Nexen Building, Calgary

The Nexen Building is a 37-story office tower that reaches 152 meters high in downtown Calgary. Its facade features stainless steel and curtain wall construction at 801 Seventh Avenue Southwest.

The building was constructed in 1982 and initially served as headquarters for NOVA Corporation. After 2000, its purpose and occupancy changed multiple times over the following decades.

The building stands out with its diagonal orientation, which differs from the typical grid pattern found in other downtown towers. This distinctive angle makes it visually distinctive among the straight-lined skyscrapers nearby.

The building is easy to spot from street level and sits within walking distance of other downtown attractions. Visitors can observe the architecture from the sidewalk and explore the surrounding area around the structure.

The building employs an innovative composite stub-girder steel-frame system that allows open floor plans without interior support columns. This technical design created spacious layouts that were considered advanced for its time.
