The 13-story structure is the fourth office property at the Corporate Office Centre at Tysons II, a five-million-sf, mixed-use project under development by Lerner Enterprises. Harvey-Cleary Builders is serving as the general contractor for the new office facility.

Joining the tenant roster are Declaration Management & Research LLC and investment banking firm Houlihan Lokey Howard & Zukin, both of which leased an entire floor for a total of 49,200 sf. Investment concern Red Zone Capital Management Co. LLC signed on for 12,100 sf. PricewaterhouseCoopers--which propelled the building's development with a lease commitment of 160,000 sf for its regional headquarters in early 2004, later increasing its take to 184,600 sf--took on an additional floor in the Kohn Pedersen Fox Associates-designed building for a total of about 209,000 sf.
