Lower Manhattan grew by shrinking its office stock

Commercial Observer's 25-year retrospective, built on CoStar data, puts the Financial District's office stock at 115 million square feet today against 139 million around Sept. 11, 2001. Its rental apartment count rose from 19,000 to 30,000 over the same quarter-century. That 11,000-apartment addition—the flip side of 24 million square feet of office removed—is why the outlet now calls the district a model for other urban hubs, including Midtown.

The report is careful to note that the transformation predates the attacks; the old banking district was already evolving. The quarter-century that followed gave the shift a public purpose, as owners and their public-sector allies built a diversified local economy. CoStar's current pipeline shows that work is still under way: 3,900 rental units under construction in Lower Manhattan, plus 2 million square feet of office being developed, as the district turned from a daytime financial hub into a neighborhood with a residential floor beneath its office towers.

The clearest example of how the remaining office stock is being let is Cammeby's International's work at the Woolworth Building. There, Aisling Gregory—founder of Reverdie Group and the executive who managed the repositioning after ten years at Silverstein Properties—treats the tower as a microcosm of the district. The nickname Cathedral of Commerce now describes a building leased to small and mid-size companies that can sign quickly, take prebuilt suites, and count on cafes, wine bars, a French culinary concept and a social club. Gregory says Cammeby's layers experiential programming into the asset rather than spending millions operating amenities itself, and she frames the neighborhood's evolution in two steps: convincing people to come downtown, then convincing them to enter the office.

Office conviction is climbing among investors: a SitusAMC survey this publication covered in August put office preference at 11 percent in the second quarter, up from 4 percent in early 2025. But Lower Manhattan's record suggests that conviction belongs on selective deals, because the district never waited for occupancy to fill 139 million square feet. It cut 24 million square feet from inventory and put apartments where overbuilt office no longer worked. Cammeby's leasing technique only matters because the market is smaller. Midtown should read the same logic: the buildings that recover will be the ones positioned for a future with less, not more, office.
