Kindergarten Kekec by Arhitektura Jure Kotnik — Ljubljana, Slovenia

An extension of a typical Slovenian prefab kindergarten from the ’80s, the colorful, interactive design is a response to the school’s lack of play equipment. The addition’s three exterior walls are made of “toy slats”: natural wooden planks that the kids can play with to “get to know different colors, experience wood as a natural material and constantly change the appearance of their kindergarten, all at the same time.”

This takes the Montessori philosophy of the importance of tactile learning to a whole new level!
