Loft Conversion- 12 Jul 2026
We couldn't be happier with our new attic conversion. Drew and his team were absolutely fantastic from start to finish. The results are incredible and have completely transformed the space – the quality of workmanship is outstanding. Throughout the whole project, Drew kept us informed every step of the way, explaining what was happening and making sure we were happy with everything. The team were always punctual, professional, friendly and respectful of our home, leaving everything as clean and tidy as possible at the end of each day. Nothing was ever too much trouble, and any questions we had were answered quickly. It's clear that Drew takes great pride in his work, and the attention to detail really shows in the finished result. I would highly recommend Drew and his team to anyone considering an attic conversion or any building work. Thank you all for doing such an amazing job – we're absolutely delighted with our new space!

Extensions- 19 May 2021
Oli and his expert, friendly team have installed a turn-key annexe in 4 weeks, on time and in budget. I was particularly impressed with communication, thoughtfulness to our requirements and situation and even keeping relationships with neighbours at an even keel. A great balance of keeping me informed and involved with decision making but also using his initiative and judgement to progress the build without delay given we are a busy family with almost continuous zoom calls! I'd highly recommend this contractor and will use again for our future home development needs. 100%
