This is AMAZING! What a smart idea for a growing child's room to truly give them a place of their own without the bed necessarily being the on-the-floor focus!
Secret room behind the closet-this would be a good place for a safe room or a library.
Forcing tulips in water is a fun, easy, and a unique way to present tulips that most people have not seen before. I think showing the natural beauty of the bulb is a pure, modern, and minimalist approach to floral design. Give it a try.
