HistoryThis 18,765 sq. foot one-story brick building was built in 1941 as a storage building and later was used for Kaiser Industries Administration offices at the main area of the Denver Ordnance Plant during World War II. Original windows consisted of mostly continuous rows of steel - sash, awning type windows set about seven feet high on the north, south, and west elevations. Original plans show that the east elevation had a small concrete and brick loading deck with a single loading bay. The original building had a wood frame penthouse centered on the roof. In 1963, the majority of the windows on the north, south and west elevations were removed and replaced with insulated panels and new openings with aluminum sash windows were created beneath these windows. In that year, the existing wood roof penthouse was removed and replaced with a larger one of steel construction. In 1979, the one-story tee addition was added to the south elevation, adding to the buildings area by 30 percent. Major interior alterations were also included to the original building as part of this project. The building is presently used as government offices and labs.
