Calgary’s Bow: An iconic skyscraper revisited
+ Read More
With its iconic crescent-shaped, inversely curved form, the Bow is a striking presence on Calgary’s skyline. Designed by Foster + Partners of London, this 59-storey tower features a vast atrium partitioned in four clear-height sectors with the façade integrating an architectural exposed diagonal grid structure in six-storey segments. The perimeter ‘diagrid’ frame helps make up the building’s hybrid lateral force-resisting system (LFRS).
