In the case of the carridor facing to living rooms, the corridor is seemed to be devided exclusively into each house by the ecological observation of inhabitant's behavior. This phenomenon causes others' eyes' invation to decrease to the certen level. And if inhabitants are conscious that the front area of each house-unit is their own territory, they feel defensible against others' eyes' invasion. On the contrary, general activities of house-wives and children on the corridor are depressed to the certine degree unfortunately. In this study, I would present some space-design devices in order to solve this kind of contrudiction. (1) window of LD facing towards corridor openly and dominantly (2) exclusive buffer-zone attached to each window of LD (3) eye-screen by plants, flowers and others (4) keep inside dominant by making vertical difference between inside and outside eye-levels (5) 7-20-100 house-units grouping and each common space And I propose a new design method of high-rise apartment-house buildings "LIVING ACCESS" where inhabitant live open to the corridor defencively and use the corridor for outdoor-behavior without any depresion.
