We visited the show site and Andy talked us through their approach, all options etc and answered our many questions. Impressed by their Buy British and eco low-waste credentials. On a visit to our garden, Andy mocked up plans and visuals that were very helpful. We found Andy to be polite and professional at all times, and very responsive to messages. While shopping around, we have come across some companies that you wouldn't trust to water your plants, let alone manage a building project at your home. We felt quite at ease with Andy, no 'rogue trader' vibes from him at all, and we recommend talking to him/Kingdom Rooms about your project.
