When looking at an architectural redesign or improving the learning environment look for ways to create more open spaces and remove boundaries. This could be done with opening doors or using different furniture.
At Fuji, for example, between April and November, the sliding doors are completely open. The distinction between where outside stops and where inside starts doesn’t apply. There are no walls between spaces, and therefore no boundaries.
There are also only boxes, used as furniture to indicate areas. The principal believes that when you place children in a cage they will try to establish a social hierarchy, and the outcasts get segregated; but when you have no boundaries, there is no need to create such hierarchies.
