In this paper the structure of open space system which has been built in the blocks of traditional Machiya-style dwellings and the momentum of its changes are presented hypothetically. This structure of open space system is such a situation of the physical environments affecting the quality and quantity of open spaces in residential sites that it is possible for every resident to enjoy the various utilities from open spaces interdependently. And the reference frame of its changes is based upon a theoretical postulate which is set up in analytical process of the social systems.
