Contemporary Grey Marble Straight Staircase with Glass Balustrade

This contemporary straight staircase SketchUp model features grey marble treads and a frameless glass balustrade for interiors. Designed for a high-end interior, this straight-flight staircase features solid marble treads with distinctive grey veining. The structure is paired with a minimalist, frameless glass balustrade that provides an unobstructed view of the surrounding space. The steps are finished with a clean, white marble riser detail, creating a sophisticated contrast against the darker, heavily textured stone treads. The assembly is integrated into a modern architectural setting, complete with vertical recessed lighting and timber-panelled wall finishes, emphasizing the clean geometry and premium material palette characteristic of luxury residential or boutique hospitality design.

The download is a 19.3 MB compressed archive containing the native SketchUp (.skp) model. 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, import this model as a component to ensure easy placement and scaling within your project file. The geometry is organised into logical groups, allowing for precise material overrides or adjustments to the glass transparency and stone textures. Use standard SketchUp layers to manage visibility of the balustrade versus the stair structure. For high-quality visualisations, apply refined PBR materials to the marble surfaces and adjust the glass opacity settings to match your specific environmental lighting conditions and render engine requirements.
