The purpose of this study is to suggest an optimum guide line of the unit plan design in national housing (less than $85m^2$ of exclusive floor area in a dwelling unit). The unit plan of apartment have been improved diversely for the residents, and the family members per household have been decreased for decades comparing with the past. In contrast, the living space per household has been increased steadily, it is because of the improvement of the living standard. The unit plan have been improved from 2-bay corridor access type and 2~3 and 4-bay staircase type. In december 2005, the balcony was permitted to be used as exclusive living area without the increase of the original living area by law. So the apartment residents have been able to use more spacious area exclusively in a dwelling unit. On the other hand, the legalization on permitting balcony area into a exclusive area resulted in a distorted wide and enlarged plan only for the business profit improvement lately. The living environment has been changed differently unlike at the time of the legislation of the national housing. The family member per household has been decreased and the related law and the institution has also been changed. Moreover It has passed 40 years since the legislation of national housing ($85m^2$). So, The size of national housing should be reviewed according to the current trend in terms of the decrease of household and the utilization of balcony area.

The investigation of the apartment housing as a dwelling type has become the most important and popular research subject to understand the housing culture in Korea. In their methods of typological analysis, it is found that most studies represent each unit plan as a simplified architectural drawing. This type of typology, however, has difficulties in processing a large scale of data set because each representation of a plan contain too many informations. To deal with this problem, this study suggests a new graph-theoretical method by which apartment plans can be represented in a more simple and effective way. This new method is also tested against the sample plans from Gangnam-gu area in Seoul to reveal the design logic hidden in plan configuration. Through a series of analyses, it is verified that there exist a design strategy that guides the particular pattern of zoning and allocation of each room in the plan.

Present structure design has a problem arising from the fact that present apartment housing design doesn't satisfy user's diverse demand. An aim of this study on searching out the alternative to solve this problem. The results of study are as follows : 1) Methods of flexible structure are analyzed to reflect user's needs and practical example of those proposed. 2) To raise the flexibility of design reinforced concrete pannel wall system are selected. The basic types of T and II for the figures of pannel are adopted. As a result it brought so much open space not having influenced on the load of construction that it enhances the flexibility of the space allocation. Also that made it easy to meet the user's demand for 8 kinds of plan types are easily designed according to the arrangement of the space and its scale.

The residential apartments have become a choice of a popular housing space since the first establishment of Mapo apartment in 1962. Therefore, the residential market experienced a bloom where residential apartments were sold as they were built simultaneously. However, this phenomenon was turned around and unsold lots appeared after the period of IMF and as the construction companies put out more various apartments by differing the characters and the strategies in building apartments. As a result, the leadership of residential market moved from the suppliers to consumers, in consequence, the wants of the consumers became more demanding. The consumer can freely control the number of rooms with a variable wall system or a bigger sized apartment with two entrances to the living room as well as having a bathroom with a master bedroom in a small-sized apartment. Many conceptual trials like this were taken to improve the residential environment and to give a change to the unit plan of the public housing. From these changes, one can observe a general trend that is taking place in current residential housing. Consequently, this study is on the type classification of unit plans in public housing built after 1999 and dwelled from 2001. The objectives of this study are to confirm the characteristics of the unit plans applied in recent public housing and provide basic materials that can be incorporated to residential space plan from now and hereafter.

Apartments have become the most popular type of residential building in Korea since the 1960s. The dwelling space should be designed to accomodate various life styles or changing needs of family members. This research is conducted to analyze flexible interior space types of apartments and to improve the architectural planning and design of apartments that can satisfy various needs of residents. In this study, apartments of 10 - 90 pyeongs built in the region of Seoul, between 1998 and 2007, are investigated in terms of the unit plan, the number of open sides, and a distribution of flexible apartment types for each year, Apartments with flexible space are classified into 10 different types, including a flexible type between bedrooms, a flexible type between a bedroom and the livingroom, and a flexible type between the dinning room and the livingroom. According to the composition of unit plans, apartments are also differentiated as a single-corridor type, a double-corridor type, a stairway type, a hall type, and a combination type. According to these classifications, the characteristics of desirable unit plans were analyzed. The results of the analysis showed that, as the unit size of apartments get bigger, the ratio of width/depth of the front side unit plan is increased. This result reflects a trend of high-rise apartments which have an increased number of front-side bays and a shorter depth for better penetration of daylight. In addition, a hall type is found to have a wider front side and shorter depth. According to open sides, a flexible type of the livingroom and the dinning room/kitchen (L-D.K) is found to be most common for the front/back open space, and the livingroom is usually placed on the front/side open space. To meet the changing needs of residents, more research should be conducted on flexible dwelling space.
