The teahouse is floating in the south of hills on a tea field, Lu Yu Tea Cultural Campus, Huzhou, China. Architects regard the traditional spatial prototype of the teahouse as an inherited design strategy. The teahouse aims to enhance people's experience in the tea field. The approach of 'vanishing' twice in design creates a new and harmonious landscape system. One of the unique elements is the use of 170 steel poles, symbolizing the traditional architectural 'column'. These poles, randomly located in the tea field, create a forest-like setting for the 3x3-meter teahouse, hidden within this landscape installation area of almost 910-square-meters, for which 3-D coordinates are calculated using a parametric design approach. The second disappearance is a natural phenomenon of Cloud. Those steel poles inserted with each spray installation appear and disappear, recycling with the water fog, which gradually gathers, floats, mists, and scatters to fall, disappear, and dew, rendering a scenery for people to walk through the mist. The Cloud Tea Room created a dynamic scene for tea events and inspired a sense of Zen in this historical place.
