In the heart of Manhattan, where office buildings once symbolized the relentless pulse of American commerce, the winds of change are reshaping skylines and revitalizing urban cores. The Flatiron Building, a storied New York landmark, will soon shed its identity as an office building to emerge as luxury condominiums. This is just one chapter in the larger story of how a crisis in office real estate has opened a new frontier for developers, city planners, and visionaries alike: office-to-residential conversions.
The transformation of office towers into housing addresses two pressing challenges: rising office vacancies and a housing shortage in urban centers. Over 70 conversion projects, delivering more than 10,000 apartments, have already been completed in 2024. With an additional 94 projects under way and over 300 planned, the pipeline is robust. While conversions won’t singlehandedly solve either crisis, they represent a promising strategy to reimagine how urban spaces are used.
Why Now?
For years, the economics of converting offices to housing simply didn’t work. Aging office properties were priced too high, and their layouts often posed insurmountable challenges. However, as office vacancies reached record highs and values of second-tier buildings plummeted, a seismic shift began. Sellers, desperate to offload underperforming assets, started accepting steep discounts. This recalibration in prices is enabling developers to acquire properties at rates that make conversion financially feasible.
In 2024, Manhattan office building sales intended for conversion accounted for half of the $1.12 billion in transactions, according to Ariel Property Advisors. Cities like Cleveland, Washington, D.C., and Chicago are leading the charge, rolling out tax breaks and subsidies to incentivize redevelopment. In Cleveland, 12% of the city’s office inventory is either undergoing or planned for conversion. Developers are seizing the moment, turning once-pristine office addresses into thriving residential hubs.
Revitalizing Depressed Business Districts
At the heart of this movement is the desire to breathe life back into hollowed-out business districts. Cities like Washington, D.C., are prime examples. With federal employees still working remotely in large numbers, demand for office space has waned. Developers like Post Brothers have capitalized on this trend, acquiring properties like 2100 M Street for just $66 million—a fraction of its 2007 peak valuation of $150 million.
“Without significant demand for office use, these properties need to be repositioned,” says Matt Pestronk, president of Post Brothers. “Conversions are one of the best tools to ensure these spaces remain active and valuable.”
Public incentives further bolster these projects. Cleveland’s Public Square, for instance, is now surrounded by redevelopment projects after a $50 million upgrade added fountains, green paths, and an amphitheater. These enhancements have turned what was once a declining transit hub into a magnet for new residents.
Creative Solutions to Old Problems
Despite the enthusiasm, converting offices into residences isn’t always straightforward. Many older office buildings weren’t designed with residential needs in mind. Oversized floor plates can limit access to light and ventilation, a critical issue for residential units. Developers are employing innovative solutions to overcome these hurdles. In Manhattan, GFP Real Estate is installing two massive light wells at its 25 Water Street project to ensure apartments meet modern living standards.
“You end up with so much space that you paid so little for, you can create amenities that would never make financial sense with new construction,” explains Daniel Neidich, CEO of Dune Real Estate Partners. His firm has teamed up with TF Cornerstone to invest $1 billion in 20 conversion projects across the U.S. over the next three years.
Challenges Ahead
Not everyone is convinced that conversions are the golden ticket. Some developers argue that the costs—relocating tenants, installing atriums for light, and addressing design constraints—can rival those of new construction. “When your costs start to approach those of building new, the financial case for conversion falls apart,” says Miki Naftali, a veteran of New York real estate.
Yet others see the potential for conversions to become a skill set in their own right. Developers like William Rudin are retaining minority stakes in conversion projects, treating them as a learning opportunity for future ventures. “The world is looking at these assets in a different way,” Rudin says, reflecting a broader shift in how urban spaces are being reimagined.
A Glimpse into the Future
As the movement gains traction, high-profile projects are making headlines. Detroit’s Renaissance Center, long a symbol of the Motor City’s resilience, will soon house apartments and a hotel. In Cincinnati, the Union Central Life Insurance Building is being converted into over 280 residential units complete with a rooftop pool and health club. These projects underscore the transformative power of adaptive reuse.
Conversions may not solve the office crisis or significantly dent the housing shortage. Still, they represent a meaningful step toward creating vibrant, mixed-use neighborhoods that reflect the evolving needs of urban dwellers. As Julie Whelan of CBRE observes, “The pipeline keeps replenishing itself,” signaling that this trend is far from a passing fad.
By turning yesterday’s office towers into tomorrow’s homes, cities across the U.S. are finding creative ways to adapt, thrive, and build a new urban future.
