Proper Room Acoustics/Designs

I have the chance to build, from ground-up, a new listening room. I have spoken with Dennis Foley and have learned much, concerning the proper room dimensions, as well as room designs. Instead of adding room treatment devices to deal with room nodes etc, I will be constructing a great room from the beginning. Has anyone had any experience with him directly or indirectly? BTW-I started with the Analog forum, because there is no forum, that I know of, that deals with listening rooms. Any suggestions?
