I tweeted about this a couple weeks ago, but here's a link to a story done in the Washington Business Journal about NASA headquarters renewing its lease at Two Independence Square, located at 4th & E Street. From the article:
At the neighboring One Independence Square, the Office of the Comptroller of the Currency (OCC) leases space, but that agency is moving down the street to Constitution Center.The General Services Administration said Thursday it has signed a 597,253-square-foot lease for the National Aeronautics and Space Administration at Piedmont Office Realty Trust Inc.’s 300 E St. SW, opting for the space agency to stay in place at its current headquarters. The space agency had been on a closely watched prowl for about 600,000 square feet of District space for just shy of a year. It will stay in the same space under a new 15-year lease at an annual rent of $44.54 per square foot, the GSA said. As part of the succeeding lease, Piedmont will renovate the interior of the building over the next year.
