My older two boys share a room and sleep in bunk beds. Since we moved them to bunk beds it's been great as it has opened up a ton of space in their room for quiet time away from the chaos of the rest of the house. I love bunk beds.
Bedroom loft in a tiny home. Love all the various shades of white and off-white in this bedroom. The sheepskin rug is a great idea since you are likely crawling on the hard surface when using this tiny home loft.
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.
