futurism exterior shot design a modern alpine house built on a sloped mountain terrain strictly respecting a stepped volumetry with three rectangular levels each offset backwards as shown in the reference massing model level 1 lowest is the largest volume fully embedded into the slope on the back side with large panoramic windows level 2 sits above and behind level 1 recessed backward by the exact depth of the middle terrace level 3 sits above level 2 also recessed backward forming the smallest top platform the three levels must maintain clean horizontal lines architecture style warm modern alpine natural wood cladding dark metal accents stone base large floor to ceiling glazing flat roof terraces on all three volumes top terrace includes an infinity pool with a glass bottom visible from level 2 ensure all terraces follow the exact stepped geometry level 1 large front terrace level 2 medium terrace aligned exactly with the second step level 3 smallest terrace hosting the pool environment mountains lakeside early morning light realistic materials 4k photorealism camera angle should clearly show the stepped structure and the backward offsets between the three levels architecture
