A quarter century after the deadliest terrorist attack in American history, Lower Manhattan is almost unrecognizable in its vibrancy. The office workers who long dominated the city's downtown are now brushing shoulders with thousands of new residents as they grab their morning coffees. 

Arriving at this point has been a long and painful journey, punctuated by global events that echoed through the Financial District’s limestone and granite streets and undermined its recovery.

After the dust cleared in the years that followed the Sept. 11 terrorist attacks, New York’s real estate industry began planning and rebuilding the neighborhood from the ground up, a process that took longer than many hoped.

Then the Global Financial Crisis rippled through Wall Street and put a yearslong pause on new investment. Eventually, the supertalls of the new World Trade Center rose and were leased by 21st-century corporate leaders like Spotify and Uber. 

The pandemic reversed that momentum and then some. Workers everywhere deserted office towers along with their favorite cafés and happy hour spots. When employees began to return to in-person work a couple of years later, companies ditched Lower Manhattan’s older buildings in favor of Midtown’s shiny towers.

But now, after 25 years of ebbs and flows, the area is starting to fire on all cylinders.

Office space in Lower Manhattan is filling up, with some companies paying triple-digit rents, while conversions have added tens of thousands of new housing options. Property values have more than doubled in some of the neighborhood’s biggest buildings, according to a Bisnow analysis of city tax records. 

“I was a big believer in what Lower Manhattan could provide,” Dennis Friedrich, who was CEO of Brookfield Office Properties at the time of the attacks, told Bisnow. “Did I know the timeline? No, probably not.”

'Where Do We Go From Here?'

The morning of Sept. 11, 2001, started as a beautiful fall day. The sun was out, the air was crisp, and it was the perfect temperature to go for a stroll.

“It was the kind of day I was cooped up in the office and regretting it,” said Michael Cohen, the Tri-State president of Colliers, who at the time was the head of brokerage GVA Williams.

But at 8:46 a.m., a plane flew into the World Trade Center’s North Tower. At 9:03, a second plane hit the South Tower. 

Friedrich was sitting in his office in One Liberty Plaza with its corner view of the South Tower when the windows rattled. He watched in horror as the towers crumbled, shedding wreaths of paper and sending portions of the buildings raining down toward the sidewalk.

The terrorist attack killed 2,977 people, including 343 firefighters who died on the day of the attacks and 341 first responders who died of health complications in the decades that followed. 

The attacks caused between $33B and $36B in economic losses between September 2001 and June 2002, according to a report from the Federal Reserve Bank of New York. Around a third of that total was in the form of earnings losses, but cleaning the site, replacing the World Trade Center buildings, and repairing damaged buildings and infrastructure carried a $21.6B price tag. 

Within four days, amid search-and-rescue operations around the remains of the buildings and surrounded by heavy smoke, Friedrich and Brookfield’s other executives were back downtown to assess the damage to the firm’s 10M SF portfolio in the area, including One Liberty and the World Financial Center, now known as Brookfield Place. 

“Emotionally, it shifted from grief and tragedy to, ‘What are we going to do here?’” Friedrich said. 

Even properties that weren't physically damaged were affected by the ripple effects in the property market, said Dave Lyon, an executive director for JLL’s value and risk advisory services who was in his fifth year as an appraiser at the time of the attacks. It took years for the market to regain a sense of normalcy.

“[It was] not even a recovery stage but more of a, ‘Where do we go from here? How do we replace the inventory that was lost?’” he said.

Leaders were determined to rebuild the Trade Center complex, buoyed by the resolve from all levels of government and then-CEO of Silverstein Properties Larry Silverstein to resurrect the neighborhood.

But that would take years, and there were employees who needed desks. The real estate community rallied to find new locations for displaced tenants as soon as they could, with brokers working overtime to find available space and landlords keeping rents level, industry players told Bisnow. 

Friedrich said a sense of duty took hold.

“We wanted to restore our portfolio as quickly as we could, for Lower Manhattan and to demonstrate that we were going to be resilient and get through this,” he said.

Fits And Starts

As the scores of office tenants displaced by the attacks scrambled to find new spaces for their workers, many found homes in the surplus of space in Lower Manhattan created when the dot-com bubble burst. 

But overall, Lower Manhattan lost 30,000 finance, insurance and real estate workers between 2001 and 2005, according to a 2014 report from the NYC Department of City Planning. By contrast, the rest of Manhattan gained 46,800 FIRE workers.

The exodus, as well as the visceral daily reminders of the attacks on the streets of the neighborhood, pushed property values “way down,” Lyon said. 

“There's a stigma that came with having a property that is located in Downtown Manhattan,” he said. “Refinancings were very scarce at that point. There were not a lot of trades.”

In the years that followed, asking rents dropped by nearly 25%, while annual leasing volumes hovered around 6M SF, according to Colliers data provided to Bisnow.

“It took awhile initially to incentivize tenants to move down there,” said Jay Neveloff, partner and chair of real estate for HSF Kramer.

The market began a slow but steady upward trajectory in 2004. It took until 2007 — the year after the new 7 World Trade Center opened as the first replacement tower in the complex — for leasing volumes to hit 2001 levels. 

Over the next few years, the final redesigns for the new World Trade towers were unveiled, and construction kicked off for an expanded Fulton Street station, Port Authority Trans-Hudson station, underground mall and the 9/11 Memorial and Museum. Simultaneously, residential conversions like 20 Exchange Place removed older office space from the market.

Between 2005 and 2007, office availability rates fell from 14.4% to 7.5%. Asking rents grew by almost $6 per SF in that period, surpassing the average for the neighborhood in 2000, according to Colliers.

Consequently, commercial property values rose: In 2004, just four of 13 Lower Manhattan skyscrapers analyzed by Bisnow had tax assessments higher than $100M. By the end of 2007, there were seven skyscrapers in that category.

“You're still coming out of the three or four years after 9/11, but we did see a recovery,” Lyon said. “There's a real resilience to that particular market.”

But then came the Great Recession, driving office property values across the city down along with the global economy. Manhattan office leasing volumes declined by 18.4% in the first year after the recession.

“Nobody was solid in the year following '08,” Cohen said. “The ebbing tide stranded all boats.”

As soon as the economy showed the first signs of pulling out of the yearslong economic slump, Lower Manhattan got a boost that still echoes for those in the real estate community: Condé Nast signing a 1M SF lease in 2011 at the still-under-construction One World Trade Center.

That deal became the catalyst for a wave of leasing by tech, media, advertising and information tenants. Between 2012 and 2017, 369 such companies signed for 9.4M SF in Lower Manhattan, according to Cushman & Wakefield.

The World Trade Center towers were partly responsible for Lower Manhattan’s newfound vitality, Cohen said, coming out of the ground at the same time as Hudson Yards.

“As it emerged from the '08 meltdown, the Trade Center buildings went toe-to-toe with the new construction elsewhere in Manhattan,” he said. 

By 2019, Lower Manhattan’s asking rents hit their highest levels on record, at $64.64 per SF. Building values had continued to skyrocket. 1WTC's assessed value had grown by roughly $500M since 2016.

But that momentum was interrupted by another global event, as the pandemic forced meetings across the world to relocate from boardrooms to Zoom. 

Resilience And Rebirth

Covid-19 erased the gains Lower Manhattan's office market had made since 9/11 and then some, with more than one-fifth of all office space sitting available in 2022. Office buildings lost millions in value as the tenancy dried up and lenders grew worried that they would never regain their pre-pandemic status.

“Covid was much more far-reaching in terms of its impact on the office industry,” Friedrich said. 

Ironically, the trauma of 9/11 helped landlords cope with the fallout and press forward with confidence that their faith in the area would be rewarded.

“What did everybody say in the heels of Covid? ‘No one's ever going to come back to the office,’” Friedrich said. “There was an important lesson learned for all of us there that — don't write New York off. We're resilient.”

The downturn led to another wave of office-to-residential conversions, with 9,297 new homes in the neighborhood between 2020 and 2025, according to a report from the NYC Comptroller’s Office.

GFP Real Estate’s conversion of an old JPMorgan Chase back office added 1,320 new homes to the neighborhood, 111 Wall St. will add another 1,568 apartments upon completion, and 80 Pine St. will provide 713 further units.

And while Midtown's shiny trophies have gobbled up the lion's share of high-profile leases, Downtown's market has been steadily finding equilibrium.

The availability rate for offices in the neighborhood now sits at 15.5%, down from 20.9% in 2023, according to Colliers. The area’s population has tripled since 2001, and its workforce, at 230,000, is almost as large as before the attacks, The Wall Street Journal reported. 

With new residents comes demand for places to socialize, eat, drink and have new experiences. While Cushman & Wakefield data shows that Lower Manhattan’s retail availability is still among the city’s highest rates, at 15.5%, conversions are spurring demand for fitness, food and beverage, and grocery stores, according to the Real Estate Board of New York.

“Wall Street area was deserted after working hours and on weekends,” GFP Real Estate CEO Jeff Gural said. “I wish it would have happened for a different reason, but the area is thriving.”

High office rents in Midtown trophy towers are starting to push tenants into the submarket, which had its best first half for leasing since 2019, according to Cushman & Wakefield.

Rents and occupancy still haven't kept pace with Midtown buildings, and the values of the Lower Manhattan buildings analyzed by Bisnow have increased, but not as fast as those of Midtown stalwarts the Empire State Building and 9 W. 57th St.

Nevertheless, in February, the recovery came full circle: American Express announced that it would move its global headquarters to 2 World Trade Center and would buy the 2M SF skyscraper-to-be from Silverstein Properties upon completion. 

It is the final piece of the World Trade Center complex designed to replace the buildings destroyed in the attacks, and it will rise above a neighborhood brimming with more momentum than it has had in 25 years.

“The final chapter on the Trade Center is still being written,” Cohen said. “Once that building is built and occupied, maybe then we'll have some closure.”
