111 Murray Street
Nestled in Lower Manhattan, 111 Murray features a distinctive silhouette that subtly flares from its 40th floor to its crown.
DeSimone served as structural engineer for the 63-story residential tower, which includes a standalone annex for MEP infrastructure and retail.
Prioritizing open-plan luxury living, we eliminated interior columns to offer sweeping corner views. To accomplish this, we specified high-strength concrete and cantilevered slabs, transferring loads to a central core and wing-wall system that eliminated the need for corner supports.

The tower’s lower 40 stories rely on a central core, four wing walls, and four perimeter columns; above that, the wing walls fall away, replaced by eight perimeter columns that work in tandem with the core.
The building’s proximity to a supertall tower—One World Trade Center—introduced unique aerodynamic challenges. Wind tunnel testing showed amplified accelerations due to redirected gusts, threatening resident comfort. To minimize the effect of these forces, we called for a 570-ton tuned mass damper to be installed at the top of the tower, supplemented by thicker slabs and walls to boost stiffness and mass.
Through close collaboration with the architects, we delivered a structure that supports modern luxury living and uninterrupted views while overcoming the aerodynamic challenges of a dense urban skyline.
