Beacon Capital Partners has placed its Polk and Taylor buildings in Crystal City on the market.

The firm has enlisted Cushman & Wakefield to market the two connected buildings at the northwest corner of Crystal Drive and 26th Street South, which Beacon acquired as part of a larger portfolio acquisition from Blackstone Group back in 2007. The buildings are currently assessed at a combined $351.2M, the Washington Business Journal reports.

Last year, the GSA re-upped the Department of Defense’s lease of nearly 912k SF at the buildings, which will keep the DOD in place until 2025. The Taylor building at 2530 Crystal Drive and the Polk building at 2521 S Clark St are being referred to as the Pentagon Center in marketing materials.

This is the second area property to be placed on the market recently by Beacon. Back in October, the firm placed the Hunters Branch office complex near the Vienna/Fairfax-GMU Metro station up for sale. The twin 12-story buildings have nearly 412k SF of Class-A office space and are currently 97% occupied. [WBJ]
