Description
Description

Stairs, stairways, staircases, or stairwells, are building components that provide users with a means of vertical movement with the distribution of separate and individual vertical steps. In a building setting, a flight of stairs refers to a complete series of steps that connects between two distinct floors. Either as conscious design decisions or as reactions to existing spatial conditions, stairs can take on a variety of organizational types from straight runs to spiral, L-shaped, U-shaped, or circular forms. Each stair step is typically comprised of a horizontal tread and a vertical riser.

Stairs are designed to establish a route or bridge between vertical levels by dividing the distance or height into steps feasible for occupants to travel. Stairs refers to a stairway, staircase, or stairwell while steps refers to the individual vertical distances that make up the stairs. There are many various types of stairs that can be straight, curved, or a set of straight pieces connected at a turn or landing. There are general requirements for a stair’s minimum and maximum tread depth and riser, with a tread being the component of the stair that the occupant steps on and a riser being the vertical component between each tread. 

History
History

Stairs have been with us since ancient times, allowing people to navigate vertical spaces. From simple stone steps in ancient civilizations to intricate wooden staircases in medieval castles, they evolved to match the era's architectural style. The Industrial Revolution brought metal and cast iron designs, often seen in urban settings. Over time, the purpose of stairs expanded beyond utility to include artistic expression, with designs reflecting cultural tastes and advances in engineering. Today, they're integral to our built environment, showcasing both function and beauty.

Future
Future

As we move forward, stairs are not just about getting from one floor to another; they're becoming pieces of art and interaction. The rise of smart homes brings stairs with LED lighting and sensors, lighting up each step as you walk. In urban homes, floating staircases and glass treads offer a modern aesthetic, maximizing space and light. Eco-friendly materials, like bamboo or recycled metal, are becoming popular, aligning with sustainability goals. Multi-purpose stairs with in-built storage or seating are on the rise, maximizing utility in compact spaces. These evolving designs merge form, function, and innovation, making stairs central to architectural expression.

Common Questions
Common Questions
What are the main parts of a stair?

The main parts of a stair include the treads, which are the horizontal surfaces that you step on, the risers, which are the vertical surfaces between the treads, the stringers, which are the structural support for the treads and risers, and the handrail, which is a safety feature that provides a hand grip for people using the stairs.

How can accidents be avoided on stairs?

To prevent accidents on stairs, keep them clean and clutter-free, well-lit, and equipped with handrails. Wear non-slip shoes and hold the handrail while using the stairs. Be careful when carrying objects and repair any damaged steps.

When were stairs invented?

It is difficult to determine the exact date when stairs were invented, as they were likely developed independently in different parts of the world at different times. However, the oldest known stairs were discovered in the ancient city of Ur in modern-day Iraq, and are believed to date back to the early 4th millennium BCE. These stairs were made of brick and were used to provide access to the city's ziggurat, a large pyramid-shaped temple.

Stair Profile - Open, Mono
Scale illustration of Open Mono Stair Profile compared to other stair profile types

Open stair risers with a mono stringer create a sleek, modern aesthetic. The design lacks vertical risers, promoting an open, airy feel and enhancing light flow. The mono stringer, a single, centrally-located structural element, supports the treads, providing the necessary stability. This minimalistic design, often crafted in metal or wood, transforms the staircase into a sculptural element in the space, embodying contemporary elegance. The mono stringer also allows for design versatility in tread materials and shapes. The combination of open risers and a mono stringer forms a harmonious blend of design and engineering, resulting in a visually striking staircase.

Open Mono Stair Profiles are constructed with typical stair tread thicknesses between 1.5”-4” (3.8-10.2 cm) and allowable nosing overlaps of 1”-1.5” (2.5-3.8 cm).

Stair Widths
Diagram comparing multiple measured widths of stairs with a single person for scale

Stair widths in construction are crucial in ensuring safety, accessibility, and efficient flow of foot traffic. In residential settings, stairs are generally narrower, catering to fewer occupants. Conversely, in commercial or public buildings, wider stairs are necessary to accommodate a larger number of people and to facilitate swift evacuation in emergencies. In venues like theaters or stadiums, where there is high foot traffic, even wider stairs are needed. Additionally, stair width must account for individuals using mobility aids, ensuring their safe and unhindered passage. Local building codes often dictate specific requirements for stair widths.

For stairs serving a single user (typically private residential), a minimum of 36” (91 cm) is required. In general public spaces a minimum of 44” (112 cm) must be met—providing ample space for one person and allowing the tight passage of two people. Comfortable two person stair widths range between 49” (125 cm) to 60” (152 cm). For three simultaneous users, a minimum of 74” (188 cm) is recommended. Handrails must be placed every 60” (152 cm).

Baluster - Ring, Double
Comparison drawing of Double Ring Baluster compared to similar baluster types

A Double Ring Baluster is a stairway support featuring two circular elements within its design, often paired with vertical bars in balustrades. Made from materials like wood or metal, it ensures structural integrity while delivering a unique visual effect. The dual rings provide focal points that break the vertical linearity and enrich the design's dynamic appeal. This style of baluster strikes a balance between minimalist elegance and geometric interest, ideal for those looking to add a touch of sophistication to their interior designs.

Double Ring Balusters have an overall width of 4” (10.2 cm), depth of .5” (1.3 cm), and ring placement at 7” (17.8 cm) from the handrail. Lengths of balusters vary depending on their placement in a balustrade, but are typically sized to match handrail heights of 34”-38” (86.4-96.5 cm).
