Shenzhen Bay "Super City" international competition, 3rd Place

Third Prize: Superposed city
The vitality of Shenzhen depends on his strong capacity of innovation and absorption. In the future, Center of the Shenzhen Bay “Super City” will be built 150-170 million square meters, in which about 6-7 million people will work. In this case, could we make a different imagination to meet the requirements of the development sustainable of the future?
With the issue, turning to history, we found a skyscraper comic in New York in1909, in the skyscraper, people want reproduce everything on the ground: each floor has its own land and sky. This prompts us to conceive a city in the air that needs urban space and big green garden. The imagination utopian maybe brings something for the future skyscraper in Shenzhen.
The Superposed city concept:
The concept of the Superposed City introduces the urban space, public transportation and other urban elements to the high-rise building. This will erase the limit between the architecture and city. The Superposed City will be an integration of variety urban functions and improve public facilities to meet the daily needs of people.
The project integrates the different urban spaces and creates a unique form in respecting height limit of city planning. We space several horizontal ring-like volumes superimposed with the large circle green gardens in the air (30-50 meters high and up to 1200 meters the perimeter). The annular volumes form a huge city atrium. The openings of different sizes bring the air and light into the city atrium.
In organizing the circulations of the Superposed City, we establish a vertical public traffic system: people can take a kind of “vertical bus” (huge lift cage with three levels) that connecting the subway to reach the middle and top garden in the air, and then transfer the internal elevators to each level of building.
In differing from traditional mode of produce and consumption of energy, the Superposed City itself will be a generator. There is a huge energy body in the air, it contains an inexhaustible supply of energy and water, wind and solar omnipresent.
In the Superposed City, the epidermis of construction is the ideal place to generate clean energy. Wind power generation device (wind belt generator) and photovoltaic power generation device are scattered on the epidermis, in absorbing maximally the environmental energy. The Superposed City can self-suffice for its power consumption. With the development of technology, the rate of energy conversion will be greatly improved. In the future, it will provide the power to the nearby urban area, in playing an important role: generator of city. In the Superposed City, the rainwater and water in the air can be collected and recycled.
The space design of the Superposed City brings itself into a huge air conditioning device. It provides natural ventilation suitable to inter spaces to make it less dependent on the air conditioning equipment, thereby reducing energy consumption. The air convection will be produced naturally by the height of huge City atrium and the difference of temperature inside and outside of city. In adjusting and filtering the air, the green gardens in the air can control the air temperature, humidity, cleanliness and wind speed and form a comfortable outdoor environment.


Entry Prize of Dalseong citizen's Gymnasium, Award

The site of Dalseong citizen’s Gymnasium is located at Dalseong-gun of the Daegu Metropolitan City. Between mountains and river, the natural environment of site is characterized by wonderful landscape around. The old gymnasium building will be demolished; while we preserve the memory monument.

To planning the project of Gymnasium, we connected different parameters: topography, accessibility and program. The fusion of these aspects was highly important for the concept definition- to conceive the building as an installation on the landscape.

The topography is crucial in our decision since we had to deal with an enormous difference (about 14m) between the levels of the roads around the site. A landscape carpet replaces the existing platforms of the site. This continuous space smooths the elevations in recovering the characteristic of the environment.

Lifting the carpet, we found the entrance public of gymnasium on the same level of the interior of the building. Like walking in the mountain, following the curve of carpet, we arrive at the top of this topography. Here, we create a platform, a roof terrace, belvedere -the stage scenario is the huge and impressive landscape with mountains and plain along the riverside. At same time, the roof terrace will be considered as exterior spaces for cultural activities and for leisure. A parking space with 52 places will be founded its entrance on the Hyeonpungjungang-ro. To make the Gymnasium becoming one element of the Dalseong sport Complex Park, a bridge is dragged over the Hyeonpungdong-ro on the north of the site.

We enter in the building, accompanying natural light introduced gently from the slits, without feeling the limit between exterior and interior. The glazing wall offers an interior panoramic view. Lights and activities are shared for all people in the building. 436 Audiences seats could be installed for the badminton courts. A ramp connects the roof terrace and interior space.

Roof structure will be a honeycomb steel system laying on the structural glazing, permitting a maximum space flexibility, natural light and ventilation. By installing the program in heart of terrain, we could reduce the energy consummation.

Three scenarios (environment landscape, roof terrace, interior space) permeate and fuse each other by installing this landscape carpet.
