When i have my own preschool center, this will be an indoor play space! Nest, 1301 Locust Street, Philadelphia awesome space for kids, wish their was something like this around my house (of-course when i have kids)
large Foam core boards to brainstorm ideas. Ikea Benjamin stools hacked to keep the boards upright. They can still be used as stools when needed and are also great for creating temporary walls for project spaces.
If we ever have a playroom. I like the idea of using a tension rod between the two shelves for a curtain to create a stage for puppet shows or talent performances or hide things before company comes over! Plus I'm pretty sure everything here is from IKEA!
