High Slenderness Ratio

The concrete framed, 200,000-square-foot building is one of the tallest new developments south of Midtown and offers condominium units with floor-to-ceiling glass windows and views of the park.

Due to its high slenderness ratio, the building’s lateral movement is mitigated by the design and incorporation of a tuned liquid damping system into the building’s structure at roof level.
