The aim of this paper is to clarify the characteristics of spaces in “Free schools” from the viewpoint of children's ways of placing. The result of field surveys and analysis are as follows;
1) “The directions of spaces” are different of kinds of furniture or partitions. As a result, they are classified 10 types.
2) Children's ways of placing are classified 7 plus 3 types. It is important to plan spaces following these types because children would like to communicate with the other children by using the directions of spaces.
3) Because children do activities with invisible communication between children, it is important to plan a whole atmosphere of a “Free school” .
