12 East 48th Street‘s distinctive metallic façade panels are making their way up the northern elevation of the 31-story Midtown East structure. Arranged in a staggered pattern surrounding floor-to-ceiling windows, the bold curtain wall will create a striking contrast with the surrounding masonry-clad buildings. Located between Madison Avenue and Fifth Avenue, the slim tower is topped out and will eventually open as a 161-room Hilton Grand Vacation Hotel. The project is designed by Handel Architects and developed by Hidrock Realty.
