To provide an uneven settlement preventing method for a building reducing the construction cost of the building and moreover hardly causing uneven settlement.
In this uneven settlement preventing method for the building, the ground G in almost the whole area of a building construction range is excavated below the ground surface GL to form an excavated pit 5 of approximately constant depth D, and a building lower part 3 comprising floor concrete 1 and a spread foundation 2 projected downward from the floor concrete is provided in the excavated pit without backfilling a space between the lower face 4 of the floor concrete and the bottom face 6 of the excavated pit with the excavated soil. A lightweight material 7 smaller in bulk specific gravity than the excavated soil in the excavated pit is laid on the bottom face side to bury the building lower part so that the lower face of the floor concrete can be supported by the bottom face of the excavated pit through the lightweight material. Excavated soil C is mounded at the outer peripheral part of the building A so that the buried depth E of the building lower part is the approximately balanced depth of the building weight and the total weight of the excavated soil equivalent to the total volume of the volume of the building buried part and the volume of the lightweight material.
