Googie architecture is a form of modern architecture, a subdivision of futurist architecture influenced by car culture, jets, the Space Age, and the Atomic Age.  Googie architecture originated in Southern California during the late 1940s and continued into the mid-1960s.

700 and 740 W. Colfax Avenue


On December 23, 2013 a Certificate of Non-Historic Status was posted for the property at 700 West Colfax Avenue. This International style office building, originally home to the National Cash Register Co., was built in 1955. Designed by notable Denver architect Temple Buell, it is an example of the International style.

On December 26, 2013 a Certificate of Non-Historic Status was also posted for the property at 740 West Colfax Avenue, better known as the Denver Diner. This Googie style building, completed in 1966, hearkens back to the Atomic Age with its sloping roof and plate glass windows. Originally a White Spot diner, it became the Denver Diner in 1990.

A Certificate of Non-Historic Status is generally a precursor to demolition, and clears the way for a demolition application to be processed without further historic review for five years. Once a Certificate of Non-Historic application notice has been posted, the community has 21 days in which to respond and potentially submit a designation application.

While the Denver Diner in particular has great sentimental value to Denverites, after staff evaluation and a meeting of the Preservation Committee, Historic Denver has decided not to pursue designation of these properties.

When a Certificate of Non-Historic Status is posted for a property that is possibly eligible for historic designation, the City and County of Denver notifies Historic Denver, Inc. Historic Denver, Inc. reviews all such properties and has an evaluation system in place to determine the best course of action. The evaluation process includes discussion of the property's significance, the number of people it impacts, its potential for revitalization or reuse, and the community's interest.

It is not yet known if and when these building might be demolished, but we know everyone out there has a story of a late night or early morning spent at the diner. We encourage you to share your recollections on our Facebook page HERE!
