1) The brief was to create an ambient advert for the roof of the Hothouse building to promote the brand message of "It Has To Be Heinz". 2) The initial ideas focused on slogans portraying Heinz as a family member or friend but these concepts were too large for the space. 3) Inspired by Heinz's use of recycled materials, the final idea selected was large hot air balloons made of Heinz cans on the roof, visually striking and supporting Heinz's environmental efforts.
