Tangshan South Lake Park was once a part of the Kailuan mine, an area rich in natural formations for extracting coal sediment for a period of more than 130 years. Today this area has been transformed into the focal part of the Tangshan Horticultural Exposition. Coal mining has become a thing of the past, and now instead a shimmering crystal-like building stands here.
Tangshan, a city in which coal and steel are central to the identity of the area. Moreover, a city that rebirthed itself after the shock of the earthquakes that struck the city. Sunlay Design Group hopes that through the World Horticultural Exposition, a presentation window to the wider world, it may be possible to create a botanical pavilion as part of the World Horticultural Exposition that embodies the history and culture of the city, and which may garner a high degree of recognition. This feature is the main exhibition hall for displaying the most important plants from the park, and it also functions as an integrated science education base and assembly point for international exchange, viewing pleasure and firsthand experience.

As the project site was characterized by coalmine collapses, the design team used “natural sections of ore” as their design inspiration. The team applied modern design principles and created a correlation to the existing site, applying geometrical abstraction to the structures and reinterpreting them. In addition, the team utilized the connections and planes of each surface in conjunction with comparisons of different materials, combined with the unique aspects of plant cultivation and the needs of viewers. In doing so, it was possible to provide the public with a genuine interaction and create a symbiotic plant display area. The environment surrounding the architecture furthers the folding plane elements of the external architecture, emphasizing the multi-dimensional extension of these textures. This was accomplished by utilizing the inherent height differences throughout the site through the use of walls, grassy slopes, steps, stands and pools. The use of design language was also an extension of these rich and abundant changes, such as the abstractly naming of the “Mountains and Rivers” activity park space.

The botanical pavillion is a 118 x125 meters long architecture that has an unusually curved, thin shell construction. The design of the structure ingeniously combines a glass curtain separation with a curved surface that rises and falls, which results in a naturally ascendant effect. By applying a method of using steel structure space to create a latticed shell, it was possible to achieve a ” crystalline ore” design concept. The World Horticultural Exposition Pavilion will cover an area of 3.54 hectares, displaying more than 1000 different types of plants. It is a project that is a combination of architecture, botany, ecology, architectural environment engineering, and aesthetics. More so, it is a calling card for the cultural promotion and internationalization of the city of Tangshan.

The layout of the architecture consists of four relatively independent exhibition spaces and a shared atrium. The exhibition space includes landscapes of a tropical rain forest, desert vegetation, flowers in all four seasons, orchid plants and other typical features. The exhibition area has an environmental management system that meets the conditions required for different plants, monitoring and adjusting the environment for plant cultivation and display conditions to ensure that an environment as close to its native conditions as possible is provided for the plant.

In response to the theme “City and Nature, Phoenix Nirvana”, which has been promoted by the World Horticultural Exposition, a vertical farm demonstration area has been set up in the venue. This has been proposed as a solution for the soil issues that are related to coal mining sediment in the area, and reveals the future developmental direction of agriculture.
