Beijing Doudian Kindergarten is the supporting education facility for a new public housing community; it is a three-story building with 6 classes in total. We split the children’s space into several basic units, and reassemble them into a settlement-type building. The indoor and out door public space are naturally created by the staggered units combination. The continuous slope roof has a significant axis which is 45 degree angle rotating from the plinth below, it not only ensure the integrity of the units settlement, but also produce a group form through the differentiation of eaves and building façade.
