Description of the Bow

The Bow is an office tower being built for Encana, one of the largest Energy Companies in North America. It is comprised of two buildings, including a main office tower and a cultural/retail podium, spanning two full city blocks. It also will encapsulate two heritage buildings (one being the Royal Canadian Legion #1, which is a provincial historic resource and not officially part of the development) as well as the facade of the York Hotel. The project was sold to H&R REIT to develop, and the lead architectural firm is Foster and Partners from London, UK. The main tower will be the tallest building in Canada outside of Toronto at 236m and also the crown of Calgary's skyline.
