We've featured an indoor playhouse and an indoor treehouse to inspire you. If you haven't yet drawn up your plans, hold off a bit to ponder this - an indoor playhouse built under the stairs.

This work of genius was created by Marcie and her husband. Rather than take up space elsewhere in the room, they built a charming playhouse right under the staircase. The location makes it clever but the details make it special. We love the shingles, the Dutch door, flower box, and lantern. Want to know what's inside? Run over to Marcie's blog Mossy for more details.
