Facebook announced today that it has partnered with OMA to design the masterplan for Willow Campus, a mixed-use neighborhood adjacent to their existing headquarters in Menlo Park. 

"The first official step will be the filing of our plan with Menlo Park in July 2017. We will begin more formal conversations with local government officials and community organizations over the course of the review process, which we expect to last approximately two years."—writes John Tenales, VP Global Facilities and Real Estate. "We envision construction will follow in phases, with the first to include the grocery, retail, housing and office completed in early 2021, and subsequent phases will take two years each to complete."

Facebook also plans on building 1,500 units of housing on the campus, 15% of which will be offered at below market rates to mitigate traffic impacts from growth.
