Located in the Airport New Town of Changsha City, the project takes "protection" as the original intention, and puts forward the spatial strategy of "valley", "hill" and "ridge". The large-scale courtyard space encloses a "valley" for children in the city. The combination of medium-scale ladder-shaped roof and large steps gives students a more cheerful emotional feeling, perceiving and embracing the "hill" of seasons and climate change. Finally, the small-scale corridor allows children to experience the fun of "mountains ridge" while running or playing.
