The following research has been conducted in order to analyze the effectiveness in the aspect of real estate of the previously implemented policy under the notion that the Crime Prevention Through Environmental Design(CPTED) could secure the self-perpetuation of a region and maintain a sustainable crime prevention environment. Thus we examined the current status of “Crime Prevention Through Environmental Design Project” that has been proceeded for 5 years by the city of Seoul, analyzed the impact of application of CPTED to real estate transactions and the results are as follows.
First, the operation and maintenance for the CPTED projects seems to be well functioning according to the site investigation. Surveillance cameras and emergency bells are widely placed so that it can be recognized by the local citizens easily, and the signs that notifies the project is in progress were seemed to be handled very well. However, it was hard to find any other elements for crime prevention other than the surveillance & report system, and Safety Maru, the only facility was being used in wrong ways such as gardening and private gathering purposes for the local residents. For this a variety of plan elements are ought to be utilized apart from the monotonous surveillance & report system, and it is believed that the Safety Maru should serve its original purpose.
Second, the analysis of the effects of CPTED Project in Seoul shows that it affects the city in a positive way. The criminal rate of the regions with the implementation of the project was relatively diminished, therefore, it was obvious that the project is reducing the number of crimes. Also on the real estate transactions on the following region, every 12 examples showed increase in the amount of transactions which makes the plans to draw the effect by the CPTED region following this particular trend necessary.
Third, despite the decrease in the crime rate the residents responded that the area is not safe according to the survey. This seems that the project could effect the decrease in crime rate due to the active application of wide Surveillance & Report system, but its influences fall short to the extent where the residents actually feel safe in their area, which requires us to improve the project in the aspect of the urban regeneration which ultimately leads to active real estate transaction in order to implement the recognition of safe residential environment. To achieve this we believe a multilateral approach in terms of architecture/urban/real estate is necessary, with the ultimate goal of realization of self-sustainable urban space.
Fourth, the local residents responded that the residential area does not feel safe even after the institution of CPTED project in seoul, but it is investigated that they still wish to move to the region with the implement of following project in case of making decisions on moving in the future. This result is thought to be the reflection of people's expectations that the project could be improved with trial and errors over time, along with the actual decrease in crime rate.
Fifth, it is shown that the actual impact of the CPTED project to the decisions on real estate transaction is rather minimal, therefore, a variety of attempts to realize the sustainable crime prevention project other than just the surveillance & report system seems necessary, which is going to realize the construction of self-sustainable and safe environment if the region is vitalized and when it affects the decisions on real estate transactions.
