Fractal waves expand topographical features of the eastern coastal area architecturally . It connects the middle part of complex coastline topography composed of mountains and rocks with gentle curvature to artificial nature. The gentle curve from the mountain leads to the coastline and ups and downs, providing maximum ocean views to all hotels and condominium units while providing a private outdoor terrace area. Inter-spaces that increase in curvature are used as public areas. As a result, fractal waves merge into the surrounding context with the geographical characteristics of the Dongbu mountain and become part of the natural landscape.
