Kids loft bed with storage underneath-would be good for large bed as well. I love these types of beds, so much storage. I always wanted one when I was a teenager but back then no body made this kind of thing in Canada.
Mstr bdrm trayed ceiling & 2 walk-in closets (make into one). Great room with vaulted ceiling, fireplace flanked with built-in shelves. Laundry room, kitchen pantry, two covered porches (make kitchen and dinning space bigger)
