Meta Platform's (formerly Facebook) newest campus in Menlo Park, California was designed by architect Frank Gehry and constructed between 2017 and 2018. The office building, called MPK 21, has nearly 10 acres (4 hectares) of interior space and a 3.6-acre (1.5-hectare) rooftop garden with 200 trees. A water recycling system saves the building around 17 million gallons of water per year, and 1.4 megawatts of solar panels provide a renewable energy source. 37.481292°, -122.153642° Source imagery: N
