The objective of this study was to identify ecological environment elements that may be introduced in creating urban apartment complexes and to suggest possible options on how to introduce them. To this end, a questionnaire survey has been mailed to 120 residents-to-be of apartment complexes to suggest ecological environment elements and techniques preferred by residents-to-be and, accordingly, they have been applied to study areas. The detailed results of this study are as follows. (1) Introduction of diverse plant species instead of plantation using grasses only and considering the height and density of planting adequately appeared effective in enhancing ecological diversity as well as visual preference. (2) Creation of eco-ponds using rainwater was one of the most desirable options in urban apartment residential complexes. Also, eco-ponds can increase visual preference when they are arranged through adequate vegetation management. (3) The results showed that when creating habitats for such as insects using porous space, it is desirable to consider a visual aspect first and then to create habitats for various insects. When the results of this study are actually applied to a real study area, it will be able to increase ecological diversity in urban apartment complexes as well as raising visual preference. Accordingly, it should be introduced proactively in planning, designing, and creating real apartment complexes.
