Customer Review

O.P.B. Came recommend by a family member to build my single story side extension. Once I met Paul and after a short meeting I knew OP.B. would do a good job for me. The work started in the middle of June and it was completed by the middle of August. Having never done anything like this before Paul put us at ease and explain everything throughout the whole process. Along with his professional team of staff they kept the place clean and tidy unusual for a building site. The extension is now complete and has added three new spaces to our home. I would fully recommend O.P.B. to anyone who is contemplating having any work done at home.
