Children's Bed - Looks Like A Little House Headboard . instructions seem to be in Dutch, you can try translating it into English but you get the idea for a cute bed that you could copy from the picture and the dimensions of a twin size bed.
I'm imagining a twin Loft bed over a double bed(dressed to look like a drawbridge) with towers and turrets made from tall, narrow bookcases and improvised stairs from Homedepot.gotta check some second hand stores!
