Can’t recommend Alex highly enough! He built wardrobes into our attic eaves, altered some stairs, and fitted our new wooden hallway flooring, all to an exceptional standard and at a very reasonable price. He was professional, tidy, efficient and consulted me every step of the way to ensure the finished design was exactly what I was after.
