"Drone view of an eco-friendly settlement consisting of 20 private houses evenly distributed across rolling hills and natural vegetation. Each house features a south-oriented single-pitch roof with solar panels and vacuum tube collectors (40 tubes per house, 10 solar panels per house) prominently displayed. The settlement integrates stone pathways, a central landscaped park, bioponds, and native vegetation. Wide panoramic perspective captures all 20 houses, infrastructure, and the harmonious integration with the natural terrain. High-definition photorealistic rendering in 8K, ray-traced lighting, realistic textures, and ambient occlusion emphasize the eco-architecture and sustainable design under soft golden-hour lighting."
