Pinned said :Secret passageway! Cute idea if your house is designed properly. I remember a family friend's house had a hidden play room under their stairs. To get in, we crawled through a little door in their coat closet. Way fun for kids!
secret room IN the stairs! I need a secret room somewhere in my house. So have the secret room under the stairs, but to actually make it secret, don't put the door under the stairs, put it in the stairs.
The hammock is a great idea so smaller "secret playroom" areas. This kid’s bookshelf opens to a secret reading nook. A SECRET READING NOOK. I would’ve never left. (from Everything About Secret Bookcase Doors)
