I am pleased with and grateful for their work on my flat refurbishment. From site survey, design and build, to final finishing touch, they helped me throughout the project. They were really professional and did not compromise on the quality of their job. Not only they were willing to accommodate my many special requests, sometimes change of plan at the last minute, but they were not shy away from making practical suggestions, which all proved to be invaluable. I guess for most home owners building projects are painful process, but oddly for me this has been an enjoyable journey thanks their great team.
