The renovation design of Shanghai Baoshan Culture Centre takes functional reorganisation as the core, breaking down the mixed space into three core areas and implanting atriums of different sizes to reconstruct the three-dimensional flow. The triangular roof skylight with decorative aluminium panels gently channels natural light into the curved space, creating a flowing art space. The double-layered skin design is a clever blend of interlocking perforated aluminium panels and transparent glass curtain walls, with seven gradient perforation rates to create a poetry of light and shadow that alternates between day and night, filtering bright light during the day to create a softly lit space, and transforming itself into a lighthouse in the mist at night. The ten-year renovation process has gone through epidemics, business adjustments and residents' demands, and has finally achieved the reshaping of the building's character from heavy to light, and the regeneration of the area's vitality.
