地區單位計劃 인센티브제도 實效性에 관한 硏究 : 마포지구 사례를 중심으로

마포지구 사례를 통해 지구단위계획 인센티브제도의 실효성을 분석했다.

영문초록:The incentive of easing the uniform floor area ratio not taking into consideration the local characteristics was imposed on all the matters of building restriction in four new urban design districts designated in the Mapo district. The design of most building structures in the Mapo district has progressed in a direction of admitting the existing situation and did not feel the necessity for receiving the incentive such as the floor area ratio and the like even by providing the public-use land.

This situation is the problem pointed out as in most other urban design districts, and because most districts form the density of development that does not arrive at the standard floor area ratio in case of the urban design district and detailed plan revolving around life or the life zone, it can be seen that there are many cases that the incentive of the floor area ratio indeed exists as one system but is not implemented. If the floor area ratio increased due to the incentive system of the floor area ratio as in the case analysis of the Mapo district, it was found that it led to better economic efficiency than the project to which the current legal floor area ratio was applied.

Tis is because the benefit that developers acquired through the application of the incentive was higher than the cost that they spent to get the incentive applied. In case of the officetel in Dongkyo-dong, building the officetel building for the allowed use would lead to better economic efficiency than when the incentive is not applied. But this is because the area of the officetel building to be sold by installment increased due to the increase of the floor area ratio.

It would be necessary to consider even loss and profit arising from the rate of installment sale because the neighborhood life facility not really well sold by installment within Dongkyo-dong was built for the recommended use. But in case the incentive is all applied, the area of installment sale for the officetel not well sold in Dongkyo-dong increases. For this reason, it would be better to build the officetel building under the application of all the incentives than under the application of the incentive for the recommended use.

Like this, building owners should seriously examine economic efficiency and cope positively with it, not thinking that the provision of public-use land in the form of contribution is a harm to them
