In the domestic housing market, uncompleted lot-solid apartments and unoccupied residences are increasing in the medium-large scale area whose rents and transactions have been unstable, as going through the financial crisis and economical recession. Demands for small-scale housings are steadily increasing by practical consumer group who don't need large places, which are often not needed for the current people who are spending most of their time outside of their houses. Therefore, this study proposes the useful methods for spatial planning for small-scale houses for multiple households, including variable form, levels form, multi-level form, and smart-sizing. For efficient spatial planning for that purpose, here, small-scale housings are not limited to places for families with 1-2 members, but considered as one of broader approaches to graft various households and families. In addition, we examined the existed trends of researches about spatial utility of small-scale places, and did the research about the status of small-scale housing developments, and then proposed the direction for future small-scale housings by analyzing the advanced examples.

England's green belt policy as it delivered its framework to designating the development restriction zones(DRZ) in Korea is the key to address issues which try to change green belt boundary or/and housing development. Therefore it should necessarily be reviewed on the understanding of how England has been formulating a national policy to deal with the issues focusing on opportunities for housing development and recreation. This study explored the discourse and framework of England's green belt policy as well as driver changes of housing development and recreation. Results show several characteristics of England's green belt policy which are civil society consensus on conservation and management, limited small-scale housing development through management of release rates, a systematic procedure for application and approval, open-recreation space expansion and utilisation under the premise of conservation of natural green areas, and management structure by the involvement of NGO organisations. Therefore, five suggestions can be delivered to developing Korea's DRZ frameworks: first, preceding social consensus on the preservation value of development-restricted zones, second, addressing housing shortages in different alternatives e.g.) environmental-friendly small-scale housing, third, institutionalising the total proportion of release, fourth, establishing an open-recreation space, fifth, introducing expanded public-private partnerships. Ultimately securing the legitimacy of the nation's development-restricted zone system can contribute positively to the environment preservation and human health by promoting public leisure activities in terms of the recent increase in external activities caused by the Covid-19 crisis. Concluding remarks are here that the understanding of England's green belt policy can be delivered to and help formulate domestic policy addressing current issues.

본 연구에서는 IMF 경제위기 이후 서울의 아파트 가격이 지역에 따라 양극화 되는 현상을 거주지 분리 심화라는 틀을 통해 분석하고자 한다. 이를 위해 서울의 지역별 아파트 가격 차별화와 고학력집단의 거주지 분리 정도를 밝히고, 아파트 가격과 고학력집단 거주 비율의 상관관계를 밝히고자 한다. 연구 결과 거주지 분리와 아파트 가격의 차별화라는 공간적 과정은 밀접한 관계를 맺고 있는 것으로 나타났다. 서울시 행정동을 단위로 45$\sim$59세 인구의 고학력집단 비율을 시계열적으로 분석한 결과 1990년에 이미 현재와 같은 학력집단별 거주지 분리가 관찰되고 있어, 거주지 분리가 지속적으로 재생산되고 있음을 알 수 있다. 행정동별 고학력집단 거주 비운은 아파트 가격의 행정동별 변이와 밀접한 관련을 보이고 있다. 1997$\sim$2003년 사이 아파트 가격의 상승은 고학력집단이 공간적으로 집중되어 있는 지역을 중심으로 발생하였다. 그외 지역의 아파트 가격은 정체되어 있거나 소폭의 상승을 보여 아파트 가격의 지역차가 매우 강화되었다. 아파트 가격의 지역별 차별화는 거주집단에 따라 지역이 달라지는 거주지 분리 과정을 적극적으로 반영하고 있다.

최근, 미국에서 발생한 주택담보대출시장 비우량대출 부실로 인한 세계 금융위기에 따라, 우리나라 주택시장 또한 침체를 겪고 있다. 이에 대한 대응으로 정부는 주택 수요 활성화를 위한 다양한 규제 완화 정책을 시도 하고 있다. 특히, 주택담보대출비율(LTV) 및 총부채상환비율(DTI) 와 같은 주택담보대출 기준의 완화를 통해 주택수요 및 주택 거래의 활성화를 기대하고 있으며, 2차 주택담보대출시장을 활성화하여 주택 수요의 지속적인 발생을 유도하고자 한다. 그러나 이러한 정책은 비우량 대출 부실로 시작된 세계 금융위기에 역행하는 시도가 될 수 있다. 이러한 상황에서, 시장에 대한 예측은 대부분 단편적인 시각으로 이루어지고 있어, 향후 주택시장의 변화에 대한 종합적이고 체계적인 예측 방법론에 대한 필요성이 대두되고 있다. 따라서 본 연구는, 주택시장 및 주택담보대출시장을 구성하는 기본 요소를 바탕으로 통합된 관점의 주택시장 시스템다이내믹스 연구 모형을 작성한다. 또한, 연구 모형을 통해 정부의 주택담보대출 규제완화가 시장 참여자에 미치는 영향을 알아본다. 이는 수요 자극을 통해 침체된 주택시장의 주택거래 활성화 효과를 기대하고 있으나, 제 2 주택담보대출 시장의 형성 및 부실 파생상품 생성 가능성을 높일 위험을 갖고 있다.

공동주택 PF 부실사업장의 증가는 사업참여 주체인 시행사 및 시공사의 부도뿐만 아니라 금융사의 경영악화로 이어져 장기적으로 경제 전반을 악화시키는 악순환을 형성하고 있어 빠른 정상화가 요구되고 있다. 이를 위해서 많은 대안이 제시될 수 있으나, PF가 우리나라 부동산 개발 시장의 한계 속에서 개발된 금융기법인 만큼 금융시장과 자기자본 건전화 등 구조적 개선을 빠른 시일 내에 이루기에는 한계가 있다. 이에 현실적으로 조속한 정상화를 위해서는 대형시공사의 부실사업장에 대한 투자결정이 필요하다. 그러나 대형사공사와 투자를 원하는 시행사 및 금융사의 투자결정에 관한 중요도 인식에 차이로 사업이 무산되는 경우가 있어 본 연구에서는 각 사업주체별 공동주택 PF 부실사업장에 대한 투자결정시 시공사, 금융사, 시행사인 참여주체별로 고려하는 주요 투자결정요인의 도출하고 요인별 중요도를 비교분석하였다. 나아가 투자 결정요인 중요도 도출을 통해 부실 사업 참여 타당성 평가 모델을 수립하고 실제 사례에 적용함으로써 모델의 현실 적용성을 검증하고자 하였다. 전문가를 대상으로 한 AHP 분석 결과 1계층 중요도는 대형 시공사의 경우 사업성> 토지매입리스크, 분양성> 인허가> PF> 시행사 리스크인 것으로 나타났으며 2계층은 분양가의 경쟁력> 사업수익률> 사업부지 확보율> 사업기간>토지비상승 가능성인 것으로 나타났다. 이러한 결과는 시행사와 금융사의 중요도와 차이가 있는 것이며 대형 시공사의 투자결정요인 중요도 모델을 실제 3가지 유형의 투자사례에 적용해 본 결과 실제 투자결정 결과가 일치하여 적용성도 있는 것으로 나타났다.

Purpose - This study investigates the following two issues. First, we attempt to find the important determinants of housing investment and to identify their significance rank using survey panel data. Recently, the expansion of global uncertainty in the real estate market has directly and indirectly influenced the Korean housing market; households demonstrate a sensitive reaction to changes in that market. Therefore, this study aims to draw conclusions from understanding how the impact of financial strength of the household is related to house investment. Second, we attempt to verify the effectiveness of diverse indices of financial strength such as DTI, LTV, and PIR as measures to monitor the housing market. In the continuous housing market recession after the global crisis, the government places top priority on residence stability. However, the government still imposes forceful restraints on indices of financial strength. We believe this study verifies the utility of these regulations when used in the housing market. Research design, data, and methodology - The data source for this study is the "National Survey of Tax and Benefit" from 2007 (1st) to 2011 (5th) by the Korea Institute of Public Finance. Based on this survey data, we use panel data of 3,838 households that have been surveyed continuously for 5 years. We sort the base variables according to relevance of house investment criteria using the decision tree model (DTM), which is the standard decision-making model for data-mining techniques. The DTM method is known as a powerful methodology to identify contributory variables for predictive power. In addition, we analyze how important explanatory variables and the financial strength index of households affect housing investment with the binary logistic multi-regressive model. Based on the analyses, we conclude that the financial strength index has a significant role in house investment demand. Results - The results of this research are as follows: 1) The determinants of housing investment are age, consumption expenditures, income, total assets, rent deposit, housing price, habits satisfaction, housing scale, number of household members, and debt related to housing. 2) The impact power of these determinants has changed more or less annually due to economic situations and housing market conditions. The level of consumption expenditure and income are the main determinants before 2009; however, the determinants of housing investment changed to indices of the financial strength of households, i.e., DTI, LTV, and PIR, after 2009. 3) Most of all, since 2009, housing loans has been a more important variable than the level of consumption in making housing market decisions. Conclusions - The results of this research show that sound financing of households has a stronger effect on housing investment than reduced consumption expenditures. At the same time, the key indices that must be monitored by the government under economic emergency conditions differ from those requiring monitoring under normal market conditions; therefore, political indices to encourage and promote the housing market must be divided based on market conditions.

At the economical crisis of Korea in 1997, self-determined price for apartment and the revision increasing the ratio of residential area for mixed-use residential building were introduced to activate the construction industry, which causes construction companies to build super high rise apartment discriminative and high class orientated. This study aims to classify the super high rise building which is planned to build or built recently and to analyze the architectural characteristics. The objects are 288 unit households in 26 apartment complexes higher than twenty five story since 1998. As a result, super high rise building comparing with existing apartments were being varied in plan types of main building and unit household and in construction types. As for the plan, the number of walls having opening to outdoor were increased and it is considered that high rise building can take advantage of a view, lighting and sunshine. The location of living room that used to be in the center of unit in existing apartment was moved freely without rule.

The purpose of this study is to examine the regional differences of 0-12 aged children's environment based on their parents' socioeconomic class and on the character of the settlement. One thousand and two hundred households were investigated and the results are as follows. It is revealed that families in low socio-economic class are more likely to be exposed to noise and home crowdedness. Families living in spontaneous settlement are deprived of natural light and the roads to their homes are steep and narrow. Low income families face a housing affordability crisis. Most of them pay housing rent on monthly basis. The basic infrastructure of low income neighborhood is lacking convenient facilities like shopping centers, public transportation systems, banks, public parks, and libraries. This lack of facilities is more severe in spontaneous settlement. Instead, bars and taverns are located in their neighborhood. Accessibility to parks and resource centers is an important factor that makes both middle and low income families consider their neighborhood to be positive and this condition is counted better in social housing area than in spontaneous settlement. On the contrary, social networks like friends and relatives are strong in spontaneous settlement and families in poverty value these relationships. Such networks are weak in social housing area and this difference is not related to their residential period. Low income families living in social housing area are more pessimistic about their future and this view might result from their counterpart middle class neighbors and the weak social networks.
