  • "Fast, honest and professional"

    Ben and his team have effectively carried out a full renovation of our Victorian maisonette, including a loft conversion. These are the nicest and most approachable builders you will meet, and will always take time to listen to what you need. Ben has a creative eye and will always suggest ideas you might not have thought of in order to get a good result and utilise your space to the best effect.

  • “Great experience and very efficient”

    Ben was very helpful and friendly throughout the whole process. Having never done a build before and being pretty clueless, the whole team were so supportive and explained everything to us. Everyone was really friendly, efficient, honest and super hard working. We were really lucky to have such a great team and we love our new home.

  • “Ahead of schedule and on budget”

    We recently had Ben and his team do our 4 metre kitchen extension and a loft conversion comprising of master bedroom and ensuite. Ben is a true professional, excellent at his job, from day one right through to the project’s completion. Ben was always available to answer questions and offer advice.
