Extension Builder in Bloomsbury
I started working in construction sites as cleaner back in 2005 and then joined a company that was carrying out commercial renovation for licenced premises, listed buildings and offices and then moved to other companies that were carrying out domestic works, such as loft conversions, extension, renovation and everything in between. I would like to think of our company as a 1 stop shop to all your construction needs, from planning to costing, from project managing to building and delivering.

Rating: 4.5 out of 5

We are a southwest London Based loft and kitchen extension specialist.

With over 15 years experience in this area we know inside and out how these properties were built so when it comes to structural alterations you couldn't be in safer hands.

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

I was very pleased with this company so much so that they are starting a new job for me November 15. The building firms carried out a full loft conversion for me installing bathroom, brickwork, joinery, plastering, Roofing and installation of windows and double glazed doors. I have high standards and want everything to be completed in the same way, the workmen respected my home and always left if clean. My main contact was with the owner of the company Dwight Lynch, he was very flexible and Nothing was too much for him to do. He has an attitude which I like in a builder "customer not always right but must be happy" he provided me with ideas along the way and where things did not go to plan due to my own instructions he worked around the issue and provided suitable alternative options. I was very happy with the pricing of the job and feel that certainly I would recommend him and also I would use him again. He and his workmen were all trust worthy and I gave them keys to my house to carry-out work whilst I went on holiday. I had no concerns when I came back everything was as I left it.

What experience do you have with similar extensions in Bloomsbury?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Bloomsbury extension builder’s ability to deliver a result that meets your expectations.
