Johns Manville Plaza

Johns Manville Plaza is a modern office tower in downtown Denver rising 29 stories and standing about 404 feet tall. The structure features reflective glass walls and wide columns that enclose roughly 760,000 square feet of workspace.

The building was designed by the architectural firm Hellmuth, Obata and Kassabaum and completed in 1978. Its construction marked a period of modern office tower development in downtown Denver during a time of business expansion.

This structure reflects late 20th-century office design focused on functionality and workspace efficiency within Denver's business core. Its clean lines and straightforward approach shaped how commercial buildings appeared in the downtown district during that era.

The plaza sits in downtown Denver on 17th Street and is easily reached by car or public transit. The entrance is visible from the street level, and the surrounding area offers parking options along with access to nearby shops and dining.

The structure was built by Al Cohen Construction and shares its plaza with the adjacent 707 17th Street building next door. This pairing creates a distinctive corner in the financial district where two towers frame the street together.
