The motif of the agricultural exhibition hall is taken from the barn of Chinese agricultural civilization. Its appearance is like a square box, the internal core is a circular silo, which means "square barn and round granary". It not only implies the legalist concept of "When the granaries are full, people follow appropriate rules of conduct, and when there is enough to eat and wear, people know honor and shame", but also conforms to the construction of spiritual civilization in the new era.
The building maximizes the footprint of the barn and excavates a blowing space in the center. The circular silo is introduced with natural lighting and ventilation. As a seed Museum, it provides a place to display and communicate; The rotating open stairs connect the various functions in the vertical direction of the building. The visitors step up, just like stepping on a seed journey, and their desire for viewing and exploration is constantly stimulated.
The mortise and tenon structure of the silo dispels the divinity of the space with the color and touch of old wood, making the barn warm and amiable. The two sets of indoor and outdoor stairs form a parallel viewing moving line, overlooking the pastoral scenery, surrounding buildings and internal activities of the agricultural exhibition hall.
The outer skin is made of UHPC material. This material with low porosity is as warm as jade, which can highlight the shape and lines of the building itself. From a distance, it has sharp edges and corners, and from a close look, it is soft and hazy. The faint sense of permeability blurs the boundary between the building and the environment. It forms a visual contrast with the glass curtain wall, which vividly explains the relationship between enclosure and connection, closure and permeability.
