Rethinking the Vision of Architecture in an Alley: expecting our neighbors to see a landscape fills with greenery rather than blunt architecture. The architecture has a series of setback space for terrace and balcony so that the residence has more soothing and comfortable living space. On the outside, the greens on the building reduce the oppression seeing from the ground level in an alley; on the inside, every residence has two subareas (3M and 4.2M) in the space composition for creating livable home lifestyle and suggesting the possibility of living space flexibility.
