The Bamboo Tea Pavilion is located southwest of the city of Lishu in the province of Zhejiang. Songyang is under the “Protection and Development of Traditional Chinese Villages”, the villages are created from the varying slopes of the mountain. Damushan Tea is an important tourist attraction in Songyang. The ancient tea garden is surrounded by mountains and planting of the tea trees form elegant lines within the mist of the mountains, creating a lightweight and poetic beauty. The main concept of the pavilion is developed from the “lightness” of the environment.
Traditionally, the tea field has little to no space for comfortable resting and play. During the tea picking season, many out-of-province tea farmers gather and parents bring their children into the field. Therefore, the pavilion is built not only for tourists, but also for the local farmers and their family to rest and play while working in the fields.
Bamboo becomes a natural choice of building material as it can be found locally. The pavilion consists of two different sized square platforms ( 6.6m and 5.1m in length), which can provide convenient spaces for different activities. The arrangement of the pavilion follows the natural form of the surrounding landscape and fits in seamlessly with the field around. The three forms of the sloping roofs, angled at 30°, 45° and 60°, are influenced by the natural surrounding scenery of the tea fields, distant mountains and emerging villages between the tea fields.
The Bamboo Tea Pavilion uses Moso Bamboo, varying from 80mm to 120mm in diameter, for structural purposes in the roof system and structural wall system. The bamboo beams form a structural triangle system at the four corners of each square units that become a larger system that is stable enough for the roof across each 5.1m and 6.6m platform. As the top of the roof, the four sloping roof panels comes together to form a skylight. The wall system consists of vertical bamboo columns. The arrangement of the bamboo columns are predetermined due the structural stress and tension from the pavilion itself; they are arranged from dense to sparse starting from each of the four corners to the middle. The pattern is cohesive with roof system, elongating the vertical lines for the pavilion. The slits between each column allows light to penetrate through as well as keeping the weightlessness and beauty of the overall pavilion.
The roof grid system uses 40mm to 50mm diameter of Lei Bamboo which differentiates itself from the structural Moso Bamboo. The Lei Bamboo creates horizontal lines parallel to the tea fields and mountains in the yonder while the vertical wall façades contrast the pattern.
At the top of the first bamboo column, there is a need for a drainage hole. When the wind blows through each piece of bamboo, it produces a different sound as the rotation angle of each bamboo design is different.
The gap between the field and platform is filled with local pebbles and small local plants. As only local materials are used, people can fully emerge into the unique interaction between themselves and nature of Songyang County while staying at the Bamboo Tea Pavilion.
