YEPSUN QUALITY Cultural and Creative Store is located in the Pingshan cultural community in Shenzhen, Pingshan Art Museum. The indoor area is about 400 square meters, with a floor height of 5 meters. This store displays and sells a full range of products from the local brand YEPSUN QUALITY, as well as books, coffee and tea, and can contain cultural and social activities. The interior design of this store was completed by ARCity Office,starting in April 2019 and opening in November 2019. The original interior space of the store is a standardized concrete grid space, which is extremely mediocre and monotonous, and needs to be designed to create a unique sense to match cultural characteristics of YEPSUN QUALITY cultural brand. Designers tried to insert a complete "spatial plug-in system" to the standardized space to create heterogeneity. This spatial plug-in system is a specific spatial configuration that can be self-contained and self-growing and is highly self-consistently logical . At the same time, this system can be also highly adaptable to a wide variety of spatial boundary conditions and functional needs through appropriate structural and morphological changes. This design was based on the research of typical elements of traditional Chinese wooden frame system and the investigation of the local construction culture of Pingshan. The aim of this project is to form a new spatial configuration that is traditional and also different from the traditional. This spatial configuration consists three concepts: abstraction of structural system, tectonic system and material system. After being abstracted, this spatial configuration is inserted into the original concrete grid. These two systems represent a juxtaposition of two spatial logics, which produces interesting and complex spatial variations and creates large depth of field and different layers of spaces. The design adopts a concept called "constructional abstraction + constructional fusion"to transform and insert traditional Chinese wooden frame system into the standardized and industrialized modern building structure and form a unique dual aesthetic system. The abstraction of structural system This method transforms traditional wooden building structure into a wooden grid defined by the "opening", "depth" and "lifting frame", which is fully visual and can be experienced. This wooden grid is not decorative, and has clear structural properties. By inserting the wooden grid into the concrete frame, two systems of different densities, shapes and materials coexist in a single space and create an aesthetic sense based on constructional differentiation. The abstraction of tectonic system Designers abstracts some typical elements of traditional Hakka buildings in Pingshan (such as tenon and tenon mortise, through-beams, rammed earth walls, large green brick floors, etc.). Distributed in the space, they are both abstract and figurative, rational and sensual, and enhance the unique atmosphere of the space. The abstraction of material system Traditional wooden structure is easy to weather and decay, so traces of time will be strongly revealed on materials. In order to enhance this sense of time passing,designers collected some old woods of different years in Ping Shan from building ruins. By cutting and reusing these old woods, time can be perceived in this space. The fusion of two constructional systems creates a juxtaposition of two spatial scales. The span of the concrete frame is 6 meters which is beyond the normal human body scale, while the span of wooden frame is 3 meters which could make the space more friendly and pleasant.In addition, the fusion of these two systems also create different internal spatial relationships with the simplest spatial logic. The abstract wooden frame makes the place and spatial boundaries blurred and creates many unexpected effects of perception, light and shadow.
