Extensions, lofts, garage conversions and full refurbishments delivered with control not confusion.
Every home has potential waiting to be unlocked. The hard part is getting there without the stress. Many projects stall because nobody takes full control. Quotes change, trades vanish and deadlines drift.
That’s why we run every job from start to finish. Our home renovation in Sutton Coldfield service covers design, costing and building. You deal with one team and one clear plan.

Renovation Should Feel Structured, Not Stressful
Our design, manage and build approach keeps everything under one roof. No juggling separate contractors.
We don’t cut corners to win cheap jobs. As experienced renovation builders in Sutton Coldfield, we suit homeowners who value quality. From Four Oaks to Walmley and Boldmere, we treat every home with care.
First, we get to know your home and your habits. What frustrates you? What would you change? We turn those answers into a practical layout.
Period and post-war homes often hide tricky details. We inspect structure, drainage and access early. Issues are fixed before building starts.
You receive a detailed quote based on the final design. Each item is listed clearly. Nothing is added later without your say.
Before work begins, you get a full schedule. It shows each stage, every trade and the finish date. No guessing what happens next.
Our team runs the site and handles every detail. Materials, trades and checks are all managed for you. You simply move into your finished space.

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![]()

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.

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![]()
