Extensions- 1 Jun 2022
We are absolutely thrilled with our extension. Elliot and the team completed all elements of the project, which included numerous steels to replace existing supporting walls and the re-fit of our existing kitchen +new kitchen fit out. The work is finished to a very high quality and far exceeded our expectations. Product selections such as doors, windows and tiles were proposed by Elliot and were exactly what we wanted. Elliot and the team were professional and a pleasure to work with and we would highly recommend them.

Bradley worked on my house extension doing all the brickwork professionally with high quality workmanship. Upon completion I asked Bradley to stay on independently and lay my patio with surrounding brickwork. Again a superb professional job.

Conversions - General- 6 Feb 2023
Sorry this is long: our experience differs to most on here. We chose Better Living to do our side and rear extensions from start to finish. All was good until the subcontractors finished the main structures, then it all went downhill. Ben rarely answered his phone, texts, emails etc., and because they had started a bigger project elsewhere they repeatedly abandoned ours, often for weeks at a time. Even when we went on holiday, they had the complete run of the house for two weeks but did very little. Ben deliberately held up work for two weeks after receiving a stage payment a day late, having given us one day to pay after emailing an invoice. Beyond the main structural jobs their work was often sub-standard and our instructions were not followed due to poor communication between the team. Out of frustration we eventually took a lot of work off them and drafted in other tradesmen to complete the project, also doing some of the work ourselves. We have since had to have some of their heating work rectified by engineers. Not saying everything was bad, but fact is the list of problems and poorly completed jobs is too long to list here. They finished at our property over three months ago and have still not sent us the completion documents. As usual, Ben is not responding to our attempts to contact him. Despite being hospitable to their team, we feel we were treated shabbily by BL and sadly would not recommend them.

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.

Extensions- 8 Oct 2025
Jason and his team have just completed our wraparound extension, and the result has exceeded all expectations. Their workmanship, accuracy, and attention to detail are outstanding, and the whole process was smooth and stress-free. They stuck to timings, kept the budget in mind, and made everything feel effortless. Partway through the build, Jason had to undergo an operation and was signed off for five weeks. Remarkably, nothing was delayed — his team carried the project seamlessly, and with Jason still on site when he was able to be, everything ran perfectly. It’s a real credit to how capable they all are and the consistently high standards they work to. The only negative thing I can say is that we were sad to see them leave – they’ve been such a positive part of our daily lives over the past eight weeks. The finish is exceptional and we’re absolutely over the moon. We couldn’t recommend Jason and his team highly enough.

What experience do you have with similar extensions in Farnham?

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