Ultra-photorealistic “before → timelapse cleanup → after” renovation sequence in the SAME abandoned indoor stairwell of an old building. Locked tripod camera, vertical 9:16, wide lens, ground-floor viewpoint looking upward toward the stairs and landing. Architecture must stay identical: same stair shape, same window positions, same railing placement, same wall geometry. BEFORE: extreme neglect — peeling plaster, stains, dust, exposed cables near the walls, dirty window frames, damp muddy floor, trash bags, cardboard, scrap debris, tires, and one old broken appliance near the corner. Warm natural daylight streams through the tall windows with soft shadows. TIMELAPSE ACTION: multiple workers in fast motion blur repeatedly carry trash out, sweep, shovel, scrape, and wipe surfaces; debris piles shrink step-by-step; mud clears from the floor; the staircase becomes visible and clean. No morphing—only realistic cleaning/renovation actions. AFTER: the exact same stairwell looks fully restored — smooth freshly painted walls, clean repaired windows, tidy stairs, simple metal railing, bright clean stone/marble floor with subtle glossy reflections, warm sunlight, realistic textures, crisp details. End with a 0.3s match-cut loop back to the original BEFORE frame.
