Our Recent Projects

    • “After 5 years of living here we are moving to the country and it breaks my heart to leave the beautiful house that you created for us. I wanted to say thanks again for the beautiful work that you did on our building – it’s been amazing to live in and you guys did a first class job. Would always recommend you if someone asked for an excellent contractor.”

      – Nick H
    • “This house is cosy and comfortable but in a natural way. Our old house was of similar scale, area and build and if you wanted to heat a room you had to blast it and the air would then be very dry and that heat would quickly leak out.”

      – Toni M
    • “The Grade II listing permission required a lot of flexibility in the building, planning and scheduling and real close cooperation between Prewett Bizley and Bow Tie who managed very well, putting in contingencies and safety nets in case planned windows were not approved. There was a flexible approach to managing a dynamic project. In the end we did achieve exactly what we wanted with secondary glazing as a result of Prewett Bizley and Bow Tie’s consistent and careful lobbying of Islington planning department until they agreed with what was proposed.”

      – Toni M
    • “Rafael demonstrated a great knowledge in respect of building work and was able to draw plans and give advice regarding interior design. He was not only a competent builder but was fully involved in a complete refurbishment job from conception to realisation. The finish result was amazing and is a great demonstration of Rafael’s skills.”

      – Carole R
    • “Not only was the work done to exactingly high standards but Rafael made many excellent suggestions which resulted in a build which made more sense.”
