Carpentry- 18 Aug 2025
Dennis gave a good quote, answered any questions I had, was understanding when the door was delivered damaged and had to put the job back a week. He arrived on time, he was clean and tidy in his work and made easy work of fitting our wheelchair access bathroom door (3ft wide). We are very happy with the finished result and will definitely go back to him if we need a carpenter in the future.

Construction of new 4 bedroom house where RBA Builders Ltd was the lead contractor. Remigiusz led the team and was extremely reliable and professional at all times.

Decking- 7 Jun 2020
*****HIGHLY RECOMMENDED***** Firstly, these guys are lovely hardworking honest people who were only interested in making sure we got exactly what we wanted! Their work was nothing short of outstanding and I am absolutely over the moon with my decking. Considering my garden is on a slope I didn't think it would turn out as amazing as it did. But thanks to their skill, we now have a fabulous garden space to enjoy. They used only high quality materials and I have to say they are complete perfectionists. I am happy to be a reference for anyone who is thinking of hiring. 5* service, great price and one happy customer!!! Thank you!!!! Actually can't thank you enough!!!

Louis and team completed a front of house single story extension, installing 2 steal beams, making good and transformed our house. The workmanship was to a very high level and he came up with a few ideas which we added to the design. Louis is incredibly tidy and often goes further than any builder I’ve seen to keep the space safe and clean. We love our new space and cannot wait to put it to good use.

Extensions- 28 Jan 2026
Dan came round at short notice to discuss our plans for a garden room; he provided a very detailed itemised quote so we knew exactly what we would be paying for. Before committing we had multiple questions for Dan and he (very patiently!) provided clear and detailed answers. We set up a WhatsApp group with Dan and his communication with us throughout was brilliant. He kept us updated with the plan/schedule for each day, he sent us before and after pics to show progress and was always quick to respond in detail to any of our queries. We are really pleased with the finished build, it ran smoothly and it finished on time. We really appreciate Dan, Chris, Cam and Alfie's hard work and would certainly use them again for any future projects.

Kevin and his brother carried out a single storey extension to the rear of our property. The extension was built as per the drawings we supplied. He was happy to sort out any issues we came across and was very reliable and trustworthy, always turning up when he said he would and was very approachable and happy to explain things during the build. Would recommend for similar builds.

What to ask a Romsey extension builder before hiring?

Before hiring an extension builder in Romsey or extension building company in Romsey, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Romsey?

An extension builder in Romsey should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Romsey extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Romsey?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Romsey extension builder’s ability to deliver a result that meets your expectations.
