In this paper, the authors tried to clarify the developmental process of children's cognition of housing space by comparing the floor plans of their dwelling houses, one drawn by children at school and the other drawn by their parents at home independently. Samples were 887 pairs of the floor plans drawn by children 6 to 12 years old and their parents. The following results were obtained with regard to pupils' floor plans. 1) The accuracy of the plans compared with those drawn by parents increases with the age of the children. 2) Both the external form of the house and the connection of rooms became more accurate with age. 3) Plans incomparable with those drawn by parents are divided into four types according to the drawing processes : simple partitioning of the original outline, connection of rooms to one original room, connection of rooms to the corridor, and arrangement of rooms within the original outline without the connection among them.
