Construction is now underway on the 66-storey Telus Sky tower in Calgary. Designed by Bjarke Ingel Group (BIG), the 761,000-square-foot skyscraper aims to be the first building in the city to obtain LEED Platinum certification.

The tower includes office, retail and residential units and will house the headquarters of telecommunications company Telus.

BIG is collaborating with local architecture studio Dialog to deliver the building, which replaces the demolished Art Central building. It will include a 500-square-metre gallery dedicated to local artists, as well as some ground-floor retail and is scheduled to complete in late 2017.

“Following the highest environmental standards, TELUS Sky will be the most significant next-generation property in Calgary’s history,” a Telus official said in a release, noting the LEED Platinum objection.
