A Midtown Manhattan high-rise undergoing a historic commercial-to-residential transformation has been successfully “stabilized” after a structural emergency halted work and forced neighborhood evacuations on Tuesday, New York City Mayor Zohran Mamdani announced.
“The structure has not shown any further movement since yesterday morning,” Mayor Mamdani stated during a Wednesday press conference. “It remains under continuous observation while emergency shoring and stabilization work continues.”
The emergency began Tuesday morning at 235 East 42nd Street, the former global headquarters of pharmaceutical giant Pfizer. Two load-bearing structural columns on the 21st floor of the high-rise buckled, causing surrounding floors to sag. While the incident triggered initial reports of falling bricks and fears of a localized collapse, no injuries were reported.
First responders immediately cordoned off the busy corridor near Grand Central Terminal, ordering full evacuations of four adjacent buildings—including local hotels, shops, and apartments—and a partial evacuation of a fifth.

Emergency crews worked through the night to install temporary structural shoring and reinforce the compromised steel beams. According to the New York City Department of Buildings (DOB), these efforts have successfully arrested any further shifting within the tower.
The 33-story tower is currently the site of the largest office-to-residential adaptive reuse project in the United States. Spearheaded by developers Metro Loft and David Werner Real Estate Investments, the 1.3-million-square-foot redevelopment aims to add an 11-story vertical expansion to the existing structure.
Scheduled for completion in early 2027, the project is designed to convert the former corporate headquarters into approximately 1,600 luxury rental apartments, complete with a fitness center and a rooftop pool.
Despite the localized structural failure, city officials reaffirmed their commitment to repurposing empty commercial real estate to address New York’s ongoing housing shortages.

“I continue to believe that converting offices into housing is part of the answer to our housing crisis,” Mayor Mamdani said, echoing the goals of his administration’s broader housing initiatives. “But I also believe that these conversions must be executed safely, with all parties assuming full responsibility.”
The mayor promised a thorough investigation into the root cause of the structural failure to determine whether contractors adhered strictly to approved blueprints. Metro Loft CEO Nathan Berman downplayed long-term structural concerns, describing the incident as an isolated case of human error involving a fraction of the building’s thousands of reinforced columns, and estimating a construction delay of only a few weeks.
