PROBLEM TO BE SOLVED: To provide an intermediate base isolating structure of an existing building exhibiting a base isolating effect by efficiently concentrating the deformation of the existing building caused by an earthquake, on a base isolating bearing arranged at an intermediate story. SOLUTION: The intermediate base isolating structure 1 of the existing building is composed of a natural rubber based laminated rubber bearing 10 (hereinafter referred to simply as "laminated rubber bearing 10"); a brace type damper 20 serving as a seismic control member connected between a lower structure 40 located below the laminated rubber bearing 10, and an upper structure 50 located above the laminated rubber bearing 10; and a reinforcing brace 30 installed within the plane of structure of the lower structure 40.
