Abandoned high priced roads become functional links : Sky Garden, also known as Seoul Road 7017, commemorates the date of the original building and the completion of the renovation. It is also a representative and experimental work of the city's transition from "car-friendly" to "pedestrian-friendly". The original cement structure was reinforced by necessary elevators, staircases, escalators and other facilities to connect the ground. These bridges also connect commercial buildings, which increase their value by spending money. Other uses, such as coffee shops, performing spaces, supermarkets and so on, are well distributed.

Both a park and a botanical garden: Designed to provide the public with a living dictionary containing some of Seoul's native Korean species, they are now being moved downtown. We want to connect city dwellers with nature, and at the same time provide an excellent view of the historic Seoul Station and the South Gate. All plants are native Korean species and are distributed in Korean alphabetical order. The type of plant corresponds to its distribution and use.

Create entertainment venues: Varieties of trees, shrubs and flowers combine to turn air-polluted highways into green recreational walkways. A viaduct near Seoul's main site is designed to make the city, especially the traffic center, greener, friendlier and more attractive, while also linking up the green space around it.
