I had a commercial property converted into 2 one bedroom flats. Akam builders did an A-class job. The work was done to a very high standard and within the time scale stated by Gurwinder.

Piotr's work is really good. I did four or five kitchens with him and I did recommend him to him to another builder friend of mine and they are happy with his work - no complaints. He arrived on time so there were no delays. I too am very pleased with his work and would of course use him again when I have some stone work to be done.

My house was old and its condition was poor. Much were needed to be fix. The original kitchen layout were also inconvenience to my wife. I need to have all these changed under limited time. This builders have a team of specialists on almost every aspect. They gave me variety on the layout design and choose of materials.
