Collapse zone declared, buildings evacuated as Manhattan skyscraper starts to buckle

A Midtown Manhattan tower undergoing the largest office-to-residential conversion in U.S. history has thrown parts onto the pavement below after two support columns buckled, forcing evacuations across nine buildings near Grand Central Terminal. No injuries have been reported yet. But the financing behind the stalled project is a more relevant story for advisors than the building itself. 

Fire officials said columns buckled on the 21st and 22nd floors of 235 East 42nd Street, the former Pfizer headquarters, shortly before 8 a.m., causing floors between the 21st and 26th to sag. New York City Fire Commissioner Lillian Bonsignore established a "collapse zone," though FDNY Chief of Department John Esposito said the concern is for a "localized collapse," not a total one. Mayor Zohran Mamdani called it "an extremely serious situation." Evacuated buildings include a Hampton Inn, a private school with roughly 400 students, and the Episcopal Church Center — no major wealth management or brokerage offices appear to be among them. 

The real exposure: private credit, not equity 

The building's conversion — led by developers David Werner and Nathan Berman's Metro Loft Management — is financed largely by Madison Realty Capital, a New York private credit manager with $24 billion in assets under management as of Dec. 31, 2025, per the firm's own disclosures. Madison provided a construction loan of roughly $700 million to $720 million in 2025 — sources differ on the exact figure — which the firm calls the largest ever written for a residential conversion in New York, according to Commercial Observer and The Real Deal. Northwind Group separately provided $75 million in acquisition financing in 2024 and another $135 million tied to an adjacent building, per Bisnow and The Real Deal. 

Madison's debt funds are raised almost entirely from institutional limited partners — pension funds and other large investors — rather than sold directly to retail clients. But the structure reflects a broader trend worth tracking: private credit vehicles targeting commercial real estate, including office-to-residential conversions, have proliferated in interval funds, non-traded BDCs and evergreen structures now marketed to accredited and high-net-worth investors. Advisors recommending exposure to CRE-focused private credit have some indirect stake in how underwriting for adaptive-reuse projects like this one holds up. 

A public REIT that already walked away 

One name likely to draw client questions: Alexandria Real Estate Equities (NYSE: ARE), a publicly traded life-sciences REIT that co-owned the property with Werner starting in 2018. Alexandria fully exited its stake, selling its remaining interest to Werner and Metro Loft in a deal that closed in October 2024, according to Commercial Observer and Bisnow. Advisors with clients holding ARE, directly or through REIT funds, can note that the company has no current ownership exposure to the building.

A conversion boom advisors are increasingly asked about  

The incident lands amid a historic wave of office-to-residential conversions that has become a talking point in client conversations about real estate allocations. Roughly 90,300 apartment units are now in the national office-to-residential conversion pipeline — up 28% year-over-year and nearly four times the 2022 level — according to a March 2026 RentCafe analysis of Yardi Matrix data. New York City leads by a wide margin, with 16,358 apartments in development, about double Washington, D.C. Separately, the city comptroller's office estimates that roughly 44 post-pandemic conversion projects, aided by the 467-m tax exemption, could produce approximately 17,400 apartments. 

Notably, that pipeline keeps growing even though the broader office market has been improving, not worsening — national office vacancy stood at roughly 17.6% to 17.8% as of the first quarter of 2026, down more than 200 basis points year-over-year, according to Yardi Matrix data. The continued conversion surge appears to be driven more by tax incentives and decisions locked in during the depths of the pandemic-era office glut than by fresh distress. Conversions still carry engineering risk that ground-up development doesn't, since structures built for office loads must be reinforced to bear added residential floors. Cliff Jensen, business agent for the steamfitters union, told reporters at the scene that workers had noticed the beams beginning to fail: "Somebody saw that the concrete was coming down," he said. "The beams started bending, the windows started busting." He also suggested — without official confirmation — that insufficient steel had been used to support added floors. City officials have not determined a cause, and the general contractor, identified in permit records as 235 GC LLC, has a violation history that outlets report inconsistently, ranging from seven to 13 violations and $32,000 to $39,000 in fines. 

Metro Loft said in a statement it is "working closely with the Department of Buildings to understand the full scope of the situation," adding that "the safety of our workers and the public has always been, and remains, our top priority." The cause is likely to be determined only after emergency trusses are installed. 

For advisors, the takeaway isn't that any specific client holding is at risk today — it's that the adaptive-reuse financing boom underpinning a growing slice of private real estate credit is now facing a live, public test of how well it was underwritten.
