Classic Marble and Iron Staircase Set

A collection of three classic staircases for SketchUp, featuring marble treads, ornate iron railings, and wooden details. This set contains three distinct staircase designs suitable for grand architectural interiors. The first is a straight flight with a solid dark wood side panel and marble steps. The second is a symmetrical bifurcated staircase featuring a central flight that splits into two landings, complemented by intricate black iron balustrades. The third is a modern spiral staircase with a white curved stringer and marble treads. Each model incorporates detailed balusters and handrails, providing a cohesive aesthetic that balances traditional material richness with structural elegance. The proportions are designed for large-scale foyer or atrium applications.

The download is a 44 MB compressed archive containing the native SketchUp (.skp) model holding 3 separate objects. It opens directly in SketchUp; for 3ds Max, Blender or Cinema 4D, import it through a SketchUp importer or convert it first.

When working in SketchUp, load these components as individual family blocks to maintain scene performance. Use the component browser to swap or rotate the stair models to suit specific floor plan requirements. Ensure that the material textures are correctly mapped within the native editor, as the marble and wood finishes may require minor UV adjustments if scaled significantly. These models are structured with clear layer separation for the balustrades and treads, allowing for easier material overrides or customisation during the design development phase.
