Custom built-in bunk beds - two twins over two queens with drawer steps. Perfect for a vacation house or guest room. The queen bed accomodates adults but so many beds could also be used for sleepovers.
So much room for activities. but little, individual reading/working nooks (for a tea house or library.) -- or just a space to crash/decompress/work in a different position. And the scene from step brothers makes it even better!
