Yes. Our design and build packages include everything from architectural drawings and planning permission to construction and final finishes. This means you only need one point of contact throughout the entire process.
Building a new home is exciting. But it can quickly go wrong.
Delays creep in. Costs spiral out of control. Decisions get made too late.
At J M A Group, we manage new builds in Finham with the same structured discipline used on major commercial construction projects. Every budget is built from honest, real figures. Every programme has clear milestones. And one dedicated, experienced team manages everything from the very first feasibility call all the way through to handover.
Dreaming of building your family home in Finham? We’ll guide you through every single step. Developing a plot for sale? We’ll deliver the quality and finish this area commands. You’ll have full clarity throughout. A genuine budget. A realistic timeline. And a team you can actually rely on.
We start with a thorough feasibility and planning review. Every aspect of the site, the design, and the construction programme is examined in detail before work begins. We identify potential problems early. We deal with them early. And we build a programme that keeps the whole project running efficiently from start to finish.
Here’s what our clients get when they work with us:
We don’t rush. We don’t cut corners. We don’t chase volume.
We plan carefully, manage thoroughly, and build with genuine pride.
Finham deserves that level of care. And that’s exactly what we bring.
Before anything moves forward, we assess the site, planning constraints, and construction challenges to ensure the project is viable — technically and financially.
We coordinate design development, approvals, specifications, and construction methodology so the build starts properly — not reactively.
Budgets are built around real market rates and procurement planning. Materials, labour, and lead times are aligned to avoid delays and cost escalation.
A detailed construction programme is created, sequencing every stage of the build to maximise efficiency and reduce downtime.
We manage the build end-to-end — trades, quality control, health & safety, and timelines — delivering a finished home or development without last-minute firefighting.
If you’re building your own home and want the result to be well planned, properly costed, and professionally delivered — without having to manage multiple contractors yourself — this service is designed for you.
We provide structure, guidance, and full project control, helping you avoid common self-build pitfalls such as budget overruns, poor sequencing, and design decisions that don’t work on site.
For developers who require certainty across cost, programme, and quality, we deliver disciplined project management from feasibility through to completion.
Our approach reduces risk, improves build efficiency, and ensures developments are delivered to a standard that supports resale value, compliance, and long-term performance.
If you own land and want to maximise its potential, we provide informed planning, feasibility insight, and structured delivery to help turn opportunity into a viable, well-executed project.
From early buildability assessments to full delivery management, we ensure decisions are made with both commercial and practical outcomes in mind.
