Indiana Oxygen Company, Industrial heritage building in Indianapolis, United States

The Indiana Oxygen Company building is a two-story rectangular brick structure with an attached one-story U-shaped warehouse on South East Street in Indianapolis. The facility once produced hydrogen and oxygen for industrial use.

Built in 1930, the Indiana Oxygen Company building was listed on the National Register of Historic Places in 1987. The two-story brick main building with its raised basement and attached U-shaped warehouse dates from that initial construction.

The Indiana Oxygen Company building carries applied Art Deco ornament in limestone and metal on its brick main block, a decorative treatment tied to its 1930 industrial construction. The two-part layout, a two-story main building over a raised basement with a one-story U-shaped warehouse attached, shows how such plants were arranged for production and storage.

The building is listed on the National Register of Historic Places and its exterior architecture remains clearly visible from the street. Visitors can observe the industrial design and structure from the surrounding area.

The building's two parts differ in height and plan: a two-story rectangular main block on a raised basement, joined to a one-story warehouse laid out in a U shape. Both are brick, and the Art Deco limestone and metal ornament is applied to the main block rather than the warehouse.
