Who doesn't like a cozy little nook to sleep in? This design makes great use of the space allowing enough room for 4 people to sleep, each with their own private quarter. Great idea for a guest house or cottage bedroom.
Guest room- Create a nook like this by suspending curtain rods from the ceiling. Put a daybed to be the bed in a small bedroom. Closing curtains allows you privacy to maximize all space for lounge and storage- its ok to have chairs right up to the bed!
Built-in bunk beds is a great idea to preserve space. The built-in book shelves also help to create more storage for toys, books and etc. The first step of the ladder has been eliminated in order to add under bed storage/trundle.
