Hangar One is one of the world’s largest freestanding structures, covering 8 acres at the Moffett Field airship hangar site at Moffett Field in Mountain View, California.

The massive hangar has long been one of the most recognizable landmarks of California’s Silicon Valley. An early example of mid-century modern architecture, it was built in the 1930s as a naval airship hangar for the USS Macon.

After finding toxic PCBs, lead and asbestos in the exterior coating, the US Navy stripped the exterior from the hangar but left the underlaying skeleton support structure intact after spraying it with a preservative. After months of planning and preparation, work to remove the exterior panels began, requiring “the biggest scaffolding job in the history of the West Coast.” The work was completed in mid-2012. In 2014, NASA & GSA selected Planetary Ventures (a subsidiary of Google) to manage Hangar One and the Moffett airfield.
