This project is a sales office project of Ningbo Greentown Phoenix Mansion, which will later be operated as a complex community living pavilion for top luxury residences. It fits the international vision, urban spirit and life aesthetics of Ningbo, and activates the social interaction of the community. By effectively using the inherent column structure, the designer constructs each two columns into a circular arch with built-in light strips, which is together with the ground stone and wall mirrors to shape an infinitely extending “time and space tunnel”. The green spiral staircase connects the first and second floors, catching people’s eye and enriching space experience. The designercreates an immersive atmosphere with light as a modular system and experience between reality and fiction, reality and fantasy by extending the three-dimensional visual sense of the space. As a medium connecting reality and illusion, light perfectly connects the reflected image with real light and shadow. The exchange between the imaginary and the realitycreates an infinitely extending dimension of art, allowing visitors to soar in it.
