This project is to create a light condenser for the summer space and winter space inside. The summer space should not be exposed to direct sunlight while maintaining a minimum DA 500 Lux. The winter space should catch as much light as possible in the winter and provide shading and ventilation in the summer.

The diffuse-lighted summer space and the direct-lighted winter space are intertwined in both vertical and horizontal directions. Continuous circulation is created, connecting the summer space and winter space from different levels.
