Plan
SOM
Y-shaped floor plan is ideal for residential program • Maximizes window perimeter to floor plate area• Is inherently stable
Buttressed core• Three wings arranged around central core• Each wing supports other two
Setbacks occur at each wing in a spiraling pattern • Reduces vortex shedding by changing building
shape 24 times • Modular system = no transfers
All high performance concrete construction• Reinforced concrete core walls linked to exterior
columns• More rigid structure = less motion
