In our country, the application of the design method of face to face dimension in wall-slab apartment has passed 10 years. So MC(Modular Coordination) design method has fixed in the design step to some degree. In Design and Work Execution of House the exclusive area of the apartment was calculated by face to face dimension. And the term of face to face dimension was known broadly to clients, construction company, etc. But design method of face to face dimension is not to simply extend the room size so far as wall depth in design process but to ensure the actual space should be considered with efficient use and assembly of building components. That is to say, Design method of face to face dimension is not to be defined by design step but to be related with construction and maintenance. However in construction process the point of face to face design method was not understood even now. So the purpose of this study is to analyze the effect of demonstrating standard last finishes. As a fist stage, we apply for patents and produced 3 standard last finishes. And then we constructed the standard last finishes for 2 construction sites. This study analze the effect about three viewpoints, there are workability, economics and standardization effect. Through this analysis, we know that standardization using the reference plane and standard last finish must have application from planing stage till construction stage. It is a way to maximize the standardization effect.
