Conversions - General- 22 Jun 2026
Bled from BSM was fantastic from the start of the job to the finish. His pricing was fair, and he turned up each day on time, and left everything tidy each day. Nothing was too much effort, and the quality of the work was outstanding. I would have no hesitation in recommending him to anyone else.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

Bricklaying- 19 Nov 2025
Please avoid this company for many reasons. There work is absolutely shocking and the owner is incompetent and should be ashamed of himself how he left my job. I’ve tried to contact Elijah and he’s blocked me, he’s an absolute disgrace. I will put up pictures of his work so you can see how bad his work is.

Bricklaying- 28 Jan 2025
I recently hired A1&PM to carry out structural repairs on my house, including replacing window lintels and providing complex temporary works to support the structure during the repairs. They also patched plaster, skimmed a wall, rendered, and repointed an external wall. From start to finish, the team was professional and reliable, turning up on time with all the necessary tools and materials. Protecting carpets and covering furniture. Their knowledge and expertise were evident throughout, and they completed the work exactly as promised. The pricing was very competitive, and the quality of the work exceeded my expectations. I was initially sceptical due to some past review, but my experience couldn't have been better. I would definitely use their services again and wouldn't hesitate to recommend them to others. Fantastic work—thank you!

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.

Bathroom Fitting- 7 Jun 2026
We recently had our bathrooms refurbished by Vasile and his team, and we are absolutely delighted with the results. From the very beginning, they were professional, reliable, kind, and exceptionally helpful. Vasile was always available to discuss every aspect of the project, taking the time to explain things clearly and answer our questions with patience and honesty. It felt as though we had a genuine partner supporting us through the renovation of our three-bedroom flat. Vasile and his team were fully invested in achieving the best possible outcome and were always willing to go the extra mile when challenges arose. The quality of their work is outstanding. They worked efficiently, kept us informed throughout, and ensured everything was completed in a timely manner without compromising on quality. We would wholeheartedly recommend Vasile and his team to anyone looking for skilled, trustworthy, and genuinely caring professionals.

Painting & Decorating- 1 Jul 2017
I would highly recommend these guys. They did a very high quality job decorating my lounge, dining room, hallway and stairs. They started the job on time, worked through the weekend to get the job finished in good time, left the place clean and tidy at the end of every day, and cleaned up immaculately at the end of the job. The price was also very competitive compared with other quotes I received. I hope they are available again in a few months time when I have more decorating that needs to be done.

What experience do you have with similar extensions in Barbican?
