Gjon and his son Julian did an amazing job tiling our kitchen floor. They were prompt in communications and completed the job within the agreed time. Left the job clean and tidy after themselves. Will probably hire them again to install a splashback later on in the project.

Michael was responsible for organising and overseeing my self build project, including the demolition of the old house and site preparation. The new detached house is approximately 5000 square ft over four floors including a basement. Michael's diligence, professionalism and reliability were exceptional. I have also used Michael on other small projects and have been equally impressed. Above all, i have found him very trustworthy. I would happily discuss the projects he has been involved with anyone considering offering Michael a project to carry out.

Extensions- 5 Nov 2016
Leslie carried out the following works: chemical damp injection to walls on rear extension, reroute down-pipe, repair fracture on rear wall, install gutter hedgehog. Hopefully, this will resolve some of the issues we had with damp, a blocked down-pipe and an overflowing gutter. Leslie arrived on time on the first day but was delayed a few hours the next day. However, the work still was done within two days as expected. Thank you!

Gerti completely renovated both of our bathrooms, and the final results were absolutely amazing—exactly what we wanted. He was extremely flexible, offered valuable advice for other aspects of our home, and consistently went above and beyond. Having done a lot of work on our house, we can confidently say he is the best builder we’ve worked with. His pricing was very reasonable, and we will definitely use him for future projects.

Extensions- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

Kitchen Fitting- 24 Oct 2016
Kris, Gustav and their team have been absolutely amazing, cannot praise them enough. First of all - the job ended up being a lot larger than initially thought- as decided to replace old ceilings and flooring, walls -everything was uneven to start with. So took everything back to 'bare bones' and pretty much built it up again as a new house. New electrics, water pipes, completely new kitchen and bathroom. I really appreciate they were very straightforward with the estimated costs from the beginning - it did run slightly over budget but nothing too bad as had some contingency funds prepared. I would have hated to be quoted one price then half way through the project to discover it escalates out of control. Thankfully they are really honest and reliable. They were always easy to reach and replied any question I might have had in a timely manner. This was particularly important to me as I was between uk and us at the time so couln't be 'looking over their shoulder' so to speak. Last but not least the finish and quality of works is absolutely amazing! They couldn't have paid more attention to every little detail if it was their own home. For instance I remember last day of work when they were tidying up Gustav came back to put up door stoppers for me, completely on his own initiative. It's just a little touch but goes to show the dedication they've put into the project and care about the finished product.
