There is a fundamental need to fulfill the performance criteria of apartment houses since the method of modular construction is not satisfied with it. this research is a part of project, “Development of consumer customized prefabricated housing and construction of field-test” by national R&D, and the aims are technical development to meet construction standard and fuctional qualification via Mock-up.

This study intended to explore the MC design methods of modular construction as well as the design methods of Design standards. Modular construction is generally characterized with module dimension of 3M(300mm) appearing in the form

Modular Housing has benefits to reduce the production time on-site and cost down. It is possible to expand the space by connecting the unit. For this reason, recently, modular remodeling market is growing. this study is suggests plans for modular housing remodeling process.

In this study, we have proposed a modular construction method can lower the reinforcement cost of the building, to shorten the construction period. We have developed a Mock-up, it is intended to use as basic data to the activation of the vertical extension of future reform.
