The Port Authority of New York and New Jersey’s Board of Commissioners approved a new architectural design developed for the exterior cladding system that will cover the 185-foot tall secure base of One World Trade Center.

The board, at its November meeting, authorized $37.2 million toward project and contract costs with Permasteelisa North America Corp. to engineer, fabricate, and install the new panelized facade, which will consist of stainless steel slat panels around the building’s concrete base covered with glass fins. The glass fins will reflect light during the day.
