The transaction was hardly a one-man show. "It was a group effort between Stellar, Ackman-Ziff, our attorneys Robert Ivanhoe and Stephen Rabinowitz of Greenberg Traurig, the lenders, and our financial partners," Stellar's Robert Rosania says in a comment to GlobeSt.com.

Located off the Capital Beltway at 11215 Oak Leaf Dr., Berkshire Towers is a 19-story high-rise structure situated on a 26-acre parcel of land. The property, which began to rise from the ground in 1965 and underwent a complete remodeling in 1997, boasts a total building area of more than one million sf. It has been seven years since Berkshire Towers was on the market. Berkshire Realty Holdings acquired the building in 1996 for $53 million from Turtle Creek Associates, which had held the property in its real estate portfolio since 1979.

Putting the financial package together was no piece of cake. "It wasn't easy," Ackman-Ziff's Patrick Hanlon tells GlobeSt.com. "It is a really big property and we were operating in what was essentially a wartime environment. So, it was difficult geopolitically; we were working with lenders from three different countries."
