Extension Builder in Merton Park
Hi there, I’m Neil, I’ve got 20+ years of experience in the construction industry. I’ve worked all over London and Greater London over the years and travelling to work is not an issue for me. I have an experienced group of people that I work with and who know how to get the job done on time and on budget. From the domestic side of the industry i.e. garden walls, extensions and new builds to the commercial side which includes retail units, office blocks and housing estates, there’s nothing that can’t be built!!! If an architect can draw it, we can build it!!! Thanks for checking out my profile and I look forward to hearing from you soon.

Being our first extension project and not knowing any builders we were very anxious about selecting the right people, M & N builders were clearly the best of the bunch! What impressed us was their enthusiasm for the work and the understanding of what we wanted. They are a very professional team who kept us well informed and are also very efficient and like to keep a tidy working environment! We absolutely love what they have done for us and would highly recommend M & N to anyone and will definitely use them again in the future. Thank you M & N for your professional service.
