PURPOSE: A construction method of a box structure is provided to obtain efficiency and economic feasibility in carriage and installation by constructing a precast wall and manufacturing the wall in order not to have large self-loads. CONSTITUTION: A construction method of a box structure (A) comprises the following steps. The ground on which the box structure is constructed is excavated, and a plurality of precast walls (200) is installed in the excavated space. Cast-in-place concrete is placed in a lower space (S) of the wall, and a bottom plate (100) is formed. The bottom plate and both sides of the walls are strongly coupled. An upper plate (300) is constructed on the upper part of the wall.
