  • Double extension to rear of Victorian property

  • Extension to back and side of house

    After talking with many companies we settled on Mayfair as we had heard good things about the company and they even took us to a job that was nearly complete for us to see the quality of work.
    The company helped us with plans and advised us on many aspects.
    Our extension is half way through being finished now, we found the process easier than we thought, mayfair have been professional, tidy, respectful and communicated with us as much as possible.
    the job is ahead of schedule and looking great, I will post some pictures of the end product in a few weeks.
    Thanks to phil and all the lads for putting up with me.
    we will recommend you to friends and family and as discussed will use you for works on our other properties in the future.
