노후주거지 재생을 위한 소규모 블록 단위 건축 계획 연구

Abstract

As South Korea has experienced rapid urbanization and industrialization since the 1960s, the housing shortage has intensified with cities at the center. The new concept of multi-family housing in 1984 and multi-family housing in 1990 was adopted to solve the housing shortage through the high density of housing sites. However, it has developed into a policy and a social one, focusing only on the quantitative supply of housing. Rapid development without taking into account the characteristics of residents and regions has caused many problems with the residential environment. Quantitative developments in a uniform form, excluding local characteristics and living conditions suitable for residents' lives, revealed weaknesses such as the occurrence of gentrification and the dissolution of communities. In addition, high-rise apartments and multi-generation and multi-family houses were spread in single-family housing complexes, resulting in lack of parking space, lack of green space and invasion of privacy as single-family housing complexes were developed that were not considered along with qualitative factors and land use. Although the national housing supply rate has exceeded 100% since 2010, measures have been needed due to aging as the ratio of elderly housing units over 20 years has exceeded 57%. Especially, as social conditions have changed greatly, such as changes in values, income improvement, and technological development, the need for various housing readjustment has begun to emerge.

As a result, in 2017, the government announced a bottom-up New Deal policy. The New Deal project aims to overcome the limitations of existing urban renewal techniques and improve living conditions for local people, not large-scale redevelopment.

In this study, we intend to overcome the limitations of the existing reconstruction and redevelopment with the small block unit master plan through the introduction of the building agreement, raise the need for a gradual and sustainable small block unit master plan for residents, and explore ways. In addition, the purpose of this study is to review the blockage unit development obstacle elements in the study site, to propose the alternative of small block unit master plan, and to propose new possibilities for small block development through objective evaluation and verification.

Therefore, the chapter of this study consists of: Chapter 1 first describes the background and purpose, scope, method, composition and flow of this study. Second, based on the pre-survey review, it is derived from the need for research on the status of aged and defective dwellings and the need for practical measures to improve the environment in small block units.

Chapter 2 investigates laws and systems related to old residential areas as a theoretical consideration to identify trends in residential development and to understand current understanding of obstacles to housing regeneration projects and autonomous building activities in self-development or readjustment in old residential areas. Second, taking into account the theory of block-by-block housing development, the concept and necessity of block-by-block housing development to improve old residential areas and restore communities. Third, as a theoretical consideration of the architectural convention that can overcome the obstacles of autonomous development and maintenance of old residential areas, the necessity and possibility of building agreement are derived and the limitations and complementary points through case analysis are reviewed.

Chapter 3 analyzes the status of the target site, and reviews the regulations of written units to derive the need for the development of block units.

Chapter 4 sets out assessment items to objectively evaluate the direction of planning and alternatives of housing plans for each block based on the need for housing development by block as derived in Chapter 3. In addition, three types of block-unit master plan alternatives are proposed and three kinds of alternatives are evaluated according to the existing status and assessment items.

Chapter 5 draws a comprehensive conclusion from this study.
