Conversions - General- 21 Mar 2026
Arturas and his team have done an outstanding job in a complex, full-flat renovation involving structural work, floor levelling, complete electrical rewire, complete re-plumbing including pumps and heater, full bathroom and kitchen fitting, basically everything. I honestly could not have hired a better builder. Quality: the team is exceptionally dedicated and diligent, following the design to the millimetre, reading every specification and installation instruction, being exceedingly careful to ensure everything is done at a high standard. The result speaks for itself - everyone who visited the flat is in awe about the quality of workmanship. Expertise: the team really knows what they are doing. There was nothing they can’t handle, and they found very smart solutions to every problem. They advised me at every step of the way, with patience and clarity. Honesty: Arturas, Vasyl and Vova are excellent people, honest to the bone, trustworthy and principled. In summary, top class builders.

Conversions - General- 2 Dec 2021
Samz Construction help me to finish installing an RSJ another building company started. After three months of living in a building site, they came in like the DIY SOS team, not only installed the RSJ but leveled the floor, put up a structural wall, and fixed a few other issues around the building in a week. Really pleased with the quality of work, everything easily passed building control and Sohail did an amazing job PM the work. It's difficult to find good reliable companies to work with and I have lost a lot of money by picking inexperienced builders, but I couldn't recommend this company and the team enough!!!

This was a major piece of work. F&G Design and Build created a stunning new storey to the house. The roof was renewed, new windows inserted back and front, plus a shower, toilet, cabinets and basin in adjoining bathroom. Special mention needs to be made of the extension to the stairway. They copied the original design to perfection (much admired by all those who have seen it). They also refurbished my kitchen to a very high and beautiful standard. They were always friendly and approachable and totally reliable. An absolutely brilliant team, and a pleasure to work with. And they finished the job on time!

Calvin and Jimmy have been absolutely brilliant, and have been the best builders that I have employed. So much so, that I have subsequently asked them to do a whole shopping list of things, from fitting a kitchen to removing an old fireplace. They are always on time, very polite, kind and knowledgeable. Best of all, they get things done quickly without any fuss. Calvin has been invaluable in sourcing items from trade required for the latest project, and clearly talks through requirements of any project. I would very happily recommend them for the excellent value they offer and fantastic level of workmanship.
