(Background and Purpose) Korea is expected to reach super-aged society by 2026. More than 50 percent of the elderly over the age of 60 live in housing. In particular, caution is needed as 61.5 percent of elderly accidents occur within homes. In response, related standards are proposed to improve housing for the elderly. In response, Elderly-friendly standards are proposed to improve housing for the elderly. However, in housing, where the elderly reside, they face a planned problem that, deterioration buildings and the physical conditions of the elderly have not been taken into account at the initial design stage. In addition, it has been found that the size of housing is small, making it difficult to apply the housing standards for the elderly. The purpose of this study is to propose a plan for the elderly-friendly remodeling of housing and a plan for its application. It is believed that this will solve the problems of the elderly' safety and housing inconveniences that have emerged as social problems in the aging society and the use of aging housing. (Method) Through a comparative analysis of the criteria related to housing for the elderly in Korea, we identified the characteristics of each standard and problems with its application in remodeling. In addition, through analysis of the unit-space of housing, the plan for remodeling was derived considering the standard of housing for the elderly in Korea, and applied to the planning direction of elderly-friendly housing was proposed. (Results) The results of this study first, It is difficult to secure 1,500mm×1,500mm of wheelchair activity space in housing with a exclusive area of housing 59m². Therefore, 1,200mm×1,200mm was secured as an active space for walking assistance device. second, It is desirable to plan two bathrooms and approaching from the living room includes showering. It is appropriate to install a dry process washbasin and toilet and a well-waterproof holding door for shower booths. third, Balcony, which is difficult to secure an effective area of 1,200mm to 1,500mm, is advised to secure insufficient interior space through the expansion. fourth, Safety measures are installed as specified by the criteria, such as height-controlled furniture, handrail and slip-resistant finishing materials. It is appropriate to secure safety through the use of soft finish materials up to the height of handrail. fifth, For unit-space planning, it is appropriate to plan dead space as a storage space that is insufficient due to the securing of activity space. (Conclusions) A plan for remodeling of housing was applied to the unit-space that is continuously habitable in the current dwelling. This is expected to prevent safety accidents for the elderly and improve housing welfare.

Currently, public rental housing is biased toward quantitative supply of housing, and many factors that do not takeinto account the situation of tenants are emerging as social problems. The international community aims to achieve carbonneutrality to cope with global warming and climate change, and the need for eco-friendly materials and recycling methods isemerging in the construction field to reduce greenhouse gas emissions. This study proposes customized remodeling of publicrental housing using a modular method that can improve and revitalize the living environment of public rental housing andprovide smooth rental housing. First of all, customized public rental housing is a customized method that partially applies andremodels residential spaces, public spaces, and convenience facilities that reflect the needs of residents, unlike the existingremodeling method that is re-constructed after full demolition. In addition, the modular method is a type of de-site constructionwork, and it is possible to maximize air shortening and reuse the module by pre-manufacturing and transporting unit modulesto the site in a factory. Therefore, the urban housing problem, which is emerging as housing poverty for small households,requires a differentiated public rental housing supply method to cope with social changes such as lack of new housing,COVID-19, enforcement of the Severe Disaster Penalty Act, and carbon reduction through FM. Second, if residentialperformance is improved and expanded by remodeling existing public rental housing, it is possible to improve the settlementenvironment and supply low-cost and high-efficiency rental housing. Third, by using the modular method, it is possible todevelop a house tailored to consumers and compliant with social changes. It is proposed as a method that can quicklyimprove the residential environment and supply housing for public rental housing by constructing customized remodeling thatreflects the aforementioned demand of residents.

노후 공공임대주택 그린 리모델링 디자인 요소별 전문가 인식도 조사

최성경 ( Choi Seongkyung ),양소영 ( Yang Soyeong ),이문수 ( Lee Munsu ),문정민 ( Moon Jeongmin ) 한국공간디자인학회 2021 한국공간디자인학회논문집 Vol.16 No.8

(Background and Purpose) Since the ‘Green Remodeling Project’ is spotlighted as one of the 10 key tasks of the Korean Green New Deal policy, it has gained importance as a strategy for solving various problems to aging of buildings in Korea. Moreover, the building age of public rental housings has increased over 30 years since the public rental housings scheme started in 1990. Therefore, this study aims to explore design elements and evaluate the level of awareness of experts in various fields for achieving the goal of green remodeling by improving energy efficiency and the comfort of old spaces. (Method) Our research method was conducted in three major steps. First, the current status and problems of the overall project were identified based on previous literature and case studies related to the “green remodeling project for public rental housing” in Korea. Second, FGI (Focus Group Interview) with experts was conducted based on remodeling items analyzed through literature and case studies. From its results, remodeling items for each green remodeling design element for public rental housing were classified. Third, an expert survey was conducted to understand the level of awareness of experts in each field, based on the derived design elements and remodeling items. (Results) As a result of the FGI with experts, green remodeling design elements and remodeling items for the public rental housing were derived into 32 items in four parts: energy (8), space (10), design (8), and operation (6). In addition, as a result of conducting a survey of 72 experts based on the 5-point Likert scale to evaluate the importance of each element of the remodeling design, it shows energy (4.14) and operation (4.06) are more important than design (3.85) and space (3.94). And a result of evaluation on the specialized field shows urban regeneration, administration, housing welfare field (4.14) is more important than architecture, interior design, industrial design field (4.08), and energy and technology field (3.70). (Conclusions) In general, there have been various discussions on energy efficiency management and performance improvement of old buildings, and improvement of the quality of user-customized spaces. In order to solve this problem, various methods such as institutional change, promotion of new technology, and provision of welfare services, can be considered in each field. However, for sustainable and effective problem solving, it is necessary to explore interdisciplinary approach to new directions based on appropriate design elements for collaboration of experts from various fields.

세대수 증가형 리모델링에 대한 공법적 규율

김범준(Kim, Beumjun) 사단법인 건설법학회 2024 건설법연구 Vol.- No.11

리모델링 제도는 공동주택의 개・보수를 통해서 주거환경의 개선을 도모하고 무분별한 재건축사업의 시행을 방지하기 위해 도입되었다. 따라서 초기의 리모델링사업은 공동주택의 유지 또는 관리행위로서의 성격을 갖는 것이었고, 이후 사업을 활성화하기 위해 새로이 도입된 세대수 증가형 리모델링 또한 이와 마찬가지였다. 그런데 오늘날에 추진되는 세대수 증가형 리모델링사업은 마치 재건축사업과 유사하게, 사실상 새로운 아파트를 건축함과 동시에 주택단지를 전면적으로 개편하는 개발사업으로서의 성격을 갖게 되었다. 그럼에도 불구하고 리모델링사업은 주택법에 규정되어, 도시정비법에 따른 재건축사업보다 약한 공법적 통제를 받고 있다. 세대수 증가형 리모델링사업은 증가하는 세대수가 30세대 이상인 경우에는 주택법상 사업계획승인을, 그 미만인 경우에는 행위허가를 통해 사업 내용을 승인받는다. 행위허가는 건축물 관리행위를 규율하는 반면, 사업계획승인은 주택단지의 형성을 승인하면서 그 일대를 도시계획적으로 심사한다. 리모델링사업은 사업의 내용이 주택단지 전체의 존속에 영향을 미치는지 여부를 기준으로 유형화하여, 각각 별개의 제도에 따라 승인 기준을 마련하여야 한다. 현행법과 같이 증가하는 세대수를 기준으로 행위허가 대상과 사업계획승인 대상을 구별하는 것은 합리적인 것이라고 할 수 없고, 예기치 못한 규제 회피를 유발할 수 있다. 전통적으로 리모델링사업에서는 공사 완료 후 자기 소유 호실에 재입주하는 것이 원칙이었으므로, 주택의 소유권 변동이 거의 발생하지 않았고 따라서 사업 후의 권리를 배분하는 기준을 상세하게 수립할 필요가 없었다. 주택법은 세대수 증가형 리모델링사업을 추진함에 있어 권리변동계획을 수립할 의무를 부여하고 있지만, 권리변동계획의 수립기준 등을 상세하게 규율하지 못하고 있다. 그런데 세대수 증가형 리모델링사업이 점차 개발사업의 형태로 운용되면서 조합원의 권리변동 양상이 다양해졌고, 이에 권리변동계획의 내용에 따라 조합원 간 이해관계가 대립하고 분쟁이 발생할 가능성이 높아졌다. 리모델링사업을 통해 신축되는 건축물과 그 대지를 균형있게 배분하고 그 합리적 이용을 도모하기 위한 공법적 규율을 확충해야 한다. The public law regulations for remodeling projects were introduced to improve residential environments through the development and maintenance of multi-family housing, and to prevent low-quality reconstruction projects. Remodeling projects were initially focused on preserving and managing multi-family housing, and so did the “household-increasing remodeling,” which was introduced to activate remodeling projects. Notwithstanding, nowadays, household-increasing remodeling projects are more akin to reconstruction projects because they involve the reconstruction of new apartments and, simultaneously, a comprehensive reconstruction of housing complexes. Despite similarities, remodeling projects are governed by the Housing Act and subject to weaker public law regulations, while reconstruction projects are governed by the Act on the Improvement of Urban Areas and Residential Environments and subject to stronger regulations. To initiate a household-increasing remodeling project for increasing household numbers by 30 or more, it is necessary to secure project plan “approval”; if the household number increase is less than 30, it is necessary to secure a “permission”. The “permission” relates to building management activities, whereas an “approval” involves a comprehensive assessment of the residential area in light of urban planning. Remodeling projects are also examined differently based on whether they affect the entire housing complex. Still, distinguishing the procedure for project initiation based on the increase in household numbers may not be rational and can lead to regulatory arbitrage. Traditionally, remodeling projects involved minimal changes in property ownership because the residents came back to their remodeled houses. This led to less attention being given to post-project rights, and although the Housing Act mandates the establishment of a “plan to alter rights” for household-increasing remodeling projects, it fails to establish the details. As household-increasing remodeling projects are becoming more similar to reconstruction projects, the uncertainty has intensified regarding resident rights assignment. These uncertainties can lead to disputes among residents regarding the content of plans to alter rights. Currently, there is a need for more detailed legal regulations to enable the reasonable assignment of rights among residents regarding newly constructed buildings and their land. This can foster efficiency in the use of these buildings and land in remodeling projects.

주택법상 공동주택 리모델링과 환지에 따른 법률관계

신국미 건국대학교 법학연구소 2024 일감부동산법학 Vol.0 No.28

공동주택 관리 정보시스템에 따르면 2024년 4월 기준 국내 공동주택단지 수는 총 18,721단지로, 이 중 15년 이상 된 단지 수는 전체의 50% 이상에 이르고 15년이 경과된 공동주택은 매년 30만호 이상 증가하는 추세이기에 향후 공동주택의 노후도는 가속화될 것으로 예상된다, 현행 법제하에서 노후 공동주택의 정비사업은 30년 이상 경과된 공동주택을 대상으로 한 재건축사업과 높은 용적률로 인해 재건축이 어려운 공동주택에 대해서 행해지는 리모델링사업이 대부분이며, 현재 리모델링사업의 대부분은 세대증가를 수반하는 수직증축형 리모델링으로서 사실상 재건축과 유사한 형태의 리모델링이다. 본 연구는 1:1 리모델링과 달리, 세대수 증가형 리모델링의 경우 증가된 세대에 대한 대지사용권을 부여하기 위해 권리변동이 행해진다는 점에 착안하여, 세대수 증가형 리모델링에서의 권리변동 및 부동산 등기에 대한 사항을 다루었다. 1:1리모델링에서는 전유부분의 면적증감이 있더라도 대지지분의 변경이 없는 반면, 세대수 증가형 리모델링은 전체 대지지분의 조정 및 변경이 발생하므로 이에 관한 대지권변경등기가 발생하며, 증가되는 세대에 대해서는 일반분양이 이루어진다. 따라서 수분양자에게는 제한물권의 부담이 없는 구분소유권과 대지사용권을 부여하여야 하므로 등기상 소유권보존등기가 가능한지 여부를 검토하였다. 원래 리모델링 완성 후 부동산등기는 부동산표시변경등기의 형태로 행해지는 것이 실무의 관행이었으나 리모델링주택을 분양받는 수분양자의 입장에서 보면 소유권보존등기가 행해지는 것이 오히려 타당할 것이다. 그런데 리모델링 완성 후 구분건물에 대한 소유권보존등기를 하려면 기존토지대장 및 건축물대장의 폐쇄가 선행되어야 하므로 관련규정(공간정보의 구축 및 관리등에 관한 법률을 비롯한 관련법규정)에 대한 충분한 검토가 이루어져야 한다. 대장의 폐쇄 및 소유권보존등기 여부에 대한 자세한 검토는 후속연구과제로서 다루기로 한다. 끝으로 인구고령화보다 심각한 공동주택의 노후화 문제의 해결로서 공동주택리모델링방식은 재건축의 대안 또는 재건축과 동등한 위치에서 비중 있게 다루어져야 함에도 불구하고 그동안 우리의 관심 밖에 있었다. 본 연구를 계기로 재건축과 차별화되는 공동주택 리모델링의 정체성확립과 현재 건축법과 주택법 등 곳곳에 산재해 있는 리모델링 관련 규정을 통합하여 단독법률로서 리모델링 특별법의 제정을 제안한다. According to the apartment management information system, the total number of apartment complexes in Korea as of April 2024 was 18,721, of which more than 50% were 15 years old. Therefore, since the number of apartment houses that have passed 15 years is increasing by more than 300,000 every year, the deterioration of apartment houses is expected to accelerate in the future. Under the current legislation, the improvement project of old apartment houses is carried out in two ways. It is a reconstruction project for apartment houses that have passed 30 years or more, and a remodeling project for apartment houses that are difficult to reconstruct due to the high floor area ratio. Most of the remodeling projects currently being carried out are vertically expanded remodeling that involves an increase in households, and are actually similar to reconstruction. This study dealt with rights alteration and real estate registration in ‘remodeling to increase the number of households’ focusing on the fact that rights alterations are made to grant ‘right to use site’ to increased households, unlike 1:1 remodeling in the case of “remodeling to increase the number of households” In 1:1 remodeling, there is no change in land shares even if there is an increase or decrease in the area of section for exclusive possession, whereas in the remodeling with an increase in the number of households, the registration of a change in land rights occurs because the adjustment and change of the total land shares occurs, and general sales are made for the increased households. Since the general buyer must be given a sectional ownership and right to use site without the burden of restricted property rights, it was examined whether it was possible to register the preservation of ownership by registration. However, for the registration of ownership preservation, the closure of the existing ledger must be preceded. Therefore, a sufficient review of the provisions of related laws, including the Act on the Establishment and Management of Spatial Information, should be made, which will be dealt with as a follow-up research project. Finally, as a solution to the aging problem of apartment houses that are more serious than population aging, the remodeling method of apartment houses has been out of our interest until now, even though it has to be treated with great importance as an alternative to reconstruction or on an equal footing to reconstruction. It is proposed to establish the identity of apartment remodeling, which is differentiated from reconstruction, and to this end, to prepare a special remodeling bill as a single law by integrating the remodeling-related regulations scattered throughout, such as the Building Act and the Housing Act.

공동주택 재생을 위한 리모델링 계획요소 연구

고산화,한연오,박태원 한국부동산분석학회 2016 부동산분석학회 학술발표논문집 Vol.2016 No.-

우리나라의 공동주택 공급은 1970년대부터 시작되어 1980년대 중반 이후까지 1기 신도시가 건설되면서 대량으로 공급해 왔다. 이 시기에 건설된 공동주택은 20년 이상이 경과되어 노후화된 공동주택이 급증하면서 주택의 유지ㆍ관리 및 개ㆍ보수의 필요성 증대와 주택의 질에 대한 사회의 다양한 요구 변화로 주거환경개선을 위한 재정비의 필요성이 제기되었다. 이러한 상황과 함께 저출산 고령화 시대에서 신규주택수요가 급감하고, 주택가격의 안정과 사업비부담으로 재건축사업의 사업성이 악화되는 상황에서 노후불량 주택은 매년 30만호가 증가하고 있으므로 공동주택 리모델링은 선택이 아니라 필수적인 사업이 되고 있다. 또한, 새로운 신도시가 지속적으로 건설됨에 따라 기존의 신도시들은 상대적으로 낙후되어 가기 때문에 리모델링에 대한 기대감이 높아지고 있다. 이에 본 연구는 1기 신도시가 본격적으로 노후화 되면서 리모델링에 대한 필요성의 증대와 리모델링 사업 활성화가 예상됨에 따라 공동주택 리모델링의 계획기준을 선정하여 향후 진행될 공동주택 리모델링 사업을 위한 기초적 토대를 제공하고자 한다. 본 연구의 목적인 공동주택 리모델링 사업의 계획기준을 선정하기 위하여 국내외 공동주택 리모델링 사례를 분석하였으며, 시사점을 도출하였다. 선행연구에서 논의된 공동주택 리모델링 사업의 고려사항과 시사점을 종합하여 예비변수를 선정하였다. 이후 도출된 예비변수를 중심으로 부동산, 건축, 단지계획 등의 관련 분야 전문가를 대상으로 표적집단면접법(Focus Group Interview)를 실시하여 변수의 위계 및 적합성 여부를 검토하였다. 이를 통해 공동주택 리모델링 사업 계획요소를 도출하였다. The supply of apartment houses began in 1970`s, and the 1st stage new town was constructed until mid-1980`s to be supplied in mass-scale. The apartment houses constructed in this period is now over 20 years since they were constructed, and due to the rapid increase in deteriorated apartment houses, the necessity of reorganization is brought up for improving the housing environment due to the increase in the necessity of maintenance and repair of houses and changes in various requirements of the society on the quality of housing. Along with these conditions, the demand for new housing is rapidly decreasing in the low-birth & aging period, and the business feasibility of the reconstruction is worsening due to the stabilization of the housing price and burden of reconstruction cost. Each year, approximately 300,000 deteriorated and defective houses are increasing, and remodeling of apartment houses is now not an option, but an essential project. In addition, as new towns are continuously being newly constructed, the existing new towns are relatively being falling behind, therefore, the expectation on remodeling is increasing. Therefore, in this study, as the 1st stage new towns are being deteriorated to increase in need for remodeling and as the activation of remodeling business is expected, the remodeling planning standard of apartment houses is to be selected to be provided as the basic foundation for future apartment house remodeling projects. To select the purpose of this study of planning standard for the apartment house remodeling project, domestic and foreign apartment house remodeling cases were analyzed, and implications were derived. The considerations and implications on the apartment house remodeling project that were discussed in advanced studies were gathered to select the preparative variables. Then, with the preparative variables that were derived, the focus group interview was conducted to experts in the fields of real estate, architecture and complex planning to review the hierarchy and conformance of the variables. Through this, the elements of the apartment house remodeling project plan were derived.

박성식,박윤재,김명식 대한건축학회 2022 대한건축학회논문집 Vol.38 No.7

The study aims to derive and organize factors that determine remodeling types involving LH aged long-term public rental housing. Relevant remodeling legal system, precedent research, LH internal data to figure out the overall remodeling content, various statistics and press releases were reviewed and analyzed to find factors that determined remodeling types. The determining system regarding remodeling direction and types were divided into three steps. Steps one and two entailed maintenance remodeling and units supply remodeling; step three involved renovation, vertical expansion, horizontal expansion, residential area expansion, and annex expansion to determine the detailed types. The first and second phases were set by population changes such as elderly population increase and urban change known as population increase, business increase, and old buildings increase. As for the third phase, it was set by an apartment complex's status in terms of the number of people waiting to move in, spare floor space ratio, spare building-to-land rate, tenant’s characteristics, and structural safety diagnosis grade. Overall, this study proposed determinants organized into three phases that should enable the identification of a remodeling type suitable for LH aged long-term public rental housing. 본 연구는 LH 노후 장기임대주택의 리모델링 유형을 결정하기 위한 요인들을 도출 및 체계화하는 것을 목적으로 한다. 연구방법은 리모델링 전반의 내용 조망을 위한 리모델링 관련 법제도 검토, 선행연구 분석, LH 내부자료 검토, 그리고 유형 결정요인을 찾기 위한 각종 통계자료나 보도자료 등의 조사 및 분석으로 이루어진다. 마지막으로 찾아낸 결정 요인들을 단계별로 체계화하여 리모델링 유형을 논리 및 합리적으로 결정할 수 있도록 정리한다. 연구결과는 차례대로 다음과 같다. LH 노후 장기임대주택의 리모델링 방향을 설정하는 1~2단계(세대수 유지형 리모델링과 세대수 증가형 리모델링)와 세부 유형을 결정하는 3단계(대수선, 수직증축, 수평증축/전용면적 확장, 별동증축)로 구분된다. 전자의 1~2단계는 각각 인구변화(고령인구증가)와 도시변화(인구증감, 사업체증감, 노후건축물증감)이고 후자의 3단계는 단지현황(입주대기자수, 여유용적률, 여유건폐율, 세대특성, 구조안전진단등급)이다. 최종적으로 본 연구는 제시된 1~3단계의 결정요인들을 통해 LH 노후 장기임대주택에 적합한 리모델링 유형을 찾을 수 있을 것으로 결론짓고 있다.

공동주택의 친환경 리모델링을 위한 부품 인터페이스맵에 관한 연구

임석호 대한건축학회 2005 대한건축학회논문집 Vol.21 No.12

Recently, Domestic construction industry is confronted with a new phase by increasement of stock and elation of the concern about environment. In particular, the focus on remodeling as an altanative of the reconstruction system that squanders resources and creates massive construction waste, has increased. However, current remodeling methods are being obstructed factor, because design has not considered the remodeling at the beginning of the construction. From the environmental point of view, the reconstruction of the existing apartment houses and overall remodeling cannot solve all the problems.Up to this time, the remodeling has been approached from the limited point of view and the repair-centered remodeling has not been discussed as a process that precedes remodeling. In addition, as the use of a long-term repair plan is so rare, overall structures need to be checked by using a comprehensive maintenance system that operates in conjunction with routine maintenance and repair and remodeling according to the concept of the hierarchy and zone in the future. Breaking away from the conventional notion of a long-life house that refers to a house that simply lives long, this study redefined it as a house to which zone and hierarchy concepts are applied with its main components provided with the system for the remodeling such as Interface Map from the design /contruction/maintanance manual.

공동주택 세대구분 리모델링 계획방법에 대한 연구

전영준(Chun, Young-Jun),하미경(Ha, Mi-kyoung) 한국주거학회 2016 한국주거학회 학술대회논문집 Vol.28 No.2

The population structure of South Korea is changing recently because of low birthrate, aging and an increase in one-person households. In order to accommodate that chages, The Divided Housing(Partial Rent Dwelling System House) was invented for making full use of living space and creating additional revenue. But the actual construction has been low, and there"s a limit to supply through new construction only. So, the purpose of this study is to define the concept of Divided Housing Remodeiling, which can change existing large-size apartments to dividable house, and to suggest reasonable method of it with remodeling simulation. The findings of this study are as follows : 1) The essential elements of Divided Housing Remodeling is separate entrance, bathroom and kitchen, which can be derived from the preceding research and actual constuction examples of Divided House. And the planning process of Divided Housing Remodeling can be suggested by determining priorities of those elements. 2) In this study, the planning process of Divided Housing Remodeling is used to simulate the representative type of old large-sized apartments in metropolitan area, and it is possible to suggest recommended alternatives of that.

공동주택 리모델링 사업타당성 평가를 위한 수익/비용 예측 모델

김완혁(Kim, Wan-Hyuk),차희성(Cha, Hee-Sung),신동우(Shin, Dong-Woo),김경래(Kim, Kyung-Rai) 대한건축학회 2013 大韓建築學會論文集 : 構造系 Vol.29 No.4

Most Aged-Housing Remodeling Projects are going with little expected profit lacking in certain types of index or standard for decision making. Due to the lack of knowledge for the remodeling, lack of profit caused by official disapproval for the vertical building extension, limitation of space caused by the existing building structure, unprofessional business subject and delay of remodeling business, the aged-housing remodeling market in korea have not been activated. Due to the slowdown in the remodeling industry with lack of relevant data, there is a shortage of research for evaluating profit and cost of aged-housing remodeling projects. In this study, the authors suggest that aged-housing owners can take advantage of the early decision-making process in terms of feasibility and Profit/Cost Prediction Model on aged-housing remodeling. For this purpose, literature review and interviews with experts in remodeling factors affecting profit and costs are analyzed. Based on this analysis, the evaluation items and criteria are established. Through case studies and multiple regression analysis, profit/cost prediction model for aged-housing remodeling projects is proposed using Hedonic price modeling method.
