Lattice and Trellis Structures: Create lattice or trellis structures that imitate the delicate intertwining of casuarina branches. These structures can serve as decorative elements on the exterior walls or as shading devices for windows and outdoor spaces. Perforated Facades: Design facades with patterns of perforations that resemble the dappled light filtering through casuarina branches. These perforations can be strategically placed to control sunlight, ventilation, and views while adding a sense of texture and depth to the exterior. Rustic Materials: Choose building materials that evoke the natural textures of casuarina bark and branches. Rough-hewn wood, textured stone, or materials with a weathered appearance can create a tactile and organic feel in the exterior architecture.
