Meet the Team

Paul Sivyour has been in the building trade for over 20 years. His friendly team are polite, clean and conscientious; they think of themselves as guests in your home at all times.


"We were delighted with the work Paul and his team did on our attic conversion. When other builders turned the job down due to the potential complications, Paul's 'can-do' attitude, flexibility and vision exceeded our expectations. Both he and his team of builders were exceptionally reliable, friendly and trustworthy. Any problems were dealt with quickly and without fuss, and they made a huge effort to keep the site tidy and to reduce the impact on the rest of the house, which was important for us with a toddler running around!

Most importantly, the project was managed right through from initial design to final decoration, and everything was completed to an extremely high standard. We would not hesitate to recommend them."
