An interlocking spatial relationship results from the overlapping of two volumes and the resultant area of shared space. When two spaces interlock their volumes this way, each maintains its identity as a space. The interlocking area of the two volumes can be equally shared by each space.

Interlocking space indicates the relationship between two such spaces having their volumes overlapping giving an identity to space and the common space is hence the area of mutual sharing.
