Extensions- 8 Oct 2018
Alban completed a lateral kitchen extension for me in west London. Very happy with the results and to add my name to others that have given 100% positive feedback. What I particularly liked - (1) Alban took great care to protect the rest of my house while working (protection, covers etc), (2) his team were friendly and polite to neighbours. Building works are always noisy and disruptive, they kept others 'on side' and (3) they worked to the timing and schedule agreed (4) they cleaned up, every single day (5) they worked to a high standard and corrected for any issues, despite my inevitable last minute changes. Wish him and team best success... happy to recommend. Rob

Conversions - General- 9 Dec 2016
Andrei and his team did an amazing job with my house. They refurbished it to the minutest detail, and made sure everything was executed as requested. They worked consistently and efficiently for 4 1/2 months, in order to deliver. They started around the second week of April, and I was able to move in on the 3rd of August. They did wiring, pipping and flooring. They knocked off a wall to create an open plan lounge/dining area. They removed chimneys to make more space, and re-plastered and re-painted the whole house. I am very happy with my new home and I am already thinking of hiring Andrei and his team to convert the loft. Working with Andrei was a pleasure. During the last month, I was in touch with him everyday and would visit the property 2 or 3 times a week, to check on updates and see how things were being done. It is very difficult to find trustworthy builders, but Tudor Constructions are professional and always happy to listen to their clients. I would definitely recommend Tudor Constructions.

Restoration & Refurbishment- 18 May 2026
William and his team did a great job of redecorating our 4 bed period property inside and out. William gave a detailed quote which enabled us to select or deselect some items and know the relevant cost. There were some minor snags that required extra plastering and repointing all handled with ease and no fuss. The communications were good and the team were hard working and courteous. I would not hesitate to use William again.

Extensions- 4 Aug 2020
On a cold November evening, Tony and his team turned up to provide a quote and within a week this was received. The quoted price came in the middle of the pile, which was a good start and aligned closely to the ballpark figure I'd received from a friend who was also in the trade. We then visited a site they were finishing off, and Tony had the confidence to ask us to speak to the client without him there and they gave us the confidence to proceed. They started in January 2020 and rapidly moved through the works and engaged closely with my architect, Structural engineer and building control and proceeded based on their recommendations strictly. We lived in the property as build progressed and the team ensured that the site was secure every evening and we were safe. As COVID-19 hit and we went into Lockdown, the team continued to come and work (we were separated from them as the house was boarded up) and the only challenge was getting supplies. Tony scoured all over London, picking up items as best as he could and work continued. Once they'd broken through into the old part of the house they continued to progress rapidly and showed utter professionalism. The team lead's attention to detail is impressive, and he gave great recommendations on what would be the right approach when we were laying out features such as window sizing and lighting. The standard of work is excellent and I would highly recommend them.

Extensions- 5 Sep 2019
One of the best builders I have ever worked with. PMB take great pride in the work they do and finish to a exceptional level (even better than a lot of premium and expensive builders in the industry). Colin's knowledge about all aspects of building work is unmatched and that shows in the end product that he and his team delivered for me. PMB did a full refurbishment & substantial extension (everything knocked down except 3 external walls) - ground floor ext, first floor ext, loft extension, full re-wire, plumbing, gas, UFH, walls, plastering, fitting, decorating etc. His prices are reasonable and he advised when unexpected costs come up so I could make a decision on what to do. I will definitely use him again.

I originally contacted Joe from Orama to fit a new kitchen for me. When he came to give me a quote, I hadn't yet chosen what I wanted. He really took the time to make several recommendations and so I decided to go ahead with him to design my kitchen fully and fit it. The team were so easy to work with and most importantly respectful in my home! Their attention to detail is second to none. He really understood the style I liked in one conversation. The finish is flawless. I highly recommend them!!
