Chicago’s Tallest Building Fetches $1.3 Billion [updated]

Willis Tower - Chicago, Illinois - March, 2010 - 002a

Willis Tower - Chicago, Illinois - June, 2009 - 001aThe tallest building in Chicago has a new owner. MarketWatch, the news web site owned by Dow Jones, broke the news that the Blackstone finished up negotiations over the weekend to buy the Willis Tower (233 South Wacker Drive) for $1.3 billion. It’s the highest price ever paid for a building not in New York City.

The good news is that Blackstone tells MarketWatch it actually plans to invest money into the iconic tower, returning it to trophy status through upgrades to the retail space and SkyDeck Chicago, the observation level.

So, does this mean the Willis, nee Sears, Tower will become the Blackstone Tower? Probably not. Willis has a deal that lets it pay a million dollars a year for the naming rights to the building as along as it maintains a certain amount of office space there. The insurance company still has ten more years on its lease.
