Editor’s Note: This article was originally published on April 25, 2022 and has been updated to reflect changes including the completion of Hangar One’s restoration.<\/strong><\/p>\n

Restoration has been completed on Hangar One, a historic landmark in the San Francisco Bay Area and a key part of the region\u2019s early aviation history. <\/em> <\/em><\/p>\n

In December 2025, Planetary Ventures completed restoration of the Hangar One landmark at Moffett Federal Airfield, located at NASA\u2019s Ames Research Center in California\u2019s Silicon Valley. Work focused on modernizing the structure while maintaining its original visual characteristics as closely as possible. The restoration work included the remediation, clean-up, and recladding of the siding and roof, as well as a variety of structural upgrades. Hangar One \u2014 now more than 90 years old \u2014 was restored according to U.S. Secretary of the Interior’s Standards for Rehabilitation of historical buildings.  <\/p>\n

This project started years ago when the U.S. Navy removed all the hangar\u2019s roof, siding, windows, doors, and other materials, which were contaminated with toxic chemicals. The Navy then sealed the hangar\u2019s structural frame with epoxy to ensure the chemicals would not pose a health risk, leaving it intact until further work could be completed.  <\/p>\n

In 2014, NASA signed a lease with Planetary Ventures to operate Moffett Federal Airfield and rehabilitate Hangar One. <\/p>\n

In 2022, Planetary Ventures removed the remaining toxic chemicals from the hangar. First, working section by section, areas of Hangar One were surrounded with scaffolding and encased to keep contaminated materials inside. Only then were they carefully removed and stored in the vicinity of the hangar until being taken off-site for proper disposal. After the contaminated materials were removed, the steel frame was primed and repainted to protect it from the elements until siding, windows, and doors were added.  <\/p>\n

The team also made several structural upgrades \u2014 as well as other mechanical, plumbing, electrical, landscape, and hardscape improvements \u2014 to ensure the hangar\u2019s long-term operational integrity for generations to come.  <\/p>\n
