Match the structure to the coverage goal
A pergola preserves sky and airflow while providing filtered, moving shade. Rafter orientation, spacing, height, and sun angle affect performance. A pavilion or roofed structure creates more consistent overhead coverage and better weather protection, but it also adds roofing, drainage, snow, utility, and foundation requirements.
The right answer depends on whether openness, deep shade, rain protection, architecture, or a combination matters most.
