In Jiande, Hangzhou, Zhejiang Province, a dive club project called "Randall C40+" is emerging as not only a building, but also a kind of urban memory, a regeneration of a calcium carbonate factory, a collision of old and new cultures, and a miracle of waves surging through the mountains.

A fusion of old and new, a reproduction of urban memories, the unique feature of the "Randall C40+" project is that it preserves part of the original calcium carbonate factory's vertical kiln, skillfully integrating the old building with modern design. In the context of urban renewal, one kiln has been preserved, and the ruins of three kilns have witnessed the changes in the city. In the design of the building, we adopted the red brick texture to preserve the old building's appearance, while introducing modern elements to create a trendy façade. The fusion of the old and the new makes "Randall C40+" both historically steeped and modernly energized.
