The Union Iron Works Turbine Machine Shop was an industrial building of steel frame construction with curtain walls of red brick and industrial sash. It was one of the most impressive early 20th century industrial buildings in the San Francisco Bay Area. When it was built, it was the largest building of its kind on the Pacific Coast.

The building was deigned by John Reid, Jr., an architect best known for his contributions to the San Francisco Civic Center and as a designer of San Francisco school buildings.

The building was the largest and most prominent building in a shipyard that played an important role in both World Wars.

The Union Iron Works Turbine Machine Shop was demolished in 1984.
