PROBLEM TO BE SOLVED: To provide high-rise building construction of the existing tower equipped with a communication apparatus such as an antenna capable of being constructed by reusing the existing the tower without interrupting a communication service by the communication apparatus. SOLUTION: The outline frame 2 of a form surrounding the tower 1 rises with a structure without causing any radio interference up to a height required for re-shoring of communication apparatuses 1a to 1f such as an antenna or the like with which the tower 1 is equipped, and the tower comprises a stage installed on the outline frame 2 by making re-shoring of communication apparatuses 2a to 2h such as an antenna or the like, a stage dividing a lower structure 11 of the tower 1 and an upper part 10 above the lower structure into two parts, lifting the upper part 10 of the divided tower up to the height projected upward from the upper end section of the outline frame 2 by making use of the outside frame 2 and making it support by the outline frame 2 and a stage structurally integrating the lower structure 11 of the tower 1 with the outline frame 2.
