432 Park Avenue: how high will towers go?
Innovations in concrete frames have prompted a new generation of supertall, superslim towers to rise over New York, with 432 Park Avenue as a prime example. Architect Rafael Viñoly has designed this building with a unique reinforced concrete core, which provides the tower with both structural strength and weight. The core contains the buildings lifts and two fire escape stairs while allowing for an internal column free layout in the rest of the building, enabling maximum open interior space on each floor between the core and shell. The external façade of the tower consists of a grid like concrete perimeter featuring five open-air “drum floors”. These drum floors are a signature architectural feature, yet also house the building’s mechanical equipment.
