Big Offices Crash as Small Spaces Thrive, CoStar Data Shows

A Widening Split in the Office Market

Commercial real estate is no longer moving as one market — it is splitting into two very different stories. Large, trophy office towers and sprawling corporate campuses, once the crown jewels of city skylines, are shedding value at a troubling pace, while smaller, more flexible office spaces are quietly gaining ground 1. CoStar's Commercial Repeat Sale Indices put hard numbers behind the divergence: large office buildings have posted a 1.8% value decline for a second straight quarter, a slide that coincides with a national office vacancy rate hovering near 18% 2.

That vacancy figure is the backdrop for everything else happening in the sector. Big footprints that once signaled corporate prestige have become financial liabilities as hybrid work reshapes how much space companies actually need. Smaller offices, by contrast, appear better suited to tenants downsizing from larger leases or seeking more adaptable, lower-commitment space, which helps explain why they are holding or even gaining value while their larger counterparts struggle 12.

Measuring Demand More Precisely

Amid this bifurcation, industry groups are rolling out new tools to help investors and brokers make sense of where demand is actually strongest. The National Association of Realtors has launched a quarterly CRE Demand Index that ranks 306 metro areas using a combination of sector-specific job growth, population trends, and net migration data 35. The index is designed to give a forward-looking read on which markets are positioned for growth rather than simply reporting on past performance, offering a counterweight to the doom-laden narrative surrounding downtown office towers 5.

Where the Money Is Still Moving

Not all corners of commercial real estate are struggling. Morgan Stanley Real Estate Investing has urged investors to put capital to work now, specifically pointing to industrial, retail, and senior housing as sectors with stronger fundamentals than traditional office 8. That view reinforces the broader theme running through the current cycle: capital is rotating away from oversized, undifferentiated office space and toward asset classes — and building sizes — that better match how people actually work, shop, and live today.

Industry Response and Broader Implications

The divergence is prompting adjustments across the industry. Brokerages are being advised to expand strategically by identifying geographic advantages and specializing in particular asset classes rather than treating commercial real estate as a monolithic business 4. Meanwhile, gatherings such as the 37th annual Commercial Real Estate Summit at Omaha's CHI Health Center are bringing professionals together specifically to discuss strategy amid these shifting conditions 6. Even personal legal matters are being reshaped by the sector's complexity, as seen in guidance on how business owners should protect commercial property interests when a marriage ends 7.

Taken together, the coverage paints a picture of a market in transition rather than simple decline. The pain concentrated in large offices is real and measurable, but it coexists with pockets of resilience and even opportunity — a nuance that new demand-tracking tools and targeted investment strategies are increasingly built to capture.
