Since the start of the 21^st century, interior design is changing rapidly. Among diversified design styles, the project boldly adopts the style of retrofuturism. “Retrofuturism” is imitation of the early futurist design style in contemporary art. The designer combines the retro style with the futurist style containing elements of science and technology, to highlight the concept of diversified design in the framework, structure, space and colors of design. In a major dark green tone, decorated with metallic silver grey and bronze gold, the futurist feel of science and technology is fully embodied. The project boasts not only a sense of territory and privacy in space, but also communication with the larger space. It enables groups and individuals to play their roles and get along well in the larger space, showing the whole and parts in coexistence. By simple contrasts between elements, an image of retrofuturism is presented. The whole office space shows a retro and futurist sense of science and technology in the division of space, the combination of functions, the use of materials, and the integration of the color scheme and lighting. The designe not only meeting the need of office work, but also embodying beauty of space.
