Hard Flooring- 21 Sep 2021
Very pleased with the service provided by Nick . Our hard wood flooring in dining area was badly damaged but it was replaced and restored very professionally to its original glory. He is very nice, polite person and very easy to communicate. He is an excellent carpenter and if needed I will use his service again.

Landscaping- 16 May 2026
Very professional quotation, I chose over two others because he was very clear on where extra costs may arise and was very straightforward. He advised a different finish than I originally thought I wanted with cut stone edges and it looks even better with his suggestions. His crew were very friendly and professional. Would definitely work with him again in the future.

Extensions- 29 Jan 2015
PM Building epitomise what a modern day, professional building firm should aspire to be. Transparent pricing, a friendly team working 6, sometimes 7 days a week to get the job done quickly, an eye for detail and very high standard of final finish. All comms and the overall work is run through Bart, who answers to phone, text or email quickly and frequently outside normal working hours. This is ideal if you work during the day and cannot be around to oversee things directly. We also got PM Building to make us a bespoke kitchen, again very high quality and millimetre perfect. If I had to find some negatives, they are not the cheapest company you could find, but there again you get what you pay for; also, we developed a few issues with some retaining walls in the garden, however, they returned when I contacted them long after the work had finished and fixed them! All in all, an excellent, honest and professional company to deal with. I would, and have, recommended them to friends...nuff said.

Extensions- 10 Jun 2020
We had a one bedroom lower ground floor garden flat and did a side return and extension into the garden. The flat is in West Kensington area. We also did a full internal refurbishment and moved just about every wall, moved boiler, new Porcellanosa bathroom, new kitchen, new flooring throughout, a large bi-fold door in the living room to the garden. Chris and RAS Construction have been the best possible builders for this project. They were simply amazing. What we loved most about them: - speedy and no-nonsense communication (very important for us) - friendly and approachable - super professional and friendly team - very quick and helpful when a problem arose due to some architect's error - good aftercare - stayed in quoted budget - offered improvements and reasonable quotes - very easy to work with - only asked for partial payment every few weeks after job had moved along reflecting the amount charged This review was written about 8 months after the project was completed and we are still very happy with the quality. I would not hesitate to recommend Chris and his team at anytime. You hear so much about bad builders, we have been very lucky that we have found him. We are now house hunting for a bigger place and will re-engage with them for the next project.
