With the recent increase in the number of one- and two-person households, demand for small-sized apartments has been on the rise, and lifestyles have seen swift changes to cater to smaller-sized housing. The construction market is shifting toward small-sized apartments, and research is now needed on the lifestyles of those living in small-sized apartments in order to develop suitable housing units. Therefore, this study aims to produce a planning concept for housing units by lifestyle, categorizing residents based on lifestyle and identifying their LDK preferences. Regarding methodology, prior research was reviewed to validate housing-related lifestyle factors and study the lifestyles of those living in small-sized apartments. Lifestyle categories based on housing type were determined by a cluster analysis, and LDK preferences for each lifestyle were analyzed through a survey. These data were then used to propose a planning concept with small-sized apartments for each lifestyle type. Thirty-two factors for categorizing lifestyles were obtained by studying three domains of housing-related lifestyle factors: 'housing values', 'attitudes toward living space', and 'behavior in living space; A total of 648 people living in small-sized apartments were classified into three lifestyle groups: 'True Family Benefiters', 'Smart Shopaholics', and 'Slow Heritage Pursuers'. 'Each group's lifestyle characteristics and socio-demographic features were used to classify the lifestyles of those living in small-sized apartments. The LDK preferences for each lifestyle were analyzed to design a planning concept for small-sized apartment.

To analyze the space features of small-sized detached houses, this study has compared the floor plan types of detached houses and apartments. Currently small-sized detached houses are popular in Korea. The comparative analysis was focused on common residential patterns and the apartment plan. The results of space syntax were summarized as follows: four types of apartments and twelve types of small-sized detached houses were deduced by the relative spatial depth analysis. Among the sixty-seven house samples, only two of them showed the same pattern as those of apartments, which showed that each room of detached houses had distinct difference with those of apartments. According to the integration and control analysis, each space of apartments showed difference within narrow range, while the space of detached housed showed difference within wide range. In addition, the detached houses showed distinct relations between the center of space and the surroundings, and there are distinct differences between the easier layouts for access rooms and difficult ones. Moreover, the living rooms of detached houses somewhat exist under the low integration condition, and they cannot be standardized in the center of house, which are different with those of apartments. The master bedrooms of detached houses exit at the surrounding space same as those of apartments. Nevertheless the toilet is in the master bedroom which made its control lower than those of apartments.

The parking problem is caused by the parking demand. The ratio of parking demand at multi-family housing sites has been increased significantly, therefore several parking problems have occurred. The goal of this study is to investigate the parking demand per housing size of public-sized apartments, and to prepare that with the architectural regulations about parking supply. According to the results of this study, the parking demand of the small size housing unit(exclusive size：60 $m^2$ below) shows 1.09 car per the unit. and that of the medium size housing unit(exclusive size：60 $m^2$ over 85 $m^2$ below) shows 1.34 car per the unit. The parking demand of the small size housing unit was exceeded 56% more than the legal supply limit, and the parking demand of the medium size housing unit was exceeded 34% more. It is means that the level of architectural regulation about parking supply was not enough than the parking demand. So, it needs recon-sideration about the architectural regulations of parking supply.

With the economic development centering on large cities, apartments have been established as universal housing forms in Seoul and Shanghai. The deepening of economic development in cities has increased small households consisting of one or two persons by affecting the population and household structure, and they've become information consumer groups. This has also influenced the size of apartment and increased the demand for small-sized housing. If the floor area is small, it is possible to use space widely according to the plan composition, so there is a need for floor planning to understand natural environment, physical environment and residents.This study compared and analyzed plan compositions of small-sized apartments which have been parceled out for the recent three years in Seoul and Shanghai. This study aims to understand housing cultures and users in the two countries depending on natural environments, living habits and spatial functions by analyzing common points and differences of public spaces like living room, dining room and kitchen, and private spaces like bedroom which have absolute effects on room arrangement and traffic line. The study results are as follows. From the perspective of natural environments, in Seoul, two-sided open cross-ventilation structure where is favorable to lighting and ventilation, occupied the biggest proportion of public space, while in Shanghai, most public spaces had lighting and ventilation structures through windows in each room. In Seoul, 3R type occupied the largest proportion of private space(87.7%), and privacy was maintained and space scale was adjusted using spaces with diverse functions such as bathroom in the couple bedroom, dress room and powder room and variable walls. But 2R type occupied the largest proportion of private space(60.2%) in Shanghai, and they emphasized private space and privacy of each room depending on major living habits. In conclusion, this study for comparing and analyzing common points and differences of small-sized apartment plan compositions in Seoul and Shanghai will provide proper guidelines for small-sized apartments to be built in Seoul and Shanghai in the future, if strong points and weak points of plan compositions in the two countries will be additionally analyzed and remedied.

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.

The questionnaire survey was carried out from $19^{th}\;to\;22^{nd}$ of May 2004, with respondents consisting of 160 households living in two apartment complexes of Cheongju. Their residency periods after moving in were within $six{\sim}ten$ months. From the survey results of the respondents, sick house syndrome items revealed high percentages with the highest value of 49.3%. The respondents answered that they knew relatively well about sick house syndrome but they had no knowledge about 'bake-out'. The response percentages of sick house syndrome items in E complex, consisting of $106m^2$ (32 pyeong) size units, were significantly higher than those in A complex, consisting of $76m^2$ (23 pyeong) size units. This result suggests that the pollution levels emitted from interior materials in larger sized apartment units are higher than those in small sized units.

The purpose of this study is to investigate the actual usefulness and consciousness of bathrooms and to clarify the preference of bathroom plans by apartments dwellers in Jeonju City. Data was collected through self-administered questionnaires and 343 apartments dwellers were used for this study. The major results are as follows. The bathroom types were mostly unit bathrooms and were not suited with using bathrooms of apartments dwellers. The unit type of bathroom was not comfortable for them and most of them were not satisfied with their bathrooms. They usually used family bathroom instead of private bathroom. They wanted a separate space for different facilities such as a bathtub and toilet, a dressing room, and a fixed clothes chest. Generally apartments dwellers did not prefer unit bathrooms, prefering instead the bathroom plan with separate rooms for the bathroom and toilet, with space for dressing. This study suggests that further studies be conducted on apartments dwellers in other big, small and medium-sized cities. Also, it is necessary to offer bathroom plans which take the size of houses and bathrooms, and the number of bathrooms into account and to survey housing consumers' satisfaction of those bathroom plans.
