GOODO office design centers on "sustainable design", features green construction, recycling, no dust, no paint, renders eco-friendly and more sustainable construction . Preserves the building space as much as possible. Parametric and rational design methods were adopted, such as geometric composition, structural mechanics, and parametric operation, to effectively reduce the dependence on traditional decoration materials and labor and ensure that the processing and construction accuracy was more in line with product design standards. Moreover, the designers participated in the construction and the assembly in order to represent the value of the design in multiple dimensions. For the parametric design in this project, comprehensive factors are considered, such as load-bearing beams, the storey height, and the utilization rate. The suspended structure is the core design idea, based on the functional requirements of the office. With the Q235B iron plate as the main material, all parts are laser cut and finished to a high quality. The iron plate and structural beams form a vertical tension force, which replaces traditionally used support columns. Metal ribs, 120mm high, are arranged horizontally, and the finished surface of the upper floor can bear a live load of 200kg/㎡. The structural design significantly improves the space utilization, adds comfort, and creates a sensation of openness for the user. Such a sense of form is not only the need of structural mechanics, but also a part of the spatial form. CNC standard parts allow the designers to effectively realize the high precision of construction. Space is alive and continuously grows with the passing of time and the interaction between humans and their environment. We highlight the meaning and value behind the design and the new possibilities of future space design. We ponder on the relationship between environmental friendliness and social and humanistic value from a higher dimension, and promote sustainable design and commercial development.
