Nexen Building, Calgary, Office skyscraper in Downtown, Calgary, Canada.
The Nexen Building rises 152 meters with 37 floors, featuring stainless steel facades and a curtain wall construction at 801 Seventh Avenue Southwest.
Constructed in 1982 by CANA Construction Company for $121 million, the building initially served as headquarters for NOVA Corporation until 2000.
The structure follows modern architectural principles with its diagonal orientation, departing from the standard grid pattern of downtown Calgary buildings.
The composite stub-girder steel-frame system creates open floor plans without structural columns, offering 55,855 square meters of office space.
Since 2019, this 37-story tower holds the distinction of being the largest completely empty office building in downtown Calgary.
