After combining the needs of contemporary consumers, the designer decided to combine young art and architectural language to create a new sales office with commercial, interesting and experience. The project is divided into upper, middle and lower floors. Different from the conventional sales office design, the designer displays the space function in the sales office in the form of an independent "box", which enriches the architectural level and ensures the independence of each spatial function. At the beginning, the black metal background wall enters the line of sight, and the transparent glass wrapped by the metal frame is like a "box" suspended in the space. At this moment, the maturity of the designer's use of body block interposition technique has appeared. Yunfan commercial street, as one of the highlights of this project, uses hanging glass to create four-dimensional holographic projection, creates a rich sense of spatial hierarchy with immersive sensory experience, so that the space maintains a high-quality attitude, enhances the sense of space science and technology experience and the sense of trust between people. The crisscross space and the "static" situation derive a strong contrast of "dynamic" 。 When entering the sales office, the whole space is hollow and high. The designer uses the building's block feeling to interpose in the space to create the sequence of space balance; The elegant life experience hall on the second floor is interspersed in the space in the form of "space box". The designer uses the green representing life and vitality as the theme color of life experience hall. The green decoration everywhere makes the space full of young language. If the space is independent, it will be monotonous. The designer can fully demonstrate the ability of space construction and let each space penetrate each other. The commercial street and art museum is located on the third floor of the project, which is presented at the passage of the visiting model room. As another highlight of the project, it is displayed in front of people with fashionable and interesting colors. Space texture and aesthetic feeling, combined with the commercial atmosphere, "go to the sales office" has gradually become the goal of the design.
