For designers, the optimal approach to safeguarding historical monuments or ancient buildings isn't through mere veneration but by making them accessible, tactile, and functional—integrating them into the fabric of daily life and exploring the potential for new uses and enriched experiences within these historical spaces. We constructed streamlined steel staircases that traverse from the first through the fourth levels, connecting the second-floor spaces and knitting together the buildings' isolated "islands" like a flowing river, thereby unifying the site. The staircases' sinuous forms, reminiscent of a protective dragon, weave through the dense architectural landscape, creating a striking visual contrast. The strategic use of Chinese red not only draws the eye amid the subdued tones of the surrounding structures but also accentuates the theme of "Big Red Crayfish" visually encapsulating the fervor of the taste experience and sparking guests' anticipation of a gastronomic journey. This vibrant, red staircase has evolved into a new landmark and popular photo spot, enhancing business traffic and generating additional commercial value.
