Restoration & Refurbishment- 3 Mar 2016
Paul has done the most incredible job on my listed cottage. He's passionate about the building, works to an extremely high standard and does what he says he is going to do, and more, without ever going over budget. Paul has completed a large amount of difficult structural work as well as fully re-fitting the kitchen and bathroom and I will be using him for much more work on the house in the future. I cannot recommend him highly enough.

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy
