Sam and his team recently completed a loft conversion for us, and we can’t recommend them enough. Where we had been let down by other professionals previously, SB construction went above and beyond to ensure that the build was able to go ahead. And wow what a transformation we couldn’t be happier. Not only the build itself is fantastic, but the family run feel and that personal touch made the whole build experience enjoyable.
