Hi there, we took a reference from this great forum when we were looking for some built in shelves and went for a guy called Ben Fletcher who runs Spaced In
http://www.spacedin.co.uk/index.html.
He was very reasonably priced, very good at coming up with ideas, absolutely delivered on time and to budget, was easy to work with, gentle and self effacing. And no, I don't know him personally at all! I was just so thrilled at how wonderful nappyvalleynet works at helping us find out these things. It was just great
