Contemporary Mixed Material Spiral and Helical Stair Collection

This comprehensive SketchUp collection features 28 distinct spiral and helical stair designs in various metal and wood finishes. This library contains a diverse array of vertical circulation assets, primarily focusing on spiral and helical stair configurations. The collection includes various structural systems, ranging from central column spiral stairs to curved helical flights with open or closed risers. Materials represented include timber treads, steel stringers, and mixed-metal balustrades with vertical pickets or horizontal rails. Several models feature complex geometry, including double-curved stairs and integrated landing platforms. The variety in design provides options for both compact residential circulation and larger architectural features, with varying levels of detail in the handrails and tread finishes.

The download is a 21.7 MB compressed archive containing the native SketchUp (.skp) model holding 28 separate objects. It opens directly in SketchUp; for 3ds Max, Blender or Cinema 4D, import it through a SketchUp importer or convert it first.

To integrate these stairs into a SketchUp project, import the desired file and use the scale tool to adjust the overall dimensions to match your floor-to-floor height. Since these models are provided as individual components, ensure you verify the orientation and axis alignment before placing them. Use layers or tags to manage the visibility of balustrades versus structural components, allowing for easier editing of materials or the addition of custom textures to the treads and stringers.
