PROBLEM TO BE SOLVED: To provide a construction method of a steel structure applicable also to a steel structure whose plane shape is other than a rectangle. SOLUTION: The construction method for constructing the steel structure 1 having a sky block 1b built over an existing facility 1a, at a predetermined story or higher comprises sequentially carrying out each step of (1) an independent column installation step, (2) a start working platform construction step, (3) a frame assembling step, (4) a frame moving step, (5) a frame extension step, (6) an extension-movement step, (7) a column joining step and (8) a beam repositioning step to carry out preceding construction using the partial block of the steel structure 1 as a start working platform 3, to frame the moving frame 4 on a start working platform 3, to mount an inner guide 5b to the lowest story and to guide the inner guide 5b in a predetermined moving direction so as not to horizontally deviate by a horizontal guide 24 provided at the top part of each independent column 2, thereby sliding the moving frame 4 by a predetermined span in a predetermined direction to construct the steel structure 1.
