As the per capita personal income is increasing and residential buildings in cities are high-rising, resident’s concerns on living conditions are increasing as well. Recently, reflecting these trends, related acts and ordinances are keeping changing and litigations by residents are also increasing. Permitted development density in residential area has a great influence in people’s daily life.
Enacted in Jan. 2003, 「Act on planning and use of national land」 stated that residential development should observe the carrying capacity of infrastructure. But, until now, scientific method to find out an optimum development capacity is not established. Throughout the continual research, endeavors to prepare a planning guidance on development density is required.
Development density permitted by acts and ordinances in cities has an influence on citizen’s quality of life. There are important factors, such as supplement and maintenance cost of infrastructure, housing type, volume of environmental pollutants, traffic capacity, land price, daylight, privacy, ventilation and noise.
Optimum residential density, substituted by floor areas ratio, can decrease the conflicts among social classes, mitigate the infrastructure deficit or overcapacity and prevent conflicts among land use, In a community level, it can create walkable neighborhoods, support housing choice and affordability, expand transportation choices, support community fiscal health, improve security and protect the environment.
Unfortunately, research to create an optimum residential density has focused on individual factor, such as daylight or outlook. This research has focused on process to choose the optimum residential density and stressed on a collaboration between cities and social classes.
Chapter 1 Research outline
First of all, this study want to clarify factors influencing on residential development density and establish relative relations among factors. To prepare for a rational criteria on residential environment, literature review and interview on residents and professionals are performed. Secondly, by viewing the scope of reasonable development in simulation, professionals can utilize this study as a reference when they decide on the development density.
Based on previous studies related with development density, The factors influencing residential development density can be divided into three categories. In the midst of them, a level of residential environment was divided into more detailed criteria again and summarized by previous literature. Intensive research on Japan’s case is performed because it is insufficient and quickly changing factors. In addition, this study surveyed preference on residents and professionals to elicit a desirable criteria. Finally, the study performed computer simulation according to target of individual factor elicited by survey and suggested a desirable floor area ratio as a final result.
Chapter 2. Concept of development density and influencing factors
As a index to indicate development density, various criteria, such as population density, dwelling unit per acre, open space ratio, road ratio and floor area ratio, can be utilized. But floor area ratio is the more adequate method than any other one in calculating infrastructure capacity or building mass and evaluating an impact on living conditions. Debates on optimum development started in Europe of 1920s and trials to find out an maximum development density in korea are keep going.
