Abstract
The changeability of building in the life cycle for the remodeling, the renovation, or the extension become important matter for the building management. This paper proposes 4 kinds of classification and difinition of building changeability. Type O : changeability for the usual alternation without any construction work. Type I : previously instituted changeability of interior finishes and equipments. Type II : changeability for unexpected remodeling without any skeletal work. Type III : changeability of buillding skeleton or building shape itself. Any type of building requires characteristic changeability suitable for the type of building use and the required service level.
