Latest review:
We hired Belle Partnership for a two storey extension and remodel of our home. The project included structural work (knocking through and installing steel beams), building the extension shell, roofing, new windows and doors, first and second fix electrics, plumbing and plastering. Communication was clear and professional from the start with any variations - either at our request or where small snags were encountered, which was inevitable on a project of this size - discussed and priced transparently before work proceeded which helped us keep control of the budget. The team were punctual and generally kept to the agreed programme. There were a few delays due to material lead times and weather, but these were communicated in advance and didn’t feel avoidable. We were kept informed of progress throughout, which made the process less stressful. Tidiness on site was good with the team keeping the working areas as organised as possible and cleared away debris regularly. We're very happy with the workmanship, the work being finished to a high standard. This was a significant undertaking for us and Belle Partnership helped us achieve what we wanted. Chris and his team were professional, approachable, and capable of delivering a substantial extension and remodel to a good standard. I don't think any project of this scale is entirely without minor issues but we felt they dealt with challenges responsibly and delivered what was agreed. We would recommend them to other homeowners considering a similar project.

RMD Replaced three bathrooms, cloak, en-suite and family. The work was planned so that disruption was kept to a minimum and we were give practical advice throughout as we made the detailed decisions during fitting. The work, including cabinet making, was excellent and carried out with an eye for detail. Alex has a 'belt and braces' approach so everything was fitted to last even if it required additional work and preparation. It was all done to budget too and the pricing was fair, open and honest. RMD proved to be great quality, trustworthy, a pleasure to work with and we wouldn't hesitate to recommend them.

I hired this company for multiple projects around my house, including a downstairs toilet, upstairs bathroom, hallways, media walls, and spotlights. I’m extremely happy with the quality of work and the overall service. I kept bringing them back for more jobs, which says it all.

Windows & Doors (Wooden)- 11 Mar 2026
Exceptional work and attention to detail. The scope grew way beyond the original task and I couldn’t be happier. The quality of the triple glazed windows that Mariusz sourced have unfortunately made me into a bit of a window snob though. I constantly have to restrain myself from commenting on other people’s inferior windows

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

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.

Do you offer a guarantee for your work? Most Farnham 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.
