Latest review:
We had a really positive experience with Joe and the team at Design Build Manage and would highly recommend them. From the outset, the quotation was excellent — very clear, detailed and easy to understand, with a full breakdown of the works and a sensible staged payment schedule. This gave us a lot of confidence going into what was a fairly substantial project. Joe was very hands-on throughout and was on site most days. Communication was always clear and responsive, and we always felt we knew what was happening and what the next stage of the project would be. The whole team were incredibly friendly and considerate, particularly as we were living at the property throughout the works with young children and a dog. They were always respectful of our home, tidy and genuinely pleasant to have around. The project did run a few weeks beyond the original schedule, but this was largely due to unforeseen circumstances that arose during the build, and we were kept informed throughout. Most importantly, we’re extremely happy with the finished work and the way the whole project was managed. I wouldn’t hesitate to recommend Joe and the Design Build Manage team for any building project, big or small.

Extensions- 24 Jun 2017
We had a large piece of work done by Johan and his team. It was a 4m single storey rear extension with new kitchen installation, converting the old kitchen into a downstairs bathroom and utility room, plus other bits and bobs like new boiler, rear patio. We got quotes from a few builders, Home Renovations weren't the cheapest, they were actually towards the higher end. But we went and saw their previous work and spoke to some of their other clients. The work was done to a high quality and the clients seemed to be happy so we decided to go with them. Johan's team are very hard working, professional and polite. Pawel and his team of builders, bricklayers, plumbers, electricians, etc. would turn up before 8am and finish at 6pm working solidly throughout the day. There is Magda as the project manager who keeps you in the loop, and answers any of your questions (which we had many). There is Michaela on the finance side who keeps you up to date with the budget. Our budget went over by 5% with "variations" (extra work or materials) but it was always communicated why and the work wasn't done without our approval. Pawel would give his recommendations but the final word would always be ours. But these things can add up. Overall we were very happy with the build, it was done to a very high standard. They also finished it before time. They said it would take 12 weeks in fact they finished it in 10 weeks which was amazing as you would normally expect these things to go over.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

What to ask a Forest Row extension builder before hiring?

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

An extension builder in Forest Row 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 Forest Row 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 Forest Row?

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