We used this company before and decided to go with them to plan and construct our wrap around extension. I can't thank the uma design team enough for getting the plans through and quality of build, it really has changed the house drastically. We didn't think we'd have so much space from the small house we had, and the modern touches such as the skylights are a great touch! It took a little longer than scheduled, but we were happy to wait for the quality of finish. More...

Needed an extension built and they helped me out alot with building regs and drainage. Gave me structural cals at a reasonable price and the extension compared to some other quotes i received. They had friendly builders which carried out the work to the plans and within timings. More...

Very happy with the drawings and construction for my extension, completed to a good standard within the time schedule. Communicated throughout the project to any details to be smoothed out. Good value for the service, the UMA team paid close attention to what I wanted and resolved concerns during the build. More...

They helped us with our planning process and construction, and we had a beautiful extension built last year. A friendly and kind team, sensitive to our budget and time, we got some great ideas from them. Thanks again!

Had Uma build a garden room a while back- here's my feedback!
From start to finish we received a great service contacting them online and over the phone- the whole process was transparent.
The building team was professional, attentive to details, and were very friendly in taking on board my feedback during the build (A couple of small issues with the door, but these were dealt with quickly). They also gave us some useful tips to maintain and decorate my garden pod.
I've only needed a small radiator in the room for during the winter, but it's really been a great place for me to work from. All in all outstanding transparent service, good materials, smooth install, still a great space after a couple of years. I can highly recommend this company.

I had a shed/pod fitted last year between lock downs to enable me to work from home. it has been a total life saver. Also, really boosted my mental health not sitting in the house interrupting everyone. The fitting process was great. The guys were very kind on working hours and not making any mess. The shed is well built and with a small electric radiator is cosy in winter. Can't recommend enough. So a few points of learning a few months on... - the shed itself is a bit taller in real life than I'd anticipated - whilst in most cases this won't be a problem in terms of planning, its worth checking. - there isn't a vent so worth investing in plants and mini dehumidifier to keep the air purified - esp if you'll have a heater on a lot - do as I did and get some extra sockets added. Never have too many plug holes! I've recommended these guys to so many people.... excellent. More...

Just wanted to review the work from UMA , it's exactly what we were looking for. Was altered when needed as we had an irregular space but looks great, Thanks for your hard work and attention to detail.

Fantastic service, everything was on time and Michael was so helpful in making changes to the plans when the building control officer asked. We are really pleased with the extension and are enjoying this space very much. The builders you recommended did any excellent job, even with the delivery problems cause by lockdown, thank you for your hard work, we've recommended you to all our friends! More...
