In Dumont, CO

 guest room

This guest room was added in a tree house.  The house itself is very small and not really any room for out of town guest.  The solution was build a tree house that can double as a guest room.  Its 240 sq ft with a deck, sliding windows and a lock on hatch door for animal safety.  For the summer vacationers, this is perfect.  The guest who have stayed in it, love it!  Privacy for out-of-towners and its a Colorado adventure.
