House Extension
Job completed on schedule and on budget. What more can you ask? We have been back in our house for two months after a major renovation and are completely delighted with the general workmanship and quality. There have inevitably been other contractors on site (kitchen fitter and renewable energy supplier) and Daniel and his team have collaborated seamlessly with them. There have been a few trivial issues since we have moved in that have needed to be addressed and these have been dealt with in a prompt and unquestioning manner. We can fully recommend BCS.
Julian, London
Daniel and his team completed a new-build house for us in 2022. We are now enjoying living in the beautiful, stylish home that he created. He was always reliable, efficient and highly professional throughout the build process and beyond. We were impressed by the quality of his work and the conscientiousness of his team, who consistently worked to a high standard. Daniel is an excellent communicator and was always able to resolve issues and find solutions quickly and effectively. We would highly recommend him.
