Extensions, lofts, garage conversions and full refurbishments delivered with control — not confusion.
At J M A Group, we manage new builds in Birmingham with the same discipline used on commercial 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 Birmingham 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 Birmingham, 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
