Design a modern office courtyard that balances verticality and openness with horizontal flow and structure. Incorporate towering facades with vertical slats for texture, shading, and ventilation. Use light-colored stone or concrete pathways to contrast with organic landscaping featuring vibrant greenery and natural mulch. Maximize natural light with glass elements and an open ceiling while integrating subtle artificial lighting for ambiance. Highlight a neutral gray and metallic color scheme, accented by green from trees and plants and earthy browns from soil. Emphasize biophilic principles, creating harmony between built and organic elements, promoting calm, functionality, and connection to nature.
