Seattle Times: Facebook could double Seattle presence with another big new office

Facebook is only 12 years old. Love it or hate it, this company has changed the world (and our city) in some drastic ways.


Seattle is already home to Facebook’s largest engineering office outside its Silicon Valley headquarters, and the company is leasing another South Lake Union project.


Facebook, which just opened a big Seattle office, is expanding again by leasing a pair of new South Lake Union buildings with the potential to double the tech giant’s presence in Seattle.

Paul Allen’s Vulcan Real Estate announced Friday that Facebook will be the sole office tenant of its new $246 million Arbor Blocks project along 8th Avenue between Harrison and Thomas streets.


The two buildings will total 383,900 square feet of office space when they open. For perspective, Facebook this spring just moved most of its roughly 1,000 employees in the area into a new building on Dexter Ave N. that is 335,000 square feet.

The current Facebook office has potential to hold about 2,000 employees total, and the upcoming offices are slightly bigger.

Construction on the Arbor Blocks project, which consists of two six-story offices with ground-floor retail, is slated to start later this month. Facebook could move in during the third quarter of 2018.

The Menlo Park, Calif.-based company first opened an office in Seattle in 2010 and the city now houses its largest engineering outpost outside of its Silicon Valley headquarters.

Seattle-based teams have led development of the Facebook Messenger chat service’s video calling and the “cold storage” technology that helps company data centers more efficiently store the photos and other content people post to the social-networking site, among other initiatives.

“Seattle is really a key part of our long-term mission,” Mike Schroepfer, Facebook’s chief technology officer, said in May.

Vulcan is also building the new Google campus in South Lake Union and has built most of Amazon’s constellation of buildings in the neighborhood.
