Although children's physical environments play an important role in their development, there have been few empirical studies on the interior design of early childhood centres. This is partly due to a lack of adequate methods and instruments for the systematic spatial investigation of educational environments. In light of this, the following paper presents a qualitative method for such systematic investigation, which we shall call "visual environment analysis." It also presents the results of the application of this method to ten early childhood centre environments, which can be ranged between the two extremes of restraint and expressiveness. The analysis shows that early childhood centre environments may be shaped by partly conflicting aims, such as giving children as much freedom as possible on the one hand and providing them with a stimulating atmosphere on the other. The paper therefore discusses both "visual environment analysis" as a method and, in applying this method, the interior design of a number of educational environments.
