Construction began in 2011, and was originally expected to finish the following year. As it was underway, "Southern Metropolis Daily" reported the complaints of a Shenzhen architect, Ping Caohan, that the CARDEG architects had essentially copied an earlier conceptual design of his for the tower. His design, which won the first round of the competition, consisted of five similar towers with observation pods, all in a ring at the top rather than at different levels. He did not enter his design in the second round, however, and the CARDEG architects said theirs was unrelated.
