Located on the west of the main axis of the Flower Expo Garden, the Bamboo and Rattan Pavilion is the smallest pavilion at this flower expo,. On a bird’s-eye view of it, there are no such architectural elements as walls, roof, doors or windows, etc. It seems more like a huge woven bamboo ware than a conventional building of Expo. Similar to the “unconventional design” of the architectural form, a series of original and “unconventional” construction programs are developed by architects, structural engineers and craftsmen through their hard work in material utilization and construction technology, which breaks through the design paradigms of the current horticultural exhibition buildings. Therefore, we call this design practice “unconventional customization”.
