Make the deminsions large enough so you can put the speakers in the middle of the room if needed. I am told by folks in the know (Joachim Gerhard at Audio Physic for example, I think the interview is at Speakerbuilding.com) that this is the best way to get clean sound but it is never done because of "aesthetic reasons."
"Totally treated with acoustical damping" would be well...very damp.
Two good sites to view on this topic are www.silcom.com/~aludwig and http://physchem.kfunigraz.ac.at/listeningroom

As you know, the room is crucial and resonates like a pipe organ. Without knowing more about your personal preferences it's a bit tough to get very specific.
Good luck.
Sincerely, I remain
