PROBLEM TO BE SOLVED: To enhance the earthquake resisting performance of an existing building by maintaining a function of the existing building on an as-is basis and mounting a seismic strengthening structure on the outside surface of a building structure. SOLUTION: A pin supporting portion 20 is formed in a beam-column joint 2 on the outer surface of the existing building 1. An outer shell reinforcing frame 11 is supported by the pin supporting portion 20. The outer shell reinforcing frame 11 is composed of an outer shell beam frame 12 which continues in a beam direction, and outer shell column frames 13 which are elongated upward and downward from respective layers so that the beam-column joint can be formed of the outer shell beam frame 12 and the pin supporting portion 20, respectively. A gap between the outer shell column frames 13 elongated upward or downward is connected for the construction of the lattice-shaped outer shell reinforcing frame 11 on the outside surface of the existing building 1.
