The project is located in the lush area of Lixia District, Jinan, which has always been a central business district. Among them, the staff canteen will serve as the "business card of staff catering culture" in this area, providing users with dining, negotiation and other functional requirements. The concept of “staff canteen” has gradually evolved from the ancient “corridor meal” and the western “cold food before meal”. The diversity of space often depends on the strength of class, which has the characteristics of the times. The design inspiration of this case comes from the exploration of the space elements of the canteen. With the “grid” design thinking, the design is implanted from the line of sight and streamline. It aims to break the sense of hierarchy and sequence of traditional canteen, and form a relaxed and active space atmosphere with efficient communication. The “blue” of science and technology and the “green” of nature become the main tone of space. Large area color patches of different shades, plastic materials without time mark, powerful cinematic expression and geometric composition exist in a contactable way. Stepping into the canteen, the striking color attracts people's attention. The mirror ceiling echoes with other indoor elements, guiding people's sight points, breaking the class and distance sense of traditional canteen space. No matter where the diners sit in the canteen, they can have a unique vision and sense of experience.Retro has always been popular. Designers continue the impression of the 20th century left to the world with eternal elegance and elegant simplicity. Green, blue, yellow, these classic colors, covered with a layer representing the unknown “gray”, the visual experience is softer. Solid wood, metal mesh, mirror steel and other materials are used for streamlined functional block. Customized seat combination, in line with the ergonomic shape and leather upholstery material, to maximize the comfort of the experience.
