About The Bow

A Tall Order In 2005, Foster + Partners were selected to design new headquarters for Encana Corporation, a North American energy giant based in Calgary. With its employees formerly housed in a number of buildings around the city, Encana needed a landmark building that would bring its staff together and, in providing a superb working environment, help the company to attract and retain the most talented people. Their vision translated into a brief for almost 186,000 square meters of office accommodation, along with abundant retail and public space. See Project Case Study
