Groundwork & Foundations- 30 Aug 2022
Axel & his team have done a huge amount of work for us through 2022. They started by building the foundations, and then also built the block walls and the structure for the roof. They also constructed an entire extra timber framed shed. After more than four months of working for me constantly I can say that I'm very happy with the quality and speed of Axel's work. He has worked through all the work we have given him, and all the extra issues that came up, with a pragmatic and competent approach. The site today is unrecognisable from when he arrived (he also removed several tonnes of soil for us etc), and I would hire him again without reservation.

Landscaping- 3 Jun 2021
On our first meeting I felt comfortable and was glad of input from Robin. Agreed to a plan and only had to wait a few weeks before work could start. All preparations made to protect my drive before skip arrived. All work carried out in a very professional manner and team were very polite and friendly. Even though weather was against ground works they provided shelter so work could continue. I’ve been very pleased with their approach and can’t fault the outcome. Although met with a couple of delays on garden furniture, (nothing to do with Robin and his team, circumstances outside control)all other aspects of this job have met with my approval. Was apprehensive of having people in but can honestly say there have not been any issues and when the skip was removed within an hour, Robin was back on site to clear and wash down the drive. So looking as good as new. It’s been a pleasure having them on my property and will look at using their services again in the future should the need arise. Nothing too much bother. So my thanks to them all.
