The Co-Op Group took inspiration from architecture around the globe and developed the tallest building in the United Kingdom and the first office building to incorporate air conditioning. The building continues to set new standards in creating stimulating work space. Inspired by Chicago’s impressive ‘inland steel building', construction of the CIS Tower began in 1959 and was completed in 1962.
