Manhattan buildings evacuated as residential skyscraper conversion threatens collapse
A record-setting capital stack now under scrutiny
The financial scale of the project puts the incident squarely in mortgage and commercial real estate lending circles. Developers David Werner and Nathan Berman’s Metro Loft Management are converting the property into a complex of more than 1,600 luxury and affordable units, targeted for completion in late 2027, per The Real Deal. Werner acquired the leasehold for $407 million and, with Alexandria Real Estate Equities before buying out that stake, paid $142 million for an adjacent building at 219 East 42nd Street also under redevelopment.
The financing behind the project has itself been record-setting. Madison Realty Capital provided a $700 million construction loan in May 2025 — the largest ever written for a residential conversion in New York, per The Real Deal and Commercial Observer — while Northwind Group supplied $75 million in acquisition financing in 2024 and a further $135 million tied to the smaller building. Architect Gensler has billed the combined project, which includes adding more than a dozen new stories atop the original tower, as the largest office-to-residential conversion in the country.
How lenders and insurers respond to Tuesday’s structural failure will be closely watched. Conversion projects already carry a heavier financing burden than ground-up construction, typically requiring bridge and mezzanine debt, C-PACE financing and tax-credit layers stitched into bespoke capital stacks, MPA has previously reported. Brokers working conversion deals have described themselves less as loan conduits than as “problem solvers engineering a full financial solution” — a description now likely to face a real-world stress test.
A boom built on necessity
The tower’s troubles land amid a historic surge in office conversions nationally. More than 149 million square feet of U.S. office space is now proposed for conversion, with a record 48 million square feet added in a single recent year, per CommercialEdge data reported by MPA. New York City’s tracked pipeline could yield roughly 17,400 net new housing units, per the city comptroller’s office, cited by J.P. Morgan Commercial Banking, and roughly 23 million square feet of Manhattan office space is now proposed for conversion under the city’s Office Conversion Accelerator program.
That momentum is driven by necessity: the national office vacancy rate stood at 19.4% in May, up 160 basis points year-over-year, per CommercialEdge. But adaptive reuse carries execution risk ground-up development doesn’t — retrofitting steel and concrete built for office loads to bear added residential floors is technically demanding. Cliff Jensen, business agent for the steamfitters union, told reporters workers noticed beams “suddenly buckling” and windows breaking, and suggested — without official confirmation — that insufficient steel had been used to support added floors. Officials have not determined a cause.
