Ok, so I know this is a bedroom but it's a great use of space for a small room. I particularly like the use of the dead space behind the ladder for shelving. It could also be a cool idea for a kids play room.
A small space idea, like a tree house in your room. Utilize all space with shelf stairs up to the bed box. Get a closet too and all of it up off the floor space. Great for a boys room. Put a BB Net on the bed and voila! they can play indoors.
What an awesome idea! This would be great built in a kids walk-in closet! Just take the doors off the closet and utilize the extra space! Keep the kids clothes etc in a wardrobe in front of the closet to make it a secret hideout!
