receive a realistic, transparent budget — not guesswork. Costs are aligned with the design and scope so there are no unpleasant surprises halfway through the build.
We create a clear project timeline covering every phase of the renovation. You’ll know what’s happening, when it’s happening, and how long it will take.
Our team manages the entire build, coordinating trades, materials, and quality control. The result is a finished renovation delivered properly — not “nearly done”.
Seamlessly expand your living space with carefully planned rear, side, or wrap-around extensions.
Transform unused loft space into bedrooms, offices, or living areas that add real value.
Convert garages into functional, high-quality living spaces without compromising the structure.
Complete refurbishments for homeowners who want a fully reimagined home, inside and out.
Minimum project value: £30,000

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![]()
