The officetel introduced into Korea in the mid-1980s has thus far been in the limelight as the object of investment for the substitute for small-sized housing and for lease income. But to raise the possibility of succeeding in officetel investment in the future, it has been necessary to make a systematic analysis of the changed direction of the officetel market and the profitability and stability of investment. Accordingly, this study attempted to analyze demand for officetel with a focus on the possibility of increase in the households composed of one or two members, the major consuming bracket of small-sized housing. And it attempted to analyze the possibility of investment in officetel as the investment goods for lease income due to the entry of Korea into aging society. And past analysis of investment in officetel was confined to profitability analysis, but this study sought to develop the stability indicator of the officetel for the analytical purpose. As a result, it is predicted that demand for small-sized housing will increase due to the increase in 1-to 2-person households. Accordingly, it is predicted that demand for officetel as the place of residence will come to increase. And taking into consideration the more serious degree of sustained aging in the population, older people's preference for real estate and need for lease income, it is predicted that preference for officetel as the object of investment will increase. An attempt was made to analyze the profitability and stability of investment in the metropolitan area which the officetel has principally been supplied, in order to analyze the profitability and stability of officetels. For the purpose of this study, Yeoksam-dong in Kangnam-gu, Yeoui-dong in Youngdeungpo-gu, Bongcheon-dong in Kwanak-gu were selected in Seoul as the area for analysis. Jung-dong in Wonmi-gu, Bucheon, Seohyun-dong in Bundang-gu, Seongnam, Janghang-dong in Ilsan-gu, Koyang were selected in Kyonggi province as the area for analysis. As a result, it was found that the small-sized officetel had higher profitability and stability than the large-sized officetel. It was found that the area of Kyonggi Province had the larger deviation by size. That is, it was found that the small-sized officetel in the area of Kyonggi Province was significant as the object of investment for stable lease income.

본 연구는 부산지역 오피스텔의 가격을 결정하는데 있어서 영향을 주는 요인들이 어떤 것들이 있는지에 대해 실증적 분석을 하여 오피스텔 시장을 구체적으로 이해하는데 목적이 있다. 시세가를 통해 오피스텔 가격 결정요인을 분석하는 것은 오피스텔 공급자로 하여금 적절한 규모와 입지선택에 도움을 줄 수 있고, 수요자들에게는 목적에 따른 오피스텔 선택에 도움이 되리라 판단하여 본 연구를 실시하였다. 부산지역 오피스텔의 실거래가를 종속변수로 하고 물리적 특성과 입지적 특성, 그리고 지역적 특성을 나타내는 요인들을 독립변수로 하여 OLS선형회귀분석(Ordinary Least Square)과 준로그모형분석(Semi-log model), 그리고 로버스트회귀분석(Robust regression)을 이용하여 오피스텔의 가격결정요인을 분석하였다.

1980년대 중반 오피스텔이 처음 공급된 이래로 오피스텔 건축기준이 변화함에 따라 오피스텔의 기능은 사무용에서 주거용으로 변화되어 왔다. 서울시의 오피스텔 공급추이를 살펴보면, 1991년에 상대적으로 많은 공급이 이루어졌고, 1990년대 중반에는 공급이 감소되었다가, 1596년 이후 다시 증가 추세를 보이고 있다. 서울시 오피스텔의 임대료 결정 요인에 관한 회귀분석을 실시한 결과, 강남 여부, 전용률, 주거용 여부 등의 설명변수들이 서울시 오피스텔의 주요 임대료 결정요인으로 나타났다. 따라서 서울시 오피스텔의 평당 임대료는 강남에 소재하고 전용률이 높으며 주거용인 오피스텔이 그렇지 않은 것에 비해 높다는 것을 알 수 있다. 또한 사무용 오피스텔의 경우에는 층수가, 주거용 오피스텔의 경우에는 전용률이 유의한 결정요인으로 나타났다.

본 논문은 대표적인 수익형 부동산인 오피스텔의 효율적인 관리방법을 도출하기 위하여 수요와 공급이 가장 밀집되어 있는 강남구 테헤란로를 중심으로 관리 만족도 설문조사를 통해서 오피스텔 관리의 문제점을 파악하고 오피스텔의 용도, 소유 호수, 소유기간 등 세 가지 가설을 검증한다. 설문조사 결과에서 도출된 오피스텔 관리의 문제점은 크게 제도적 미비와 관리주체의식 부재로 나타나고 있다. 본 논문은 오피스텔의 단편적인 투자 가치적 분석에서 벗어나 실제 소유주들을 대상으로 내 외부적 관리 문제에 밀접하게 접근하여 관리에 대한 비용적인 측면 뿐 아니라 제도적인 측면의 해결방안을 검토한다.

Recently, risk analysis studies regarding the architecture development project have been carried out by applying probabilistic method. However, it had a limit that this studies was conducted in only an apartment. Therefore, the objective of this study is to develop an optimal price estimation model that can be utilized on residential officetel project by applying Monte Carlo simulation. To achieve the objective, first, the variables are selected affecting the feasibility of an officetel based on literature review. Second, causal loop diagram is constructed by arranging the relationship between variables, then the import and expense model is suggested. Third, to carry out optimized parcel price, the range limits are set for each variables then Monte Carlo simulation is performed. In the future, the developed model is expected to help decision-makers as a tool to determine both risk and feasibility of the officetel development project.

The purpose of this study was to suggest the improvement plan for IAQ of the combined officetel and residence through analyzing demands, satisfaction, subjective symptoms and device of residents. For this study, the data was collected from 110 residents by questionnaire survey and an experienced planner by interview. The result showed that the IAQ improvement of the combined officetel and residence was urgent. The educational program about maintenance of IAQ for residents was essentially needed. To recommend eco-friendly materials in process of construction wasimportant so as to take precaution against ‘sick building syndrome'. It was also necessary to improve on the size and shape of ventilation window.

The purpose of this study was to suggest the idea for IAQ improvement of the of officetel which is used by fully or partly residential space. The data was collected from 110 residents by questionnaire survey and an experienced architect by personal interview. The results showed that the IAQ improvement of the officetel with residential usage and residence was urgent. The educational program about maintenance of IAQ for residents was essentially needed. To recommend eco-friendly materials in process of construction was important so as to take precaution against 'sick building syndrome'. It was also necessary to improve on the size, shape, and location of ventilation window.

The domestic construction industry is changing its preference for demand and supply along with urbanization and economic development. Accordingly, initial risk assessments is more important than before. Currently, the research related to risk analysis except for apartment studies is insufficient. Therefore, the objective is to suggest a basic study on financial analysis model development by applying optimization method in residential officetel. To achieve the objective. first, the previous studies are investigated. Second, the causal loop diagram is structured based on the collected data. Third, the financial model is developed by using optimization method. In the future, the proposed model can be helpful whether or not conduct execution of an officetel development project to the decision makers.

Recently, in Korea, single- or two-person households (50.5%) are becoming the primary family type due to increasing divorce rates, population aging, personal code of values and so on. Hence, small families will lead to a sudden increase of single- or two-person households. People searching for small houses are increasing because of the provision of officetels, one room and urban-life housing as well as economic recession. However, this has led to habitability problems, such as parking, storage space and decline in safety. In this study, we obtain the proper contents from LQI indicators of advanced research and use the indicators to evaluate the residential environment quality. We conduct a post-occupancy-evaluation (POE) survey and compare the habitability satisfaction level of apartment and officetel residents. According to the survey, officetel residents' satisfaction levels are low for the following factors in the order listed: ventilation, storage space, management expenses and facilities for children and the elderly.

In response to the economic depression, the demand for fixed rent income has increased according to the easing construction regulations. it caused indiscriminated investment to stakeholders. This leads to oversupply in the multi-family Housing market and increases unsold housing and vacancy rates except specific area such as Gangnam-gu.In order to solve this issue, although studies on the optimization price of apartment houses has been conducted, the study is insufficient regarding on residential officetel. Therefore, the objective is to suggest a basic study on optimal price estimation model development by using probabilistic forecasting method in planning phase. To achieve the objective, first, variables are defined such as expenses, financial costs, income, etc. Second, causal loop diagram is suggested. Third, basic optimization prices estimation model is developed. In the future, this study can be used as one of decision making tools in planning phase of officetel development projects.
