Great responses already provided.Additionally details on points already covered, because these are very important besides other stuff and people need to pay more attention:
1. Size of the room and ratio of length, width and height is important. A ceiling height of at least 9 feet would be great.
2. As much symmetry in the room as possible - consider locations for speaker placement, chair placement and entry door. If you need to have windows, make sure that left and right side windows are symmetric, so that you can treat them equally.
3. If you can make the room sound proof, late night listening can be phenomenal.
Hope you post some pics once the room is done. Good luck!
