Would be awesome for Jr's room! It's a toy car storage garage! I've seen these made using TP rolls, but the PVC pipe and timber frame is much sturdier and long lasting for Toddler play :)
Stuffed Animal Zoo- give the kids a hat with 'Zoo keeper'.And let the Zoo keeper clean up ;-) Needed this 20 years ago when my mom sent my 3 kids over 101 stuffed animals until I put a stop to it!
Craft Room: IKEA fintorp mounted under cabinet holding art supplies
Art area in play room- wall mounted paper roll and the colored pencils and chalkboard wall
