Plastering- 16 Oct 2024
Ben and his colleagues have done a brilliant job of re-rendering the outside of my house in South Warwickshire. I really can't fault the team's work. They were all very keen to ensure that we were happy with the work. The project was undertaken in some challenging weather conditions at times and we did have some delays as a result. Communication was excellent. We always knew what was happening. I would very highly recommend BespokeBuilds to anyone needing rendering or plastering. Excellent!

Extensions- 4 Apr 2025
Ian Hamblett was a great choice of builder for our downstairs extension across the back of the house. We wanted to turn a small, dark kitchen and dining room into one larger room and extend out. Ian helped us to plan and budget, taking us through options, before finally coming up with a plan of action. We didn't feel pressurised to go ahead, but when we did, everything ran pretty smoothly. Ian's team were polite, tidy and considerate of neighbours and made sure we were comfortable. We felt included in the process at all times. Ian also installed a kitchen and flooring. We love the modern dark grey aluminium doors and windows and the skylights flood more light into the new room. The new patio is a great addition and outdoor living space. He found bricks to match our 1960's house brick and slate synthetic roof tiles. Before the extension, Ian's company installed new windows at the front of the house so we knew they were trustworthy and reliable. Thanks to all for an amazing job.

We highly recommend David. The work to replace our garage door, with window and wall, has exceeded our expectations, looks as if it has always been there! The care he took to match the bricks and get the right style window to match the rest of the bungalow was excellent, even to the painiting of the walls to match the original interior. He consulted us every step of the way and advised us the best possible way to acheive the best outcome. Always arrived when he said he was coming and kept us informed every day of what would be done the next day. If we have any other projects in the future , we will definately ask David first.
