The facade is composed of undulating balconies which change slightly from floor to floor, forming a rippling, curtain-like surface.
The facade is designed to prevent bird collisions, utilizing the irregular curves of the balconies along with special glass that is opaque to birds.
Balcony depths are calculated to optimize views beyond the building perimeter, and also to optimize sun shading within units according to where it is most needed.
During construction the formwork for the curving edges was guided by a global positioning system.
