Remassing

390 madison

In a remarkable feat of engineering, three million pounds of concrete and over 160,000 sq. ft. are being demolished in the building’s base to re-mass and reconfigure the structure. This includes the removal of two full floors to create nearly 100,000 SF of double height space. Floors 9 through 12 will be paired back by nearly 25% to create a more efficient floorplate.

The entirety of the demolished floor area is being added to the top of the structure in the form of eight entirely new floors.
