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
A laundry room next to the master bedroom. The hamper goes into the master closet, and pulls out into the laundry room. Separate shelves for folded clean laundry. This would also work really well in a hall closet opening up to the laundry room.
