  • Wrap around, mostly double storey, extension

    Chris and his team built our double storey wrap-around extension which was completed in April 2021. It was a big job, he stuck to the quote and timeframe and we are so pleased with the end result! There were a few hiccups here and there (every build has them I’m sure!) but Chris dealt with them quickly and we were satisfied with how they were handled. We felt we were able to ask Chris and any of his team any questions as and when they came up. All the guys were very helpful and friendly and our neighbours commented that they all seemed hard working and how they had kept the site (and road outside) clean and tidy. We would definitely consider Chris and his team if we are in need of any building works in the future!

  • Large side and rear extension

    Chris was great throughout, gave best and clearest quote. Was willing to change spec within reason during the build and was really flexible fixing snags.

    I could not have chosen a better builder.

  • Kitchen extension and fit-out

    Our decision to go with Chris's CSN Building Contractors proved to be good one.
    We've ended up with the extension we wanted at a decent price and completed in an acceptable timescale.
    Chris's tradespeople were a hard working bunch and the quality of their work was good.
    General housekeeping of the site left a bit to be desired, however. My wife would have been much happier if there'd been a bit more tidying up at the end of each day and if accumulated waste material had been taken off site more frequently.
