Prompt: ONE photorealistic architectural photograph, landscape 16:9, largest native output. A broad winter exterior of an original, invented single-storey modernist house, not based on any real or famous building. Long low horizontal volume sitting directly on a pale concrete base on the ground, not raised on columns. Flat roof with a thin dark timber fascia, walls of vertical larch boards weathered to silver grey, one long band of windows with dark frames, a deep recessed entrance porch at one end. The house sits in the RIGHT two thirds of the frame in a snowy meadow, a few bare birch trees behind, soft overcast winter light, muted grey, white and warm wood palette. Eye-level view from a distance so the house reads within its setting. No people, vehicles, fences or signs. The left third is quiet snowy ground and pale sky suitable for a future caption. Calm composition, natural textures, coherent perspective and lighting. No text, lettering, numbers, logos, labels, signs, watermarks, real brands, faces, people, famous buildings, landmarks or artworks. No glass box on stilts, no steel I-beam columns. No warped or melted geometry, broken repeating patterns or impossible shadows. Full-bleed photograph, no frame or collage.
Modifications: converted to monochrome (greyscale), resized to 1600×900, WebP quality 80, metadata stripped. No compositing or retouching. The detail figure applies a labelled CSS crop of the same image.

Prompt: ONE photorealistic architectural photograph, landscape 16:9, largest native output. An original, invented two-storey modernist house, not based on any real or famous building, set on a gentle wooded slope in late autumn. Two stacked rectangular volumes: a lower one of dark brown brick and an upper one of smooth off-white render that cantilevers slightly over a terrace. Deep-set square windows with thin bronze frames, a straight concrete stair climbing the slope beside the house. Placed in the RIGHT half of the frame. Bare oaks and fallen copper leaves around, soft late-afternoon light, palette of brick brown, off-white, bronze and muted green. Three-quarter view from slightly below. No people, vehicles or signs. The left 40 percent is quiet trees and sky suitable for a future caption. Calm composition, natural textures, coherent perspective and lighting. No text, lettering, numbers, logos, labels, signs, watermarks, real brands, faces, people, famous buildings, landmarks or artworks. No glass box, no house over a waterfall. No warped or melted geometry, broken repeating patterns or impossible shadows. Full-bleed photograph, no frame or collage.
