The National Science Foundation currently employs about 2,100 people at its Ballston headquarters, according to a spokeswoman, but the government agency has indicated that it is potentially interested in moving to a new building when its lease expires in 2013. NSF would like the new space to be about 25 percent larger than its current location at 4201 Wilson Boulevard, and about 12.5 percent cheaper per square foot than the current comparable office rent in Ballston, according to the Washington Business Journal.
The federal government’s office rent cap in Northern Virginia is $38 per square foot, compared to the average Ballston Class A office rent of $43.47, according to WSJ. That has led to speculation that NSF might leave Ballston altogether.
