    • PROBLEM TO BE SOLVED: To provide a demolition method for a building, which dispenses with large-sized heavy equipment in construction of a shielding body and enables constant securement of scaffolding required for demolition work for the building. SOLUTION: Guide supports 2 are erected at prescribed intervals on a side periphery of the building (a) to be demolished; the shielding body 1, which is made vertically slidable in such a manner as to be guided by the guide supports 2, is built in such a manner as to surround the side periphery of the building (a) at a height of ground level or a low-rise floor of the building (a); and demolition machines 8-10 are housed in the shielding body 1. A guide support material 2a is extended upward, and the uppermost-floor side periphery of the building (a) is wrapped in the shielding body 1 made to ascend while guided by the guide supports 2. The building (a) is demolished by repeating operations such that the shielding body 1 housing the demolition machines 8-10 is made to descend while guided by the guide supports 2 and such that the guide supports 2 are shortened, each time demolition of one floor is completed during the demolition of the building (a) by the demolition machines 8-10.
