Before you think about moving, take a fresh look at your garage. It’s often a practical route to an extra room. The structure is already there, ready to be upgraded.

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![]()

Often not, as many are covered by permitted development. Planning conditions or conservation areas can change this. We’ll check your property with City of Wolverhampton Council.
Typically, we infill the door opening, upgrade the floor and insulate the walls and ceiling. Then we add electrics, heating, windows and finishes. Each stage is inspected along the way.
Yes, in many cases. Detached garages can make good offices, studios or gyms. Planning rules can differ, so we’ll check before designing.
Yes. The room must meet standards for insulation, ventilation, fire safety and moisture. We handle the details and coordinate building control inspections.
Yes. We can keep a storage area at the front for bikes and tools. The rest becomes a warm, usable room.
A converted garage can give you the room you need without a move. Picture a home office, a guest bedroom or a playroom for the kids.
