After nearly a year in limbo, the 243,221-square-foot office building on M Street Southeast, (one block from Nationals Park) has a new owner.

Northwood Investors, a real estate investment management firm in New York, bought the building’s ground lease at an auction Thursday for $57 million. The sale is part of the bankruptcy proceedings of developer Opus East, which racked up nearly $60 million in construction debt associated with the development. Bank of America is the primary creditor.
