We're very pleased with the work Brendan did for us.

Extensions- 13 Apr 2024
I had a lot of work done inside the house, installing a kitchen and bathroom including the plumbing and electrics, knocking down walls and changing the layout of the rooms.The work took a lot longer than expected but was completed to a high standard. We had to wait a long time for windows which held everything up and was beyond the control of Martyn or the team.The team were professional and knowledgeable and respectful of us having to live in the house meanwhile.

Loft Conversion- 12 Dec 2017
Mark and Will did an amazing job. They communicate well throughout and tried their very best to not disrupt the house. Though this sort of work is major and takes a lot of time it was a pleasure to have them around. They are always cheerful and I was happy for them to have access to the house to work while I was away at work. Top job, I highly recommend them.

Extensions- 26 Apr 2019
Mark and team did a really good job on what turned out to be a tricky build. We didn’t have a side return in the end but we did have significant building work carried out with the removal of a load bearing wall and placing of RSJs. Mark was willing to work with us and let us carry out some of the work and be flexible which was helpful. There were some communication difficulties at times, but we always worked through them and we are happy with the end result.

Bricklaying- 19 Feb 2024
I am very pleased with the quality of work that Lee did at my house. Lee is clearly very experienced and knowledgeable about building work. He replaced a cracked wooden lintel above a window and a patch of ceiling which had been removed. He showed me the new lintels after they were in place and how he had stabilized the wall above it. He put up new insulation backed plasterboard and replastered the whole area. He protected the window, window sill, floor and furniture whilst the work was going on and left the room very clean and tidy afterwards. I have no hesitation in recommending Lee for building work.

Extensions- 21 Oct 2025
Dan and his team did an amazing job of our single story extension. Dan provided a very comprehensive breakdown of his quote, which he stuck to throughout the build. We made a few changes as we went along and Dan accommodated these without hassle. The timescales were a little longer than planned, but this was due to the weather and other factors outside of control. Overall Dan provided us with a very competitive quote and met all our expectations in terms of quality and finish. We would have no hesitation in recommending Dan, and in fact we have done already to 2 of our friends :-)

An extension builder in Bristol 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 Bristol 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 Bristol?

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

How long will the extension take to complete?
