How does the design of an open riser differ from that of a traditional riser?

The design of an open riser is characterized by its ability to allow light to pass through the space between each tread. This is primarily due to the absence of a solid vertical component that traditionally exists in standard risers. The open space not only enhances aesthetic appeal by contributing to a more expansive and airy feel but also can create a unique architectural feature, especially in modern designs. The visibility through the riser allows for natural light to penetrate, which can brighten the staircase area and make it visually more engaging.

Other options do not accurately represent the distinguishing features of an open riser. It is not limited to outdoor staircases; in fact, open risers can be used in various indoor applications as well. Additionally, the height of an open riser does not differ from that of standard risers; they both adhere to similar height regulations to ensure safety and usability. Lastly, handrails are still typically required for safety on staircases with open risers, especially if the design is compliant with building codes, which necessitate handrails for fall protection on stairs.
