Yard Sanitary Block, c. 1888

Prompt:
Use case: historical-scene
Asset type: archival gallery artwork for The Age of Smoke
Primary request: A small detached sanitary service building in an institutional yard, shown only through cautious exterior construction evidence. Architecture is the unmistakable main subject; any people, horses, carts, bicycles, goods or tools are sparse scale references only.
Scene/backdrop: Plain masonry, discreet high ventilation openings, simple doors, drainage and rainwater goods; no interior view. Every opening follows room use and masonry structure; every chimney follows a plausible fireplace and flue route; roof planes terminate with coherent eaves, ridge, valleys where needed, flashing, gutters and downpipes.
Style/medium: Photorealistic historical documentary image, natural worn masonry, timber, glass and roof textures, grounded observational atmosphere, restrained aged photographic tonality.
Composition/framing: Clear three-quarter record view from across the yard. Natural eye-level perspective, moderate depth of field, no fisheye, no heroic low angle, no huge empty foreground.
Lighting/mood: light snow, winter dawn; ordinary believable atmosphere with restrained smoke or haze only where plausible.
Constraints: Britain in 1888; all visible details plausible for 1880–1910, nothing later than 1910. No readable text, captions, labels, borders, frames, or watermark. No modern vehicles, road markings, street furniture, glazing systems, industrial sheds, utilities or materials. No fantasy, steampunk, generic AI-Victorian ornament, extreme HDR, orange/teal grading, exaggerated spectacle or excessive smoke.
