Microsoft cofounder Paul Allen has just picked up the penthouse apartment of a luxury building on Manhattan's Upper East Side, the Observer reports.
Allen reportedly paid $25 million for the pad, which has a huge terrace and was unlisted (so sadly, no photos).
It's not the first apartment Allen has bought in the building on East 66th St. He purchased the 11th floor apartment in 1996 for a reported $13.5 million, and the Observer speculates that "he will be expanding like a mid-90′s Microsoft."
Allen bought the penthouse apartment from Australian businessman Wade F.B. Thompson.
Allen, a billionaire tech investor, is currently selling a private island off the coast of Washington.
