In the recent remodeling construction for old apartment, it is general to extend the parking space for the increased cars for residents. This paper reviews the extension methods of parking space and presents the problems that must be solved for the construction. In this paper, three extension cases of parking space in the remodeling projects were reviewed. As a result, the demand for the extension needs to be analyzed for the various cases and the technologies for the best-fitted construction should be suggested based on the demand.

This study is to introduce a structural analysis method that can apply a unit modular system to a remodeling extension. The structural analysis process, which can reflect the behaviors between the existing building and the modular system, is performed in a five-staged structural analysis. Therefore, the example of structural analysis of an existing building is introduced.
