| Abstract |
This study aims to explore the background, purpose, and expected outcomes of the abolition of 'Diagonal Plane Control by Street Width (DPCSW)'. The methods of this study are as follows: (1) literature reviews with official documents and (2) empirical analysis and simulation with several sites located at a narrow street near Gangnam Station in Seoul. In conclusion, the abolition of DPCSW was intended to promote domestic real estate market, while lacking thorough scientific research. The simulation results show total floor areas in each building would effectively increase with the abolition and boost real estate market. However, the results also indicate without alternative design guidelines, the abolition of DPCSW can result in uncontrolled development with excessive urban density. Alternative urban design regulations such as Building Maximum Height by Block Unit and District Unit Plan should be extendedly applied to a wider area as soon as possible to prevent these issues. |
