We had the pleasure of working with Alfa Style Limited on our loft conversion and we can recommend them highly and without reservation. Their work is incredible, attention to detail outstanding – our build was done with care and precision. They turned up on time every day, worked incredibly hard and quickly. In addition, they were extremely clean and tidy in the workplace – they never left the worksite in disarray. This is the first time we have done such a big project – Ruslan, Slava and their team were amazing. They were brilliant at explaining what was going to happen, day by day, week by week and translated the more technical information! No question or query was too much. The service after the build had finished has also been great, calls to check everything is OK and any queries we have, they are only a phone call away. We have had so many compliments from family and friends who have seen the finished build … it has made a huge difference to our house, we could not be happier.

Ahmad and the Beam Developers team did an amazing job on my rear extension. We were very particular with our requests and are generally picky people but they were very patient and accommodating to our every request. We were shown the drawings, made adjustments and managed to tailor the project exactly to what we wanted. The finished results were amazing. No big project for us soon but should we plan to do the loft will definitely use Ahmad and his team again.

What can I say about Christian and his father - Nicolas. They did an absolutely amazing job in our home. From the moment I spoke to him about the work to be done I knew I would hire him. He was professional from start to finish and did a stellar job on splitting a room into two and creating a hallway. Very pleased with every part of the work done and will most certainly use him again. Highly recommend.

What experience do you have with similar extensions in North Kensington?
