Menlo Park city council has approved Facebook’s plans to construct a second campus on the west of Bayfront Expressway, near its headquarters in California, US.

The council has approved a package of land use entitlements and agreements associated with the West Campus project and sanctioned re-zoning the site so the building can exceed 35ft in height, while covering 55% of the property rather than a maximum of 50%.

Expected to accommodate 3,400 additional employees, the new 433,555ft2 building will be built on 22 acres of land and will have offices built above a surface-level parking lot, according to the Mercury News. It will be linked to Facebook’s original campus via a tunnel under an expressway.

Facebook previously agreed with the council to make a one-time payment of $1.1m for capital improvement projects, and donate $500,000 for serving residents in specific neighborhoods.
