# Wooden staircase concept prompts

Generated with the built-in image-generation tool. The approved V3 ground-floor plan was used as a spatial reference.

## Shared prompt

Create an isolated three-level wooden stair system within an approximately 3.0 × 3.3 m central core. Connect basement, ground floor and first floor in one vertically stacked shaft. Use approximately 1,000 mm clear width, 168–173 mm rise, 290 mm going, full landings, 30° pitch, closed risers, 2,100 mm target headroom, continuous graspable timber handrails, closely spaced vertical balusters and completely guarded openings. Show a clean three-quarter cutaway axonometric model in warm natural oak on an off-white studio background. No furnished hall, décor, rugs, plants, people, labels, winders, spirals or impossible floating structure.

## Variations

1. **Stacked U-return:** two parallel straight flights per storey, rectangular half-landing, narrow central well and conventional closed stringers.
2. **Soft horseshoe return:** parallel straight flights with a broad semicircular full landing; only the outer stringer and rail curve—treads remain straight.
3. **Three-flight open well:** three short straight flights turning around a rectangular light well, connected by full square landings.
4. **Stacked L-return:** two perpendicular straight flights per storey meeting at a generous square quarter landing.
5. **Double dogleg gallery:** paired straight return flights with broad full landings and a slim light well, using sculpted laminated-oak stringers.
