30 East 31st Street’s exterior work is inching closer to completion, as installation of the light-colored panels in between the windows on the bottom of the northern elevation is now underway. Located in NoMad between Park Avenue South and Madison Avenue, the 479-foot-tall residential tower is topped-out at 40 stories, and the crossed beams at the top of the podium will soon be encased with the newly arrived panels. The 88,000-square-foot project is designed by Morris Adjmi Architects and developed by Ekstein Development and Pinnacle Real Estate. Douglas Elliman Development is marketing the building’s 42 units, which will be spread across 70,070 square feet for an average of 1,700 square feet apiece. Prices will range from $1.65 to $12 million.
