A Study on the Plan Type of the Urban LDK House in Japan - By the Combination of Plan Composition Elements -

In this research, a representative type of the housing plan was extracted on the basis of elements that exert the influence on the discrimination of the plan type, in other words, plan composition. Firstly, `connection type of the room` and `composition type of LDK (living room, dining room and kitchen)` were selected as elements of the plan type. Secondly, three forms of `connection type of the room` became clear namely `middle corridor type`, `living room centered type` and `entrance hall type`, as the factors that discriminate plan composition specifically. Thirdly, `LD/K type` and `L/D/K type` were confirmed as the factors in `composition type of LDK`. Finally, four combinations of plan type, such as `living room centered type-LD/K type`, `middle corridor type-LD/K type`, `living room centered type-L/D/K type` and `entrance hall type-LD/K type` were confirmed as the representative types. These four combinations are the representative plan types of the urban LDK houses in Japan.
