This project locates near the Getu River Scenic Area, which is a world-famous rock-climbing destination with many fantastic limestone cliff and huge karst caves. This project is to reconstruct the original rock-climbing reception center and transform it into a climbing gymnasium for international competition and training. The challenge for design comes from how the architect can make the balance with the scenic surrounding, as well as bring out the best of each other. The main body of the building adopts juxtaposed arch timber structure, which not only meets the requirement of high space for rock-climbing, but a metaphor and representation of the Getu karst caves landscape nearby. The slope of roof echoes the ascend and descend of the mountain behind it, and also make the Kannon Cliff visible from the gymnasium stands. People can look over the magnificent limestone cliff when watching the exciting rock-climbing competition on the artificial climbing walls. A series of steel and wood structure roofs of different heights adopt the local rainy climate, and direct people to the main building-------the rock-climbing gymnasium, where people has the fullest experience. From outdoor to the gymnasium, the Kannon Cliff will reappear in the “cave” made of wooden arches. The wooden arch spans 30m and 40m, and the arch height changes gradually with the space height. In order to facilitate transportation, each wooden arch was divided into 4 sections. After being processed in the factory, the wooden components were transported to the site for pre-assemble, and then lifted and assembled by crane. The pre-fabricated timber structure makes the quality of architectures in the deep valleys easy to control and shortens the construction period. Nowadays, various rock-climbing competitions have been held here every year. As an open and attractive place, the gymnasium has also been a popular gathering place for people.
