Because of the limiting factors of the site, this case constructs a bold idea: to create a natural secret place with light and water in this space isolated from the outdoors. The natural rocks, the Japanese withered landscape, the reflection on the ground, and the symbolic ruins of the site make this garden of dramatic tension point to both the past and the future. And it obtains a seemingly contradictory but extremely rich spatial tension between hybridization and prudence, relaxation and condensation, emptiness and loftiness.
