Posted on Google Stefan EngelsTrustindex verifies that the original source of the review is Google. Stefan and his team built us a beautiful single-storey extension, and we couldn't be happier with the result. The whole project went smoothly from start to finish (on time), and due to the clear communications we always knew where the project was at and what the next steps were going to be. We've already been recommending Stefan's Building to all our friends! Stefan E.Posted on Google Sam D'ArcyTrustindex verifies that the original source of the review is Google. If you are looking for a builder in Cambridge, look no further! Stefan helped us complete our extension project on our house and we could not be happier with the result. Thank youPosted on Google Thomas MartyTrustindex verifies that the original source of the review is Google. From our first meeting, Stefan was someone I knew I could trust to do a good job. He was knowledgable, experienced and good value for money. It was a garage conversion into two offices. He and his workers were always punctual, respectful and great workers. He provided regular updates and encouraged us to ask as many questions as came up. He provided answers and I never had cause to worry or complain. The job was completed before time and has an excellent finish. I would recommend Stefan to all.Posted on Google Chris JonesTrustindex verifies that the original source of the review is Google. Really pleased with our building work from Stefan and the team. The whole project ran like clock work and was great to have it completed ahead of schedule. Thank you and would recommend to my friends.Posted on Google Fabio LiberanteTrustindex verifies that the original source of the review is Google. Stefan built a single-storey extension across the back of our house with a pitched tiled roof, vaulted ceiling and Velux windows, as well as removing internal walls and installing three steel beams. From start to finish, his knowledge and professionalism gave us confidence in what is a major structural project. He kept us informed throughout and was very proactive with building control, making sure inspections and sign-offs happened at the right time. He’s excellent at working through challenges and finding practical solutions — always keeping things moving, but never cutting corners or rushing work. We lived in the house during the build, and Stefan was considerate, tidy and mindful of the disruption, which made a difficult period much easier to manage. The end result is a beautiful open family space that has completely transformed how we use our home. Most importantly, we feel very confident in the quality and structural integrity of the work. We wouldn’t hesitate to recommend Stefan to anyone planning building or renovation work.Posted on Google Khin Swe MyintTrustindex verifies that the original source of the review is Google. Stefan has done a fantastic building work for our recent garage conversion. He has a great wealth of knowledge and skill. All carried out to a high standard and in a short space of time. Highly recommended.Posted on Google Lena MTrustindex verifies that the original source of the review is Google. Stefan is a hard working and skilled builder. Our project was a garage conversion to create a little room with an en-suite. He showed flexibility and understanding when we added a few things and requested some extras and did everything he could to ensure that in the end we had what we envisaged. He cares for his work and takes pride in his professionalism. Stefan and his subcontractors are reliable, always show up exactly on time and will work weekends if needed - this degree of commitment can be rare in this business. He also communicates with customers informing them about timings and jobs and manages his projects with dedication. Recommended builder.Posted on Google S VTrustindex verifies that the original source of the review is Google.
