Conversions - General- 24 Oct 2023
Leigh is an exceptionally patient and reliable builder. He played a vital role in converting our garage into a bedroom, completing the project with efficiency and perfection. Throughout the conversion process, he showed patience in addressing our requests and inquiries. Additionally, his fees were reasonable, and he even helped with some minor tasks at no extra cost. In summary, I strongly recommend him to anyone in need.

Gavin and Luke built a single storey extension for us. It was quite complex and they had to remove several internal and external walls. They are very nice people to work with, genuine and honest, amenable. They were here for 9 months doing our work and we are thoroughly happy with them. They are very good - I would certainly recommend them.

Extensions- 16 Sep 2025
Steve and his crew did an amazing job turning my fag-packet designs and downloaded images into a proper, wonderful sound proof garden building, concrete external & rockwool cavity He’s a an old-school builder who does things the right way. His approach and mentality are always “how are we going to do this” rather than “I can’t do this,” I picked Steve on price and previous work. He came in middle price wise and was fair, it’s safe to say it was the right choice. He was left to his own devices, worked through all sorts of weather, and although the job took a little longer than expected because of that, he stuck firmly to his original quote. Although steve didn't know at the time, the garden room was my test for both quality, work ethic and trust, and Steve passed with flying colours. On the back of this, I’ve now commissioned him to build me a two-storey extension. I think I’ll buy him his own coffee machine for that project though! ;-) Thank you, Steve
