To provide a warehouse, in which membrane-body construction works at a high place are minimized and the construction works of each frame are conducted efficiently, and a construction method therefor.

A plurality of plane trusses 21, in which column materials 25 and principal rafter materials 26 are assembled integrally, are composed of a frame structure, in which a plurality of main frame truss blocks 20 stiffened by an auxiliary material are coupled only by horizontal splicing materials 35, and a membrane body 1 covering the whole frame structure. Each main frame truss block 20 is divided beforehand and assembled on the ground at the time of construction, and arranged at regular intervals under the state, in which upper blocks are placed temporarily on lower blocks. The membrane body 1 covering the whole is developed and fixed temporarily on the main frame truss blocks 20. The lower blocks and the upper blocks are hung up and erected, and the completed main frame truss blocks 20 are connected mutually only by the horizontal splicing materials 35. The same operation is repeated, and the whole is completed.
