We had a kitchen extension designed by Jonathan Hughes at 3DR-architects, and he suggested to ask for a quotation from Gareth Cox (Key Choice Builders). Gareth came around very quickly, discussed the plans extensively and explained his way of working. Within a few days he provided a quotation and after advice from the architect, we decided to go ahead. We never had any regrets. The work comprised of an extension with a breakthrough to the existing kitchen, a porch, a front path, and a patio. Pre-fab Structural Insulation Panels were used instead of traditional inner walls and roof structure. Everything was done efficiently, some extra work was added during the project, but there was little delay. During the project, still a few design choices had to be made, but it worked out very well with good suggestions from Gareth and his team. Gareth and his team are very considerate and try to limit the burden of the building work on the home owners as much as possible. What was particularly appreciated is that Gareth makes a lot of effort to keep us informed on a daily basis and that he ensures that the results are in line with the home owner's wishes. He responds very quickly to issues and concerns, and has lots of suggestions for materials and providers. In conclusion, we are very pleased with the result and have no hesitation in recommending KeyChoice builders for similar building projects.
