PROBLEM TO BE SOLVED: To suppress an increase in cost and the extension of a construction term and hardly affects a construction plan when arranging a base-isolated device between a lower structure of reinforced concrete construction and a relatively lightweight superstructure of steel construction. SOLUTION: In a base-isolated building A, a base-isolated plate E having a face larger than the horizontal cross section of the column of the lower structure is fixed to the upper end of the column of the lower structure B of reinforced concrete construction, and the base-isolated device D is mounted or fixed on the upper face of the base-isolated plate, and the superstructure C of steel construction is constructed through the base-isolated device. A plate ceiling member 24 for covering the superstructure C from the below is arranged and the ceiling member is supported by the superstructure C in a position which is below the base-isolated plate E of the lower structure B with an interval S2 between the lower structure and the base-isolated plate. Windshield members 40 which prevent the inflow of air from the gaps S2 and allow the relative displacement of the base-isolated plates and the ceiling members are arranged between the base-isolated plates E and the ceiling members 24.
