After just over one year of construction, Rockwood Capital is nearing completion on its expansion of the Playa Jefferson office campus.

The property, located at 12777 W. Jefferson Boulevard in Playa Vista, already offers 200,000 square feet of rentable space, leased by companies such as engineering firm Arup and social media giant Facebook.  The expansion project - known as Building E - adds 55,000 square feet to that total.

The Gensler-designed building rises three stories, offering floor-to-ceiling windows and numerous outdoor decks.  A portion of its third level is cantilevered over a surface parking lot fronting Jefferson Boulevard.

Construction of Building E followed the completion of a five-story, 617-car parking structure at the back of the Playa Jefferson campus.
