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.

Luke and your builder ltd done our back and side utility room. Even though we’ve had lockdown and COVID 19 they done a great job. I’ve used your builder ltd a few times and the quality of work is of the highest order. What they quoted before they started is what I paid. Couldn’t be happier with the end product. Completely transformed our house. Would highly recommend them.

Extensions- 1 Sep 2025
Ben, Ian and his team did a brilliant job. They came across a few issues this was due to the building plans they had to work from (architectural designer did a disappearing act). This didn’t faze them at all and kept me informed of how they would solve these concerns. They always arrived on time and constantly consulted with me as to how I wanted things to look. The whole extension consisting of a new kitchen and shower/toilet room couldn’t have turned out out any better. They have since completed a few other jobs one being a seating area (completed just from a picture I showed them) with cupboard storage. Again really pleased with the results. Pictures show during and after

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.

What to ask a Eastleigh extension builder before hiring?

Before hiring an extension builder in Eastleigh or extension building company in Eastleigh, 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 Eastleigh?

An extension builder in Eastleigh 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 Eastleigh 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 Eastleigh?

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 Eastleigh extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Eastleigh extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
