This project is an office building situated close to JR Yotsuya Station and Shinjuku-Dori Street. The site is a perfect location: its northwest side connected to the street and the east side facing a temple, thus the open view from the building is assured semi-permanently.  This is one of the ESCALIER series, continued from its predecessor ESCALIER Gobancho.

The architect secures three openings by lay-outing the elevator core to the southwest side. Using the maximum of a sky factor, the volumes of each floor are shifted to back and forth or right and left, so that every floor is recognized as an individual rental space while the balcony becoming as a green intermediate space between the office and the city environment.
