I had the pleasure of using Twinn build for a loft conversion on my house, I couldn’t fault the process from start to finish. I would highly recommend Twinn Build services to anyone considering having any building work/loft conversion done.


Twinn-build brought a personal and professional approach to my project. They did my tiled pitched roof on the house and the GRP roof on the extension. I now have the best looking roof on the road! I Can’t recommend them enough!
