Closed vs. Open Riser Stairs – Which Design is Best

Staircase design is a crucial element in architectural planning, offering not only functional benefits but also impacting the aesthetics of a space. When choosing a staircase style, one of the primary considerations is whether to use closed riser or open riser stairs. Both designs have unique characteristics and benefits, making each suited to different applications depending on the project’s goals and requirements. For architects, builders, developers, and designers, understanding these distinctions helps in selecting the right staircase style to meet both structural and aesthetic needs. In this article, we’ll explore the features, pros, and cons of each, helping you decide which design best suits your projects.

Understanding Stair Risers: What Is a Stair Riser?

A stair riser is the vertical section between each step (or tread) of a staircase. It defines the height of each step and contributes to the overall feel of the staircase. Risers provide stability and structural support, whether they are part of a closed riser or open riser design. They play a critical role in safety, appearance, and accessibility, factors that are essential for architects and builders to consider when planning a staircase.

Closed Riser Stairs: Structure, Benefits, and Aesthetic Appeal

Closed riser stairs are designed with vertical panels, or risers, between each step, enclosing the space and preventing visibility between treads. This design offers several key benefits:

• Privacy and Safety: By creating a closed space, closed riser stairs are a safer choice for environments that prioritize stability, such as schools, healthcare facilities, and residences with young children or pets. The riser panel serves as a barrier, preventing items from slipping through and helping reduce the risk of trips or falls.
• Traditional and Formal Appearance: A closed staircase often has a traditional look that complements classical and contemporary architectural styles. The closed riser design provides a solid, substantial appearance that lends itself to formal or luxurious spaces.
• Material Options: Closed risers can be constructed from various materials, but precast concrete stair treads are particularly effective for projects requiring durability and design flexibility. Precast concrete is ideal for high-traffic areas, providing a long-lasting, weather-resistant solution that can be customized in color, finish, and texture.

Open Riser Stairs: Structure, Benefits, and Modern Appeal

Open riser stairs are defined by the absence of a vertical riser between each step, creating a visible gap that allows light to pass through. This design has gained popularity for modern spaces due to its unique benefits:

• Open and Airy Feel: By eliminating the riser, open riser stairs offer a sense of lightness and openness, making them ideal for contemporary designs. Open staircases are commonly used in offices, lofts, and luxury residences, where an open, flowing design is desired.
• Visual Impact and Minimalism: Open risers contribute to a minimalist look that enhances the sense of space in small or crowded areas. Stairs with open treads emphasize clean lines, making them popular in spaces where a sleek, modern aesthetic is prioritized.
• Flexible Material Choices: Open riser stairs can be made from wood, steel, or concrete, but precast concrete stair treads are often chosen for their durability and aesthetic versatility. With the right treatment, precast concrete can be used to achieve a high-end look that is low-maintenance and built to last.

Comparing Closed and Open Riser Stairs for Specific Applications

The decision between a closed and open riser staircase will depend on various factors, including functionality, safety, and design preferences. Here’s a comparison to guide the choice for different architectural needs:

• Safety and Privacy: For projects where safety is a top priority, such as residential homes, educational institutions, or public spaces, closed staircases provide added security. The closed riser prevents objects from falling through and offers a more secure footing, which can be a concern with riser stairs featuring open treads.
• Light and Visibility: In modern commercial spaces, open risers may be preferable due to their ability to let natural light flow through. This can enhance the overall atmosphere, creating a more inviting and spacious feel. Open staircases work well in designs focused on creating airy and bright environments.
• Space Perception: Closed riser stairs can make a space feel more solid and compact, which may be beneficial for traditional homes or locations that require a robust look. On the other hand, stairs with open treads can make smaller spaces appear larger, creating a more expansive feel.

Choosing the Right Material: Why Precast Concrete Works for Both Designs

Regardless of whether the staircase has an open or closed riser design, choosing the right material is essential. Precast concrete offers significant advantages for both open and closed riser stairs, making it a favored choice among architects and builders. Here’s why:

• Durability: Precast concrete is known for its strength and resilience, capable of withstanding heavy use in commercial, industrial, or residential settings. It is highly resistant to wear and tear, making it suitable for high-traffic areas.
• Customization: With precast concrete, the design possibilities are vast. Stair treads can be customized in terms of color, texture, and finish to match the aesthetic needs of any project. For instance, precast closed stair stringers can be given a polished or textured finish to complement the architectural style of the building.
• Ease of Installation: Precast concrete stair components, including precast concrete risers and treads, are manufactured off-site and brought to the project ready to install, reducing construction time and potential site complications.
• Low Maintenance: Concrete’s durability also makes it a low-maintenance option, especially when treated with a weather-resistant seal. This quality is beneficial for both closed staircases and open riser designs, offering a practical solution for developers and builders.

Conclusion: Making the Choice for Your Next Project

Both closed and open riser stairs provide unique benefits, and the best choice depends on the specific needs of the project. A closed staircase offers privacy, safety, and a traditional appearance that works well in formal or high-traffic settings. In contrast, open staircases bring a contemporary look and maximize natural light, making them ideal for modern or minimalist spaces.
