Airplane-Window Mountain House

Create a vertical 4:5 black-and-white conceptual travel photograph shot straight through one rounded airplane cabin window from a seated eye-level position. Show the full inner window frame and a thin double-pane reflection, with no airline mark, seat label, wing logo, or person. Beyond the glass, reveal a snow-covered mountain ridge slightly below the camera and one solitary, entirely original futuristic house near the summit. Design the house as a low angular stone-and-glass volume with a sheltered roof, believable foundation, and no access, occupancy, sustainability, or engineering claim. Surround the ridge only with snow and layered clouds; keep the building at a plausible distant scale rather than floating beside the aircraft. Use a slightly elevated viewing angle, subdued silver-gray tones, grain, realistic atmospheric compression, and a sharp window edge with softer terrain. Treat the image as a speculative composite, not proof that the location or flight view exists. No open window, leaning passenger, close terrain hazard, airport or airline identity, named mountain, impossible giant house, vegetation, road, extra building, 4K text, color accent, logo, or watermark.
