Minimalist Grey Marble Straight Staircase with Integrated Lighting

This minimalist straight staircase for SketchUp features integrated tread lighting and a glass balustrade in a lobby setting. This architectural staircase features a clean, straight-run configuration finished in grey marble. The design incorporates subtle integrated LED lighting beneath each tread, creating a floating effect. A frameless glass balustrade maintains a light, transparent profile, seamlessly connecting the lower level to the landing. The assembly is presented within a high-end interior scene that includes a shallow reflective water feature with decorative stone elements and a suspended metallic art installation. The overall aesthetic is restrained and sophisticated, focusing on material quality and precise, linear geometry within a neutral, monochromatic palette.

The download is a 13.7 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 integrating this model into SketchUp, ensure the staircase components are placed on a dedicated layer or tag to maintain scene organisation. Users should verify that the tread heights and run lengths align with their specific floor-to-floor requirements, as scaling may be necessary. The integrated lighting components are ideal for testing indirect illumination effects, while the stone textures can be mapped to custom render engine materials for high-fidelity output. Grouping the decorative elements separately allows for easy adjustment or removal.
