Visitor Tip

Buy a timed ticket online if you can, then go straight to the glass floor early in your visit—don’t ‘save it for later’ when queues and nerves are worse.

✦
Insider Note

The magic isn’t the height—it’s the calibration: elevator choreography, compression at entry, then the slow reveal of horizon curvature and lake/land geometry.

Design & Structure

Shell Structure
⚙
Computational Process

A mega-infrastructure project: rigorous structural analysis, wind response engineering, and construction sequencing designed around vertical slipforming/poured concrete logic rather than expressive surface-making.

◆
Materiality

Reinforced concrete as mass, damping, and durability; glass as controlled fear delivery system.

△
Structural Innovation

A tall concrete shaft behaves like a giant cantilever—wind governs everything (comfort, acceleration limits, detailing, elevator performance).
