In the column base structure of this building, the reinforcing frame members 6 constituting the independent foundations 20 and 4 prevent the buckling of the base material main body 5 and are attached via the reinforcing frame members 6 despite the independent foundations. Since the reinforcement is provided by the provided brace 23, sufficient strength to resist vertical and horizontal loads can be obtained, and in the case of a building to which a wall is attached, further reinforcement is provided.

According to this building structure, the foundation is an independent foundation spaced apart from the conventional structure in which a base is placed on a continuous foundation such as a cloth foundation and a pillar is erected on the foundation, and the pillar is erected on the foundation. Since the base can be omitted, it is inexpensive and simple in construction, which contributes to reduction of the construction period and construction cost, and is useful for construction of a simple building such as a prefabricated type.
