Drop-down attic shelves
This idea is very undeveloped, but seems promising. Beside the light switch in your living room and/or bedroom, another switch that causes a 5 foot by 5 foot by 5 foot square cube cabinet to lower down out of the attic with doors on it. The cabinet itself would also have controls on it for sending it back up. It could house maybe a mirror and makeup station on one side (for her) and men's stuff on the other side.
