Report
I got in touch with SUB Build for a rear extension on our semi-detached home. They took care of everything from start to finish, and the workmanship is top quality. What impressed me most was their communication and how clean they kept the site. You can tell they take pride in what they do.

Having one team to manage our entire loft conversion was a game-changer. SUB BUILD LTD did it all, and the result was a seamless process and a beautiful space. Their project manager kept us in the loop at every step.

very happy to recommend this building company. Mitchell the boss was thorough, patient and kind to our elderly mother. They did not go off on other jobs. The kitchen was completed on time with absolutely no problems. Our Mother is delighted and so are we. Thank you Mitchell `
