The purpose of this study is to investigate the changes of housing characteristics and the degree of attainment of housing norms. The major findings are as follows: 1) There are significant differences in changes of housing characteristics. A size of house and the number of room have been improved according to hosing experience and housing expects. Type of tenure has been improved according to housing experience and housing expects. Type of tenure has been improved gradually according to moving. The family with higher socio-economic status prefers apartments. Although about a half of household hopes to live in a high-rising apartments. more than 40 persentage of the household still hopes to live in single detached houses. As a result apartment are though not to satisfy their housing well-being 2) As socio-economic status is higher and family life cycle is longer the degree of their attainment of housing norms appear higher. The household attaining higher housing norms has the higher housing satisfaction but needs to move is lower The family attains housing norms as the following orders: type of tenure\longrightarrowtype of house\longrightarrowthe nmber of rooms\longrightarrowa size of house.

To investigate opportunities for wood frame housing and to activate wood frame house construction, trends of construction activities. preference about housing, and building codes related to wood frame housing were discussed. And two models of wood frame house were developed and construction cost was analyzed to compare with comparative masonry houses. The results obtained were as follows: 1. While 77.8% of people prefer single-family houses, majority of people(74.9%), ironically, possess multi-family houses such as apartments Wood work cost was ratio of 4% of total building cost. while wood material cost accounted merely for 11 % out of total building material cost. 2. Building code was not major barrier to residential house at height under 13m. The building code regulated major structural member and family boder wall of multi-family house to be built with fire retardant material. 3. The proper wood frame house was analyzed of town house or villa type locating in suburban of big city with hot ondol system for the upper middle class. 4 There was no difference in construction cost between western style wood frame house and comparable masonry house, but construction cost for Korean style wood frame house is 27% higher than that of comparable masonry house. It was necessary to reduce materials and cost down by prefabrication technique for both style of wood frame house.

This comparative study on the confucian characteristics of the space for men on the upper-class house took two approaches. Firstly, even though Korea and China accepted same Confucianism, they developed their own Confucian cultures and differentiated house types. Therefore, the process of developing various type of house can be observed as to adopting Confucianism. Secondly, identification of each country can be appeared by looking into the house developing process. Preceding studies about traditional houses of Korea and China usually focused on style analysis. However, this study approaches to house arrangement through understanding the base of each culture and people.

The aim of this study was to determine the basic perception of Kleingarten house planning of Jeonbuk area. The survey method was used for data collection. The major finding were as follows: 1) Almost all respondents have a very positive attitude the participant of Kleingarten. Many respondents wanted the cheapest price for the Kleingarten rental fee and for the travel time between their home and Kleingarten to be under an hour. 2) Two different size of 45 and 66 $m^2$ were preferable for the house floor plans. The most preferable floor plan type chosen by the respondents was a house design with a terrace and the elderly householders especially preferred a house floor plan with an LDK design. 54.3 per cent respondents liked the log house and 93.3 per cent respondents liked the eco-friendly building materials such as wood, earth (Korean natural earth: whangto), and adobe bricks etc. 3) There were more needs for useful facilities such as a pergola, a grassy lawn, small ponds, a playground for the childrens, patio table settings, etc.

In the past thirty years, apartment house has been greatly developed and the housing supply has improved some degree. However, the fact is that interior space planning of apartment house still has a lot of problems. The purpose of this study is to research the change of interior room. The 160 examples of unit floor plan(40-85m2 i.e. 12.1py-25.7py) were selected and classified according to master bedroom type and living room area when was constructed by the city of Seoul and KNHC from 1970 to 1990. And then, the change of each area, size and ratio were analyzed and researched. The result of this research can be summarized as follows: 1. Size of unit floor plan was on the increase from 16.02py to 17.86py. 2. 2 bedroom type, master bedroom showed a rise of size and occupancy ratio. Living room grew larger than 1982-1991 for size and occupancy ratio. 3. 3 bedroom type, master bedroom was increased in size and occupancy ratio was reduced to 19.99%. Size of living room became broader than master bedroom and occupancy ratio(1972-1981) increased over 1982-1991. Through this analysis and research, this study is to provide the basic data for actural design process and to suggest future trend of apartment house.

The purposes of this study were to investigate the state of indoor thermal and air environment during winter in the one-room type multi-family houses occupied by university students and to analyze factors which influenced this environment. Field survey was conducted in 10 houses between 30th January, 2009 and 13th February, 2009 which measured indoor thermal and air elements as well kept records of interviews with residents and other related factors. Measured elements were air temperature, relative humidity, as well as concentrations of $CO_2$, CO, TVOC, and PM-10. The results can be summarized as follows. 1) The mean air temperature in each house ranged from 19.3 to $25.3^{\circ}C$, so most houses were not suitable for evaluation criteria($20-22^{\circ}C$). The average $CO_2$ concentration in each house was 965~3259ppm, so most houses exceeded evaluation criteria(1000ppm). The average TVOC concentration in each house were 0.00~1.17ppm, 5 houses exceeded evaluation criteria(0.12ppm). 2) Relative humidity, CO concentration, and PM-10 concentration were suitable for evaluation criteria. Therefore, indoor thermal and air environment during winter in one-room type multi-family housing occupied by university students was found to be generally uncomfortable. Important factor which were found to influence air temperature and the concentration of $CO_2$ were smaller space capacity than general house. Other factors which were found to influence the environment of these houses were the existence of a balcony as well as factors relating to the behavior of occupants such whether or not heating were operated, whether windows were opened, whether fans used, whether occupants smoked or used cosmetics, and whether the space was dusted.

In this study, it was analyzed that, the way of securing publicity and privacy in family and type of public space of the Japanese contemporary detached house, by the composition type of family from one person home to four generation family home. Mostly the living room is made as open plan of LDK type. Mostly, the entrance hall is separate with living room. Even if the case of the entrance hall is connected with living room, it is planned to be recognized as entrance hall, by making entrance poach or connecting it with stair hall. In many case, the public space is designed as traditional Japanese style, such as wellhole style space (吹拔け), courtyard, and Japanese style room (和室). The Japanese style room is adjacent to living room, and used as the space of receiving guests. The wellhole style space and courtyard are recognized as the center of the house, and used as buffer space for ensuring privacy of each generation. The most different point between bachelor house and multi generation family house is another LDK space, living room or kitchen for parents' generation is made separately. Particularly there are many case of making separate small kitchen space, therefore it can be known that, the separation of kitchen space is recognized more importantly than that of living room. And there are many case of making separate entrance hall, two houses under one roof. The spatial composition like this can said as rational method of ensuring the privacy of each generation, and using the public space together as necessary.
