Changchun, situated in the heart of Northeast China, was an important industrial city in the early days of the New China Era. In addition, the city is also the origin of China's automobile industry and film industries. This interior design project is a sales center in Changchun Chaoyang Economic Development Zone. As far as the name “Poly City” is concerned, industrial elements and natural aesthetics are this design’s main characteristics and focus. It shows the growth and vitality of a city as well as its evolutionary energy. Taking “life growth” as the design theme, the design team has categorized the life growth of vegetation into four stages: seed sprouting, seedling growth, flowering beauty, and fruitfulness. With this concept in mind, the design team has delicately planned the movement lines of the reception area, hallway, sandbox display area, meeting area, and second-floor space to follow the vegetation’s life growth cycle, reverberating the distinct emphasis of each stage.

The design team breaks the boundaries of conventional design techniques by cutting the angles of oblique and vertical facades in a rectangular body, reconstructing the proportions of space and the “paths” of sight and light. Besides, the interlocking architecture of the blocks and a large amount of environmentally friendly photocatalysts on the façade create the "aerobic atmosphere" essential for life. Also, the magnificent view delivers the unique language of the site, reflecting Changchun's profound industrial development history. At the end of the corridor is a digital wall recording the history of Changchun's development, which symbolizes a connection between the space and time.

The planning of the second-floor space is more about its sharing and inclusivity. The design team has focused on creating a city miniature with the same frequency and pace, where citizens could witness the city’s conversion from a brand new perspective. An extremely long glass drifting platform welcomes the outdoor landscape and injects the vitality and vigor of the sun into the space, shaping the atmosphere of warmth and vividness. On the other side, the design of the meeting negotiation area is titled "Blossom,” where the design team demonstrates a natural and comfortable floral world from a microscopic viewpoint. The area has turned into a place where communication is natural and spontaneous. Other than that, using locally produced metal materials and combining the color and the prototype of the city flower, Cilvia Minata, the design team has delivered the illusionary flower petal art installation suspended from the ceiling and becomes a visual highlight. In addition, mechanical bearings intertwine with greenery, perfectly blending industrial elements with natural aesthetics, representing the power of renewal to bring constant vitality to Changchun.

For this project, the designer has extensively used photocatalytic environmental protection materials and planned the sofa side with a glowing-stone-surfaced display cabinet. From the design approach to the material, the design theme has stayed consistent with the theme and idea of “urban renewal.” To make the interior space attractive, immersive, and architecturally expressive, the design team has resourcefully divided the area with a slanting surface and a wall on the facade, interspersing the horizontal bridge to create multiple visual layers.

With the photocatalytic and earth-friendly material, the space comes with deodorization, antibacterial, and sterilization. Besides, it does not require electricity and frequent maintenance, thus realizing the idea of environmental protection. The primary space of this project is designed with large open windows so that a large amount of natural light is introduced into the room, and the area is bathed in sunlight. With no need to turn on all the electric lights during the daytime, the design plan meets the users' needs for sufficient light sources, reduces energy consumption, extends the service life of electric lights, and realizes the idea of energy saving and carbon reduction.
