•Gross area tower : 279,000 sq. M

•Gross area podium : 186,000 sq. M

•Total concrete quantity tower : 145 000 cubic M

Structural Overview

• Y-shaped floor plan is ideal for residential program – Maximizes window perimeter to floor plate area– Is inherently stable

• Buttressed core

R

– Three wings arranged around central core– Each wing supports other two

• Setbacks occur at each wing in a spiraling pattern

TOW

ER

Setbacks occur at each wing in a spiraling pattern – Reduces vortex shedding by changing building shape 2
