Bathroom Fitting- 7 Aug 2023
We asked Richard to remove our old bathroom suite and replace it with an ensuite shower (not a wet room). Richard listened to what we were looking for in our ‘dream’ shower room and gave suggestions on layout, design and tile styles and colour ways. He has a good eye for Co-ordination and made some great suggestions for wall tile and flooring ideas. Shower installed was of a high specification and is fabulous! Extractor fan and ceiling lights also installed. Richard is a hard working craftsman who does the job to a good standard. As with any construction work there was some disruption but Richard took our two cats into account when going in and out of our property. Yes it did get dusty but what can you expect when building works happen?! Richard finished the job and left our ‘site’ in a very clean state with all building materials removed. We’ve asked Richard to come back and renovate our downstairs cloakroom next. Highly recommend!

I chose Baladine because it is a small local company and has experience and knowledge of this area. The bungalow renovation has taken over a year to complete and inevitably there have been challenges along the way, which have been overcome on both sides with patience, humour and co-operation. I found the trades people skilled and efficient and would work with them again. Overall it has been an interesting experience and I would have no hesitation in recommending them or working with them again on future projects.

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.

Bricklaying- 8 Jun 2026
Nathan and his son turned up on the agreed day. They let me know that they were going to start a bit later due to collecting materials. So great communication. Gave them a key to the garage, so that they could leave their tools and materials in a safe place overnight. They were very courteous and a joy to have around. Despite the bad weather they completed the upgrade to the front garden wall in the quoted time frame, and on budget. Would highly recommended them.

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.

An extension builder in Basingstoke 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.

What experience do you have with similar extensions in Basingstoke?
