The design is based on the geometrical relationships of the basic hexagonal unit which is composed of three different units. The three geometrical units; trapezoid, parallelogram, and equilateral triangle share their dimensional relationships in both their lengths and heights; which result in careful geometric combinations among them. Through diverse possible combinations, the basic units can create diverse but changeable street furniture complex, which creates undulating profiles resembling  an undulating nature of Seoul city.
