Small Boiler-House Annex, c. 1899

Prompt:
Use case: historical-scene
Asset type: archival gallery artwork for The Age of Smoke
Primary request: A small boiler-house annex attached to a larger works, with restrained ventilation and a chimney only where functionally justified. Architecture is the unmistakable main subject; any people, horses, carts, bicycles, goods or tools are sparse scale references only.
Scene/backdrop: Brick masonry, service door, high window or louvre, coherent roof junction and no giant power-station forms. 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: Oblique service-yard view showing annex and its junction to the parent building. Natural eye-level perspective, moderate depth of field, no fisheye, no heroic low angle, no huge empty foreground.
Lighting/mood: hazy sunshine, summer noon; ordinary believable atmosphere with restrained smoke or haze only where plausible.
Constraints: Britain in 1899; 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.
