Winter Staircase Spiral Skylight Pecs

Cool, pale winter light floods a skylit passageway, striking the polished stone steps of a descending spiral staircase. The north window casts a sharp, directional beam that cuts across the curve, illuminating dust motes in the air while leaving the lower turns in deep shadow. White frost patterns rest on the outer glass of the skylight, against the warm, honey-toned stone of the steps. Metal handrails gleam with small, distinct highlights where the light hits them at a glancing angle. The spiral geometry creates a tight, rhythmic pattern of repeating arches that pulls attention downward into the building's core. A final highlight rests on the edge of the bottom step, marking the end of the visible descent.
