PROBLEM TO BE SOLVED: To provide a construction method for a towering structure, which can be applied to the ordinary towering structure, and which employs a lift up method dispensing with a large-scale jack. SOLUTION: The towering structure 10 is equipped with a steel tower body 20 which is formed in a tubular shape, and an antenna steel tower 30 which has a lower end connected to an upper section of the steel tower body 20. In the construction method for the towering structure 10, the steel tower body 20 is constructed; the antenna steel tower 30 is constructed inside the steel tower body 20, and lifted up while a reaction force is applied to the steel tower body 20 by a lifting and lowering device 70; and the lower end of the steel tower 30 is connected to the upper section of the steel tower body 20.
