In the context of China's rural revitalization, with the rapid development of rural tertiary industry in the ecological era, more and more rural industrial relics have been produced, which urgently need to be updated and activated to integrate into the industrial upgrading of rural areas, become a new attraction point, attract new industries and entrepreneurial populations to gather here again, show the youth and vitality of the future countryside, and thus become a new focus to enhance the competitiveness of rural areas.
The "two mountains" concept, which states that "green water and green mountains are golden mountains and silver mountains," was first proposed in Anjiyu Village in Zhejiang, the location of Yucun Impression. The two structures were formerly a part of Yucun Weishan Industrial Park. The area has now been turned into farmland, demonstrating how Yucun has evolved from a "industrial bird" to a "ecological pastoral" in green development. Yucun Impression is China's first carbon-neutral building, completed in June 2022. The structure has multiple uses, making it the most active and creative rural area.
"Yucun Impression" revitalizes a defunct rural industrial structure, incorporates it into the ecological era's growth of rural regions, and demonstrates the open and inclusive development mindset of China's rural areas against the backdrop of rural rehabilitation strategy.
Yucun's worldwide cooperation initiative is attracting an increasing number of young people. The arrival of young entrepreneurs has resulted in a clash of rural and urban cultures in Yucun, altering the traditional way of life. The characteristics of rural public buildings are also quietly evolving; they are no longer just for villagers, but require buildings with more integrated services and cultural notions that are more inclusive. As a result, the Yucun impression is positioned as a youth library, with the hope of developing it into a complex and inclusive cultural site where villagers, young entrepreneurs, and tourists may find cultural resonance.
About 480 square meters of the structure were originally used as a cement plant, a structure created for the manufacture of cement. The second building is the former silk production workshop, which has a two-story interior and a steel roof truss. The two little, 100 meter-distance, need-renovation buildings are close together.
Architectural renovation design must find its original element characteristics from space, form, and material, and give the two buildings unique appearance characteristics through reorganization and innovation of architectural language, as well as strengthen the dialogue and connection between the two isolated buildings. Simultaneously, the site and its surrounding natural features are involved, so that the rural industrial architecture and the local natural environment merge, completing the memory penetration from the site to the structure.
Starting with the location, the designers created a low-impact land theater on the existing site to recreate the lost collective memory of the countryside by man and nature. The cultivation of crops on the land is similar to the land use of the original factory building, and the transportation route of the original factory building is preserved, and people are looking for memories of the development history on the road while studying the history of Yucun. While visiting, people can participate in the production and harvest of crops, which can make people and nature have a deep resonance.
The most intuitive vehicle of communal memory is form. The architectural renovation design adheres to the maxim "minimum intervention, maximum benefit," extracts and retains the inherent formal memory of the original building, incorporates these memories into new scenes, and realizes the sustainable protection and renewal of the building by using the most intuitive form as the medium of collective memory.
In architectural renovation, we focus on retaining the original cultural memory while giving more possibilities to the space. The cement factory retains the volume of the original building and the memory of the windows opening, and the upper part of the building is made more transparent so that the architectural space can integrate with the mountains, which is a metaphor for Yucun’s transformation from a cocoon to a butterfly.
On the glass façade, the outline of the original building window is outlined with a metal window frame that highlights 40 cm, a metaphorical memory window, adding functionality to the space. The triangle staircase is preserved in its original form on the north façade, which has hairy bamboo replacing the encased concrete envelope to create the best viewing platform and reduce obstruction of the surrounding landscape，while serving as a staircase for fire evacuation.
The two inside walls of the former cement plant have been turned into library bookcases from the ground floor to the top floor. As a result, the structure becomes an open, continuous space with books running through every corner, serving as a cultural and educational hub for the community. High bookshelves and stairs create a dynamic gathering space for tourists, locals, and new youth to read, talk, and communicate.
The original vast space structure is preserved in the rebuilding of the original wire drawing plant, and the original openwork exterior wall is replicated using lightweight perforated aluminum plate material to promote the permeability of the internal and outdoor space. The structure maintains its open spatial layout and is designed as a rural exhibition hall area of the library, which serves as a display location for Yucun.
To establish communication and connection between the two buildings, the designers constructed a sunken plaza that connects the basement of the former cement factory building. The plaza can act as a public gathering place for people to unwind, congregate, and perform between the two buildings as well as guide traffic from the square to the basement level.
The supplementary corridor connects the two buildings in series, making the two originally isolated buildings connect, lessening the impact of the height difference of the site on the building, and building a complete pedestrian flow line. In this way, an overall connection between buildings and roads, farmland and the terrace is established, and the overall site space is activated. The corridor also becomes a dynamic corridor for site interaction. The corridor can also be used for visual attraction and communication functions, improving the overall image and visual impact of the building, making it a site landmark, and providing space for the show.
Yucun impression material is a rebirth of the industrial era's memory. Local bamboo is used as a model and poured with concrete to make bamboo mold concrete, which is used as the major material for the building's wall. The external staircase and corridor rails are built of hairy bamboo from the mountain, creating a textural appearance that matches the bamboo molded concrete.
The advancement of technology and materials has resulted in zero carbon emissions, as well as the exploration and practice of the future development direction of rural zero-carbon construction.
The photovoltaic glass component is installed on the building's roof, and the electricity generated is used to power the opening of the glass curtain wall. Solar collectors are mounted on the roof, and the heat generated is used for solution regeneration in the dehumidification system. Ventilation shafts are installed on the bookshelves to provide hot pressure ventilation using a combination of ventilation and wind pressure ventilation.
Following the building's reconstruction, the Youth Library and the National Comics-themed Coffee Shop opened, became the most popular destination in Yucun. Tourists, young people, children, and relaxing residents congregate here. Continuous use keeps building spaces changing. Designers monitor the building's business needs and update the building's spatial components on a regular basis to assure the project's sustained use value.
While operating in Yucun Scenic Area, various cultural and creative activities are regularly held here, including Yucun Global Partners, Youth Forum, Comic Photography Exhibition, Year-end Bonus Conference, Midi Music Festival, etc., attracting a large number of young tourists.
These two industrial heritage buildings have been fully integrated into the operation of Yucun Scenic Area, becoming the most active place.
