Microsoft Redmond Campus, Corporate building complex in Redmond, United States

Microsoft Redmond Campus is a large corporate complex in Redmond, Washington, covering 502 acres (203 hectares). The site includes 83 buildings with offices, meeting rooms, and research facilities connected by pathways and underground passages.

The company moved its headquarters to this location in February 1986, investing 25 million dollars in the first construction phase. Shortly after, in March of that same year, the corporation began trading its shares publicly.

The company art collection displays pieces across the entire site, including installations from artists based in the Puget Sound region. Many works come from veterans and members of different communities who bring their perspectives into the work environment.

The site offers several cafes, transit hubs, walking paths, and sports fields for visitors and employees. Underground tunnels connect the buildings and allow material transport without using outdoor routes.

The pond between the original buildings was nicknamed "Lake Bill" after Bill Gates, not for koi but for a ritual: after a successful product launch, managers were thrown into the water. The original buildings were numbered sequentially except Building 7, skipped because a permit delay became indefinite.
