Unlocking the Elegance of Internal Staircases: A Comprehensive Guide (2023)

In the realm of home design, internal staircases stand as indispensable elements, especially in multi-story residences. Beyond mere functionality, these structures can transform spaces, becoming key highlights in home aesthetics. Join us as we delve into the intricacies of internal staircases, exploring placement considerations, width standards, types, and the diverse materials that breathe life into these architectural features.

1. Placement Strategies for Internal Staircases

The location of a residential staircase is intricately tied to the dimensions of the space it occupies. In larger areas with higher ceilings, the L-shaped staircase takes center stage, strategically positioned in the middle or even as a free-standing structure. This design effectively divides spaces like dining and living rooms, with meticulous finishes enhancing its visual appeal. Conversely, compact spaces benefit from transversely placed or corner-situated staircases.

2. Determining the Width of Internal Staircases

Essential to the safety and comfort of staircases is their width, with a minimum requirement of 80 cm. However, this dimension varies based on usage, foot traffic, and local regulations. Tread depth typically ranges from 27 to 30 cm, while the riser height, known as the "mirror," spans between 15.5 and 19 cm. Complying with accessibility standards, changes in staircase direction necessitate landings for smooth transitions, a crucial consideration for staircases exceeding 15 steps or 2.90 m in height.

3. Unveiling the Diversity of Internal Staircase Types

Architects can choose from various internal staircase models, each aligning with specific spatial dynamics.

3.1 Straight Staircase

The most common, the straight staircase, excels in simplicity, making it ideal for smaller homes. Its linear design allows for diverse finishes, encouraging creative construction while ensuring child and elder safety.

3.2 Spiral Staircase

Introducing an artistic touch, the spiral staircase revolves around a central axis, forming an elegant spiral to the next floor. This design optimizes space, acting as a sophisticated sculpture within the home.

3.3 L-Shaped Staircase

Taking a 90-degree turn, the L-shaped staircase suits larger spaces with higher ceilings. Incorporating landings at turning points, it exudes versatility in design, fitting seamlessly into expansive environments.

3.4 U-Shaped Staircase

Resembling the letter 'U' in its floor plan, this model demands more space but offers opportunities for creative utilization beneath the staircase. Gardens, offices, or libraries can find a home under its elegant ascent.

3.5 Floating Staircase

Embodying modernity, the floating staircase boasts a sleek design without handrails, its structure seamlessly embedded in the wall for both safety and sophistication. A perfect fit for contemporary interiors.

4. Materials Crafting Internal Staircase Elegance

4.1 Porcelain Staircase

Renowned for versatility and durability, porcelain offers an extensive range of design options, mimicking wood, marble, or concrete. Its non-slip nature adds an extra layer of safety.

4.2 Marble Staircase

Despite its regal appearance, marble comes with a higher price tag. Its porous nature demands careful consideration for long-term maintenance. White marble remains a classic choice for various decor styles.

4.3 Wooden Staircase

Symbolizing diverse design styles, wood requires meticulous selection for resilience. Treated and certified wood ensures longevity, with alternatives like wood-like porcelain offering sustainability without compromising aesthetic allure.

4.4 Iron Staircase

Suited for industrial-themed interiors, iron complements materials like wood, concrete, or glass. Its cost-effectiveness and adaptability make it a versatile choice in diverse decor scenarios.

4.5 Concrete Staircase

A staple in staircase design, concrete opens doors to numerous stylistic combinations. Pairing exposed concrete or burnt cement finishes with materials like wood or marble creates a visual spectacle.


Internal staircases are not mere functional elements; they are canvases for architectural expression. By understanding placement, dimensions, types, and materials, architects and homeowners alike can embark on a journey to elevate their living spaces. Whether opting for the classic straight staircase or the contemporary floating design, the marriage of aesthetics and functionality defines the essence of a well-crafted internal staircase. Explore the possibilities and turn your home's vertical transition into a captivating design statement.
