Extensions, lofts, garage conversions and full refurbishments delivered with control not confusion.
Plenty of Solihull homes have the space. The trouble is how it’s laid out. Rooms that rarely get used, a kitchen tucked away at the back, and decor that hasn’t changed since the house was bought.
As a design and build home renovation builder in Solihull, we sort that out properly. We plan the changes with you, price them in full and run the build ourselves. You won’t be left coordinating trades or chasing anyone for answers.

Renovation Should Feel Structured, Not Stressful
A full renovation on a bigger house involves a lot of moving parts. We keep all of them under one roof.
Our clients want certainty more than a bargain. That’s the kind of work we do best as a Solihull renovation company.
We spend time in your home before drawing anything. Which rooms get used, which don't, and what the family will need in five years' time. The layout is built around those answers.
Opening up a larger home often means steels, new foundations or rerouted services. Our build team checks all of that at design stage, so the plans are ones we can actually deliver.
You'll get a full breakdown tied to the agreed design. Higher-spec finishes are priced separately, so you can decide where to spend and where to hold back.
We map out the whole job before starting, including delivery dates for kitchens, windows and joinery. A late order shouldn't hold up an entire build.
Your project manager is on site regularly and checks each stage as it's finished. We hand over a home that's ready to live in.
1. Home Extensions
Rear and wrap-around extensions that open up the ground floor and connect the house to the garden.
2. Loft Conversions
Extra bedrooms or a quiet office upstairs, often with an en-suite included.
3. Garage Conversions
Many Solihull homes have an integral garage that’s barely used. We turn it into a proper living space.
4. Full House Renovations
A complete home refurbishment in Solihull, covering structure, services, layout and finishes under one contract.
5. Kitchen Renovation
Kitchens designed as the centre of the home, with room to cook, eat and spend time together.
6. Bathroom Upgrade
Main bathrooms, en-suites and cloakrooms, finished to a high standard and built to last.

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![]()

Amazing work by Sunnie and the JMA team. Definitely worth the money and has added value to my house
It depends on the size of your home and the level of finish you’re after. Most of our projects start from around £30,000. You’ll get an itemised price after the site survey.
Internal changes usually won’t. Extensions, lofts and external alterations sometimes do, and part of Knowle sits within a conservation area. We check with Solihull Council and manage any application for you.
In most cases, yes. We plan the work in phases so the key rooms stay usable for as long as possible.
That depends on what’s involved. Once the design is agreed, you’ll get a written programme with dates for each stage.
Yes. We’ll guide you on flooring, tiles, kitchens, bathroom fittings and joinery, and explain how each choice affects cost and lead times. That way, your selections suit both the design and your budget, with no surprises once the work begins.
You don’t need a finished plan before getting in touch. Most people start with a list of what isn’t working and a rough idea of what they’d like instead.
We’ll visit your home, talk it through with you and point out what’s realistic. You’ll come away with a clear sense of cost, timing and the next step, with no obligation to go ahead.
