The purpose of this study is to identify the characteristics of the Dressing-Room lay-out in brand-apartments as the strategy for the differentiation. The 441 floor-plans are collected by searching web-sites of the 5 main construction companies. The major findings are summarized as follows: (1) The Dressing-Rooms are designed in the 331 cases among 441 the floor-plans including the Dressing-Room are generally over 30 Pyeong(about 99 square meters). In addition, the entire cases above 60 Pyeong(about 198 square meters) include the Dressing-Room. (2) The size of the Dressing-Room is increased in proportion to the square meter. However, the ratio is the small range of fluctuation. (3) The types of Dressing-Room units are classified 4 categories : a dressing-room joined powder room, a dressing-room separated from bathroom, a dressing room without powder room, a powder room centering with dressing room and bathroom.

Purpose: Condensation in walk-in closets attached to apartment bathroom has been known as an emerging issue that may threat occupants' comfort and health. Despite a number of design guidelines and enforcements to prevent condensation, condensation issues may still occur depending on various cases and scenarios. We aim to identify what condensation scenarios may lead to walk-in closet condensation and/or worse the existing condensation issues. Method: First we choose an actual walk-in closet of an apartment that suffers from sporadic condensation and resulting mold and mildew. Then we observe its relative humidity and temperature after the bathroom is used, in which excessive vapor is thought to be transported to the walk-in closet. We analyze Temperature Difference Ratio - a domestic indicator of condensation occurrence, and dew point temperature to compare it with surface temperature using 2D heat transfer simulation upon various condensation scenarios. Result: TDR of the test walk-in closet turns out be OK despite mold and mildew actually occurring. Hot water pipe installed in the floor would greatly reduce condensation. If hot water pipe in the upper floor, however, is not used, or hot water pipe of the closet is turned off during swing seasons, it is expected that condensations may still occur.

Housing construction companies have been providing master bedroom walk-in closet as a selling point in modest sized apartments as small as 74m$^2$. It is noticeable that master bedroom walk-in closet in apartments provided by public sectors showed much variety in its size. This study tries to set up the guide line of master bedroom walk-in closet size. It is quite reasonable to assume that the biggest space-occupiers in walk-in closet are blankets and clothing. The survey conducted in this study shows that the number of clothes people keep in their closet does not show any significant difference regardless of square footage of their apartments. 34.7% of respondent answered they keep about 50-60 clothes using coat hangers, where 20-30 of those are winter clothes. It is calculated the required optimum length of the walk-in closet is 3.8m$^2$. Considering the most popular longitudinal dimension of master bedroom, 3.9m, and the space needed to accommodate blankets, it can be concluded that the required length of storage in master bedroom walk-in closet is 2.1m. The length can be adjusted reflecting the length of the master bedroom.

The authors developed a nodal network model that simulates the flow of moist air and the thermal behavior of a target area. The nodal network model was enhanced using a parameter estimation technique based on the measured temperature, humidity, and schedule data. However, the nodal model is not good enough for predicting humidity of the target space, having 55.6% of CVRMSE. It is because re-evaporation effect could not be modeled due to uncertain factors in the field measurement. Hence, a data-driven model was introduced using an artificial neural network (ANN). It was found that the data-driven model is suitable for predicting the condensation compared to the nodal model satisfying ASHRAE Guideline with 3.36% of CVRMSE for temprature, relative humidity, and surface temperature on average. The model will be embedded in automated devices for real-time predictive control, to minimize the risk of surface condensation at dressroom in an apartment housing.

The purpose of this study was to find out the characteristics of the floor plans of luxurious row-houses. The examined objects were 135 floor plans with the individual exclusive space of 50 pyung or more which collected from the solicitations for sale or the magazines of architecture, housing, or interiors. The major findings were summarized as follows: First, it is revealed that as the floor size become bigger, the appropriate additional spaces such as second family room, lounge hobbyroom and Atelier are formed instead of increasing room size. Second, it is revealed that the L- DK type was the most common in LDK system. Third, it is revealed that the master's zone composed generalized layout of 4 sections such as bedroom, sittingroom, bathroom, dressingroom. Fourth, it is revealed that the multifunctional room exist as a individual space located next to the kitchen. It used to be a post of rear balcony.

The purpose of this study was to suggest optimum guidelines apartment rooms by conducing survey among residence whose apartment floor size is between $66-198m^2$ and whose apartment is less than 3 years old. The effective numbers of survey questionnaire turned in was 226 and the survey analysis has been made by using of SPSS WIN 12.0. The results and conclusion of the studies are as follows; (1) $66{\sim}98m^2$ : The recommended numbers of bedroom is 2 and 3. The size of maser bedroom needs to be decreased whereas the size of living room be increased. (2) $99-131m^2$: The recommended numbers of bedroom is 3 and 4. The size of maser bedroom and maser bathroom needs to be decreased whereas the size of living room, 2nd bedroom, kitchen and dining room needs to be increased. (3) $132-164m^2$: The recommended numbers of bedroom is 3 and 4. The size of maser bedroom and bathroom needs to be decreased whereas the size of dress room, kitchen and dining room, and 2nd bedroom needs to be increased. (4) $165-197m^2$: The recommended numbers of bedroom is 3 and 4. The size of maser bedroom and maser bathroom needs to be decreased and the size of dressroom and kitchen /dinning room needs to be increased. (5) $198m^2$ and above: the recommended numbers of bedroom is 3,4 and 5. The size of dressroom needs to be increased. It is revealed that the number of bedroom doesn't need to be increased as the size of apartment is increased. Larger space is required for the public space for the family and dressroom. And smaller space is required for the maser bedroom and master bathroom.

The study analyzed the effects of the floor plan characteristics on the apartment price under the national housing size in 3 Gangnam districts for decades, the primary apartment markets in Korea. The analysis showed that the storage spaces such as kitchen, warehouses and dressage rooms have a positive effect on the price. Especially, the highly opened space with three-side open plan and the one with the unified type of livingroom, diningroom and kitchen have shown the strong effect on the price. For the kitchen spaces, the I-shaped kitchen tends to be more expensive while a centered living room has a positive effect on the price. These findings have an academic significance as the direct effects of plan characteristics on price has been examined unlike prior research focused on the analysis of trend, basic statistics, and satisfaction level. It is noteworthy that these research finding has identified the productive implication for the future floor plan design and pricing and also be implemented in the purchasing decision making by buyers in the housing market.

Recently, the proportion of single-person households is on the increase in Korea, expected to reach 34.6% in 2035. Among the single-person households, Young single family households are facing greater difficulties due to high house prices in Korea. The government is expanding its support to Young single family, executing various policies such as public lease housings, private lease housings for youth, youth dormitory, etc. The purpose of this study is to understand the exact housing requirement of Young single family households who have different lifestyles with other age groups and provide base line data for youth house planning which will be in use later on. Study methods are shown below. First, this research studied the status and characteristics of Young single family households by looking into literature. Second, by studying previous studies concerned with life style and housing preferences of youth, the tool for investigating preferences and needs of housing environment by Young single family households was composed. Third, survey on characterstics of space usage, preferences and needs on flat composition, and preferences of interior design were conducted based on lifestyle of Young single family-households. The survey was conducted as an online survey using SNS for 150 Young single family holds from the age of 20 and 39, including students and office workers from December 2018 to January 2019. The results are as following. (1) Looking into the space usage characteristics, considering that various activities other than basic functions take place in bedroom and living room of small-sized Young single family households, we need to consider this additionally when planning the housing. (2) Looking into the preferences and composite needs of flat composition, the subjects demand separate bed room and more living room space, and also demand expansion of living room space where various activities take place and additional storage such as dress room in bed room (3) The preferences toward interior design show preferences toward modern style and achromatic color, a representative color. The subjects also prefer floor finishing materials normally used for living spaces, and indirect, soft lighting that uses wall. Also, there are differences between interior design preferences between students (20's) and office workers(30's) due to their different lifestyles. Research is needed to propose practical residential environment requirements and plans through a case study of actual public rental housing and a wider range of users.
