PROBLEM TO BE SOLVED: To provide a prefabricated simple shed easily carried and easily assembled at an installation site by lightening the weight of precast concrete members. SOLUTION: Sidewall members 1 and roof members 2 composed of light- weight precast concrete of air dried specific gravity 1.5 or less and compression strength 20 N/mm2 or more are prepared beforehand using light-weight aggregate. At the installation site, after the side wall members 1 are mounted on a foundation concrete 6 placed till prescribed thickness, the residual concrete is placed in the inside and the outer circumference of the side wall members 1 respectively to integrate the side wall members 1 with the foundation concrete 6 and the roof member 2 is joined on the sidewall members 1.
