Tower Fifth

AAI Architects, P.C. is the Architect of Record for this new office tower in midtown Manhattan designed by Gensler. Located east of Fifth Avenue between 51st and 52nd Street, the tower will be sited adjacent to St. Patrick’s Cathedral. At ground floor, a glass-enclosed public galleria will span the entire block to frame views of the Cathedral. The tower itself will be wrapped in an innovative, energy-efficient Closed Cavity Façade system to reduce solar heat gain by over 70%.

The 1.3-million-square-foot tower will contain 960,000 square feet of office space as well as shops, a food hall, and an auditorium. At the top of the tower, the city’s highest observatory will offer unprecedented views of Manhattan.

When complete, the 1556-foot-tall scheme will be the second-tallest building in the Western Hemisphere.
