World's Most Valuable Office Properties, 2026

[dimondpark]

This is not a ranking per se, because I've only looked at a few places, but this is what I came up with so far, the values were in ranges so I picked the highest value to post. I have a lot more to post but this is what I have so far...

Also, this includes all office properties, be they high rises or corporate campuses, ALSO, I combined buildings that are part of a single development but only the office space, excluding retail, hotels, entertainment that might also be part of the property..lastly take this with a grain of salt, I cross referenced between 5 different AI platforms and this is the average of their findings, so this isnt exact.

Is this owned space or also leased space?

Amazon's second-largest campus is in Bellevue, with quite a bit more than Arlington.

What square footages and values/sf did you use? It would be interesting to see the whole table and the assumptions used.

All of this is a moving target with a lot of gray areas -- for example if a company owns a space but has signed a sublease, or if fair market values have fallen by half due to the WFH trend, or if a giant TI has been permitted but not built...

I'd separate out building complexes and what individual occupants control. Apples and oranges that often don't intersect.

What's the source? There seem to be missing a lot of NYC properties such as Rockefeller Center, the Empire State Building, Brookfield Place (fka the World Financial Center), etc.

Hudson Yards would be far more valuable than WTC. Rents are easily 50% higher. It's also a much bigger complex.

[Kngkyle]

Many on that list are only worth what they are because of their tenant. If that tenant ever left they would be worth pennies on the dollar. (Apple Park, Googleplex, Microsoft Redmond, Meta Menlo, etc).

Also the Sears Tower is almost certainly not worth anywhere near $2.5B now. Most recent valuation from May 2025 has it at about $1.4b after significant renovations were completed. It was previously appraised at $1.8b in 2018 pre-renovations.

[Crawford]

If Apple ever sinks or dies, geez, I can't imagine how to reuse Apple Park. That whole complex was silly and peak hubris.

[mhays]

A campus of many smaller buildings might do ok, like Microsoft's HQ. It has grade-separated rail every eight minutes and centers on big car-free areas with parking below-ground. https://www.google.com/maps/@47.6375462,..._ep=EgoyMDI2MDUyMC4wIKXMDSoASAFQAw%3D%3D

But a giant flying saucer would need significant renovations to handle multiple tenants, and the transit is nowhere near as good.

The land value of Apple Park probably justifies the price tag. It occupies more land area than the Pentagon, and it is located in a region with some of the priciest land in the world.

The fair market value of a property is what someone is willing to pay for it, and that's almost always going to be based on NOI unless you get a unicorn owner-occupier who's willing to pay a premium for being able to consolidate operations.

I don't see any world for example in which Salesforce Tower could be worth $3.5 billion. If you apply a generous 5% cap rate to that then NOI would be $175 million/year. Assume triple net lease with all operating expenses covered by the tenant, and something like 1-2%/year in landlord overhead and you get a net rent of nearly $125/square foot, and then you have the operating expenses on top of that. Salesforce could probably shop their tenancy to any number of developers who would build a new head office for them with a lease commitment less than half of that number. How would the current owner ever realize the income necessary to justify that valuation?

The would depend on how much could be built on that land. Would Cupertino allow a dense, mixed-use district? Or just similar amounts of office? If the latter, at 175 acres and maybe $200-300/sf, it might be worth a couple billion, not nine.

Is commercial space in Cupertino that much cheaper than residential? According to Google the median price per square foot of residential is over $1,500. Hard to believe that commercial would be much cheaper.

You said land value.

True, I did. But it still seems easy to fathom that this piece of property would be worth multiple billions of dollars even without Apple's HQ on it.

Apple Park has 2.8 million square feet of commercial space, representing about 10% of the square mile piece of land that it's built on. Using median price of residential, 2.8 million square feet of residential space would be worth about $4.2bn, and that's only 10% of the land on the property. It seems more likely to me that Apple Park is undervalued, tbh.

[mhays]

Like I said, if the Cupertino allows more intense development it would be worth more. If it doesn't, then the city's normal commercial land costs (I'm hearing $200-300/sf) might be more applicable.

Those rates seem cheap for such as wealthy business center, but Cupertino limits density so much...
