What Are the Stairs Inside a House Called? A Deep Dive into Staircase Terminology, Building Codes, and Design Trends

Brief Summary

In residential architecture, the stairs inside a house are generally referred to as interior stairs. While this is the most common term, they can also be simply called stairs or even a staircase, which encompasses the entire structure, including the steps, railings, and any supporting framework. The fundamental purpose of these interior stairs remains the same: to provide safe and efficient vertical circulation between different levels or floors of a dwelling.

Basic Terminology and Components

• Interior Stairs/Stairs: This is the general term for any staircase situated within the confines of a house. It serves to differentiate from exterior stairs, which typically lead to entrances or patios.
• Staircase: This refers to the entire structure, incorporating all its components. It’s a more holistic term, envisioning the stairs as a complete unit.
• Stringers: The backbone of the staircase, stringers are the structural members, usually fashioned from wood or metal, that support the treads and risers, ensuring the staircase’s stability and load-bearing capacity.
• Treads: These are the horizontal surfaces of the steps where you place your feet while ascending or descending the stairs.
• Risers: The vertical components between each tread, risers contribute to the overall rise of the staircase.
• Handrails: Essential for safety and support, handrails run along the staircase, providing a firm grip and stability while navigating the stairs.
• Newel Posts: The sturdy vertical posts that anchor the handrails at key points, such as the top and bottom of the staircase, as well as at any landings.
• Landings: These intermediate platforms break up long flights of stairs, offering a resting point and often facilitating a change of direction in the staircase’s layout.

Building Code Requirements & Safety Considerations

In the United States, interior stairs must conform to stringent building codes to guarantee safety and accessibility for all occupants. These codes govern various design elements of staircases, including:

• Rise and Run: The rise (vertical height) and run (horizontal depth) of each step are meticulously regulated to ensure comfortable and safe strides, minimizing the risk of trips and falls.
• Headroom: Adequate vertical clearance above the stairs is mandated to prevent head injuries, especially on steep or winding staircases.
• Width: The minimum width of the staircase is determined by factors like occupancy and accessibility requirements, ensuring enough space for comfortable movement and emergency egress.
• Handrails: Handrails must be installed at a specific height and extend beyond the top and bottom steps, providing additional support and preventing accidental falls.
• Guardrails: Open sides of stairs and landings necessitate guardrails to avert falls, particularly in homes with young children or elderly residents.

Diverse Staircase Styles and Designs

Beyond the fundamental terminology and code requirements, interior stairs offer a wide array of architectural styles and designs, each with its unique aesthetic appeal and functional considerations:

• Straight Stairs: The quintessential staircase design, featuring a continuous, uninterrupted flight of steps in a single direction. Ideal for straightforward layouts and maximizing space efficiency.
• L-Shaped Stairs: Incorporating a 90-degree bend, often with a landing at the turn, L-shaped stairs add visual interest and can cleverly navigate corners or changes in direction within a house.
• U-Shaped Stairs: Featuring two parallel flights of steps connected by a 180-degree turn and a central landing, U-shaped stairs create a grand and formal entrance, often found in larger homes with spacious foyers.
• Winder Stairs: These space-saving stairs utilize triangular or pie-shaped treads to navigate curved or angled turns without a landing, making them suitable for compact areas or challenging layouts.
• Spiral Stairs: Characterized by a central pole with radiating treads, spiral stairs boast a compact footprint and a visually striking design, often serving as a secondary or space-saving staircase option.
• Curved Stairs: Exhibiting a graceful curve, these elegant stairs add a touch of sophistication and luxury to any home, though they can be more complex and costly to construct.

Remodeling and Renovation Trends: Breathing New Life into Staircases

In the realm of home remodeling and renovation, staircases are increasingly viewed as opportunities to infuse style and personality into a living space. Some prevailing trends include:

• Open Risers: By doing away with the risers, open risers create an airy and spacious feel, allowing light to filter through the staircase and visually expanding the space.
• Floating Stairs: These seemingly gravity-defying stairs appear to “float” without visible stringers, achieving a minimalist and modern aesthetic that complements contemporary interiors.
• Glass Railings: Glass panels or balusters lend a sleek and contemporary look while maintaining visibility and openness, particularly favored in open-plan layouts.
• Mixed Materials: Combining different materials, such as wood and metal or glass and stone, can create a visually captivating and unique staircase that serves as a focal point in the home.
• Statement Lighting: Illuminating the staircase with eye-catching decorative fixtures or integrated LED strips can add drama, ambiance, and enhance safety during nighttime use.

Conclusion

Beyond their functional role, interior stairs have the potential to elevate the overall aesthetic and value of a home. Understanding the diverse terminology, building code requirements, and design possibilities empowers homeowners to make informed choices that harmonize functionality, safety, and style in their staircases. Whether building a new home, embarking on a renovation project, or simply appreciating the architectural details of an existing staircase, an informed perspective can enhance the experience and enjoyment of this essential element of residential design.
