    Highly recommend

    Posted 10 January

    I had my garage converted into a gymnasium and office space, John and his team were amazing, always professional and reliable. I had a lot of quotes but they were the cheapest and the work is to the highest standard, it turned out even better than what we had visioned thanks to the help and expertise of John. I would Highly recommended for anyone wanting any home improvements, conversions & extensions. You'll be in the best hands.

    Hardwood Flooring - Excellent Service

    Posted 05 January

    I had some hardwood flooring completed across my flat (quoted at and completed for £2000) as well as a new kitchen worktop (£500). The work was exemplary and I would 100% recommend.
