Create a detailed 3D architectural render of a modern residential building based on a section cut. The view should show a split-level interior with large open spaces, an indoor staircase leading to the upper level, and a central courtyard featuring a tree growing inside the house. The courtyard is framed by large windows, allowing natural light to flood the space. A minimalist design is emphasized with clean lines and flat roofs. Outdoor patio areas are visible with seating, and the materials should include concrete, glass, and wood. The setting should be daylight, with soft shadows highlighting the architectural features.
