Home theater room in the attic. A more do-able idea than those other fancy home theater rooms! Much cozier and warmer than the individual recliners in rows that you see in a lot of fancy home theater rooms
In what place would these awesome stairs be commonplace? Swarovski Crystal Staircase - Champs Elysees (this must be the stairway to heaven)
like the pocket doors- glass doors maybe a good idea from the great room to the 4 season porch to let the most light in. For even more light maybe fixed glass doors/windows on either side.
