In the symbiosis of mountains, water, forests, fields and lakes, linpan is scattered freely, forming the production and life style of "one forest for paddy field, one house for forest". Linpan houses with western Sichuan characteristics grow naturally according to different landforms, hidden among tall trees and low bamboo forests, or surrounded or crossed by canals. We take the contrast between "new" and "old" as the starting point of the renovation design, and keep the form of the original physical wall of the building unchanged to derive the functional layout and form a connection with the surrounding water vein.
