The renewal of mountainous campuses in the stock market and the reshaping of old school values in urban renewal. With the transformation of urban construction from incremental to inventory, and the evolution of urban management from extensive to refined, topics such as "urban organic renewal", "existing building renovation", "land composite use", and "correction of anti natural construction" have become hot topics for discussion.Resolving height differences is both a core challenge and a solution approach. The solution to the problem is to adapt to local conditions, integrating the resolution of altitude differences and the protection of ecology, and transforming unfavorable terrain into a campus spatial feature that integrates natural mountain terrain. The design focus is on the integration of new and old buildings, the integration of teaching buildings and mountainous environments, and the construction of a new narrative experience for campus space. The design strategy is to increase the main body of the building while retaining and renovating the original exterior facade, and erect the main body on the mountain according to the terrain. Re plan the outdoor space, adjust the experience line, and connect it with the entire spatial path, forming the largest natural spatial feature of Yuxi Ecological Experimental Primary School.The biggest environmental feature of this campus is that it is half mountain and half school, and the natural ecological scenery of the mountains and forests is the most infectious. In the initial design goal, it was to integrate the building into the environment. The designer scattered the building to form several individual buildings, and placed them at different heights on the mountain, hidden in the green ecological mountain. Over the years, buildings will form a symbiotic relationship with the mountains: hiding in a forest of rocks and appearing faintly in the green of the rocks.
