I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

Valentin was fantastic. He was efficient and professional. He did a fantastic job and even cleaned up after the job. He was polite, friendly and knew exactly what he was doing. I will definitely be getting more work done by him and have even sent him to my parents house today after finishing my job, to get quotes for other work. Thank you for helping me out today. Much appreciated

Stefan did an extension for my flat from the installation of structural steel, to the roof, and demolition. To building the shell and all cosmetic work inside. I am very happy with the work. Time keeping was good, pricing was good he was open and honest throughout, he was very tolerant and easy to work with. Always positive and willing to help if there were any issues. He would help resolve any issues in the quickest and best way possible. Very happy. I would happily recommend him.

Groundwork & Foundations- 18 Dec 2020
Had three quotes for a base for a garden shed, Toma was the cheapest by far. We arranged a day for the work to be done, bit apprehensive because I never knew anything about the company. Mr Toma and two others turned up, what lovely people they were, especially Mr Toma, the job was highly professional, everything was tidied up. Would I use them again.........100%. I would highly recommend them.

Decking- 29 May 2020
Started on time and completed the decking extension & renovation to a high standard. Ensured that small details like cuts around poles etc, were finished properly and not left with gaps. Next time I would confirm that clearing rubbish is part of the quote, but highly recommend Przemek for quality finish.

Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.
