We hired this builder for a 2-metre rear extension and a very large garage extension and we’re really happy with the result. The project needed a pile foundation which is a bit more complicated, but they handled everything very professionally. They listened to what we wanted and kept us informed at every stage, which really helped as we were living in the house while the work was being done. The team were friendly, easy to deal with and worked to a good standard. Overall a very good experience and we would happily recommend them.

Kitchen Fitting- 31 Jul 2019
To say Nick is just a kitchen fitter isn’t doing his work justice, he’s a fantastic project manager and craftsmen as well. When we first met Nick he took 2 hours of his time running through all the options which was when we realised we were actually quite clueless! Although we hadn’t hired him at this point his advice was invaluable. We assumed this would mean Nick’s professionalism would mean he would be very expensive, this was not the case and he was actually a little cheaper than the other parties who quoted. Once Nick started it became apparent that he and his assistant Chow to great pride in their work and worked hard to get the job finished as quickly as possible to the highest standard. They left the site spotless at the end of each day. The result is a fantastic kitchen and flooring which we are extremely happy with. We are already thinking about the next renovation piece in our home and would love to use Nick again. Thanks Nick! Niall & Hannah

The job was a complete refurbishment of a one bed flat, including rewiring and re-plumbing. We would recommend Al and his team without any hesitation. From the very beginning and all the way to completion, we felt very lucky and fortunate to hire them. We found them to be very hardworking, conscientious and professional. The job was a difficult and complex one, but the team still completed within time and within budget. Al's advice made the whole process easier and we found him to be very trustworthy and honest. The end result was better than we originally hoped for and was done to a high standard.

Extensions- 30 Nov 2020
A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

Bathroom Fitting- 25 Feb 2022
This was the best experience I have ever had with a team of builders. Aldo and Leo were polite, organised and their workmanship is of a very high standard. They replaced the bathroom in our rental flat, and it looks really smart. They also refurbished the kitchen, replacing flooring and decorated the whole flat. We have just shown it to an estate agent as we are planning to sell it and they were very impressed. Aldo was very helpful in making suggestions of small changes that would save us money and delivered the project on time and right on budget. Would recommend them and will certainly use them again.

Tiling- 16 Feb 2026
Luis did an excellent job on my bathroom. He had to do a lot of prep work before starting the tiling, including rebuilding the floor and repairing the walls. At every stage he explained what needed to be done, ensured that I wanted to go ahead, listed the materials that would be needed, and the cost. It made a huge different to me that Luis was willing to source and purchase all materials; he checked in with me from the suppliers as to choice and cost, and sent receipts for every penny. I cannot recommend him highly enough, for his knowledge and expertise, his honesty and hard work, and also for being such a lovely person, nothing is too much trouble. I am delighted with my new bathroom, and am planning more home improvements with Luis, when he is free again!

What experience do you have with similar extensions in Whitechapel?
