JBG Smith, just weeks removed from winning D.C.'s biggest economic prize in a generation in Crystal City, is already reaping side benefits.

The REIT signed National Cooperative Bank to a 15-year extension on its 66K SF lease at 2011 Crystal Drive, it announced Monday. The building is a few blocks from where Amazon is leasing space from JBG Smith for Phase 1 of its HQ2 requirement.

The bank has been in Crystal City for more than a decade, initially moving to take advantage of the value proposition. Now, it is poised to benefit from the surge of young workers that will come to the area, as well as the increased brand recognition.

JBG Smith announced the deal as a new lease in "National Landing," the rebranded neighborhood that combines pieces of Pentagon City, Crystal City and Potomac Yard. It did not release when the extension was negotiated or how related it was to Amazon's decision.
