Located in Tokyo, Japan, Mode Gakuen Cocoon Tower was designed by Tange Associates. The tower floor plan is simple. Three rectangular classroom areas rotate 120 degrees around the inner core. From the 1st floor to the 50th floor, these rectangular classroom areas are arranged in a curvilinear form. The inner core consists of an elevator, staircase and shaft. The Student Lounge is located between the classrooms and face three directions, east, southwest and northwest. Greenery planted at lower levels brings nature and softness to the design and its elliptical form swathed in an aluminium curtain wall creates a form pleasing to the eye from every level whilst minimising the building’s footprint.
