Construction was halted and nearby buildings evacuated after two steel columns on the 21st floor of the former Pfizer headquarters in Midtown Manhattan buckled. The incident occurred in a 1970s-era building that is undergoing an ambitious office-to-residential conversion, billed as the city's largest, to create approximately 1,600 luxury apartments. Developers, MetroLoft, attributed the structural damage to the added weight from widening the top 15 floors of the building, though they maintained the building's overall integrity was not compromised.

The scare prompted the evacuation of several surrounding buildings, including a school, diplomatic offices, and hotels, and led to street closures in a busy part of Midtown near Grand Central. While city officials later deemed the building stable after floor-by-floor inspections revealed no further movement, structural engineering experts suggested the buckled columns are likely unrepairable and will require extensive and costly replacement, rather than simple shoring. This incident underscores the significant engineering challenges and the financial risks involved in adaptive reuse projects, especially given past violations at the site for falling debris and worker incidents.

This event highlights broader issues within the burgeoning trend of office-to-residential conversions. New York City is seeing a surge in such projects, with over 16,000 units currently in conversion and more than double last year's pace expected in 2026. However, Goldman Sachs estimated in 2024 that office prices would need to fall nearly 50% for these conversions to be financially viable at scale, and some real estate veterans believe up to 30% of office buildings are effectively worthless and may need demolition rather than conversion. This incident could lead to increased scrutiny and potentially higher costs for future conversion projects.
