The tower rotates gently as it rises, a turn of a few degrees per floor. The twist creates self-shading fins and deep reveals on the sunniest sides, cutting solar gain by 35 percent compared with a conventional curtain wall of the same size.

The same geometry gives every floor a distinct view and a slightly different floor plate. At the base, a shaded public arcade and a sky garden on the 24th floor give tenants and visitors places to pause outside the air-conditioned core.
