Floating Staircases: Single and Double Stringers Explained

Like a sculptor shaping the air itself, floating stairs transcend the constraints of traditional design to offer a peerless aesthetic experience. Have you considered the impact a modern staircase with elegant stairs can have on your home?

Function meets form.

These seemingly levitating stairs are not just feats of design and engineering; they are bold statements that redefine the essence of your living spaces.

Metal Stringers

Traditionally, stringers were made from construction lumber and would be installed in threes: one stringer on each side of the stairway, and one in the center for support. Wide stairways required a few extra stringers for structural support. In these conventional stairways, the stringer was actually built inside the walls, hidden in drywall or paneling, where it became part of the structural membrane of the house.

However, modern homeowners are moving away from traditional staircase design. Single metal stair stringers are beginning to replace the boxy, outdated wood stringers of the past. Instead of being hidden inside the walls, metal stair stringers are crafted to be seen.

Floating staircases are designed to minimize or hide the supporting structure of the staircase. This gives the impression that the stair treads are floating. Floating stairs are popular in open concept spaces. They remove visual obstructions and maximize living space.

The modern and contemporary look is the hallmark of the double stringer staircase. It is a versatile stair that can have nearly any treads and handrail style. Moreover, the additional stringer makes for a super strong structure when compared with a single stringer design, ensuring that the longevity of the staircase will match its timeless design.

Sporting an open, minimalist look, the floating staircases is very appealing for modern homes. You can choose a single mono stringer, double stringer, or even a side stringer to give your home a modern look.

The Anatomy of Floating Staircases

Floating staircases are distinguished by their lack of visible, bulky support structures. The stringers, traditionally the spine of stair construction, are discreetly configured or altogether hidden in these modern designs. Whereas classic stairways rely heavily on conspicuous framework, floating staircases celebrate an airy, almost ethereal presence in space by virtue of their minimalist supports.
The single stringer design denotes a staircase with one central support beam. It’s ingeniously crafted, serving as the pivotal axis for each step, or tread, to cantilever off. This central stringer is usually fabricated from metal or another robust material, its singular form enabling adaptable installation in various environments while also providing a seamless visual continuum that connects each level of the home.
In contrast, double stringer staircases incorporate a pair of parallel support beams. These twin stringers flank the treads, not only providing enhanced structural stability but also contributing to a symmetrical aesthetic. Perfectly poised to support greater loads, the double stringer approach permits designers to couple the functionality with the myriad of material options for treads, ranging from wood to glass, to meet both the practical and stylistic preferences of homeowners.
Engineered for open-plan spaces, the floating staircase’s design minimizes the visual footprint of the structure. Treads appear to float without support, but in reality, are anchored securely either through direct connection to the stringers or by using additional concealed supports. The choice between a single or double stringer often hinges on the balance between the desired visual effect and the necessary load-bearing capacity for the space.
Lastly, the geometry of floating staircases complements the clean lines and open vistas synonymous with contemporary architecture. Whether a silhouette of a single stringer or the harmony of a double, these staircases achieve a balance of functional integrity and visual lightness, designing passages that don’t simply connect spaces, but enhance them.

Customization and Aesthetic Appeal

Design meets personalized function in every installation.

Alternatives to common stairwells are not sparse; however, the customizability of single and double stringer floating staircases is particularly noteworthy. They can be made to conform seamlessly to a space’s unique dimensions and decor, offering not only a functional ascent and descent but also a striking design element. Therefore, they not only serve as access points but also become pivotal in defining the character and aesthetic appeal of a space.
Every staircase becomes a reflection of the homeowner’s taste and flair.
The choice of materials and finishes is vast – from warm wooden treads to sleek metal or glass – allowing for staircase designs that echo the home’s architectural vernacular. This high degree of personalization ensures that each floating staircase not only meets the functional requisites but also resonates with the aesthetic sensibilities of the client.
Meticulously crafted, these staircases embellish contemporary interior landscapes.
The artful blend of form and function distinguishes our floating staircases, which are sculpted to stand as testament to the innovation that defines the ethos of modern architecture. Intrinsically, they represent a synergy of state-of-the-art engineering and artistic vision, tailored to elevate the essence of the home beyond its pragmatic dimensions.

The Single Stringer Advantage

Single stringer staircases possess a structural purity, with a design that emphasizes sleek, uninterrupted lines and a clear path of travel. Their streamlined construction allows for adaptability to diverse architectural spaces, championing a blend of form and function that is distinctly modern. Such staircases offer an aesthetic of fluidity and openness that can transform the most confined areas into expanses of visual continuity.
In the intricate dance between elegance and strength, the single stringer configuration excels as a “floating spine”. It serves not only as the backbone of the staircase but also as a standout design element in its own right. By requiring less material, single stringers reduce visual clutter while maximizing spatial use.

Innovation in Space Maximization

Floating staircases are not just a trend; they represent a significant leap in architectural design, optimizing spatial efficiency.

  1. Elimination of Bulky Support: By removing the need for traditional framing, floating staircases free up floor space.
  2. Transparency in Design: Open risers and the absence of risers allow light to pass through, enhancing the sense of space.
  3. Versatile Placement: The compactness of a single stringer design allows for greater flexibility in staircase location within a floor plan.
  4. Aesthetic Integration: These staircases can be tailored to meld with a variety of interior styles, seamlessly becoming part of the living area.
  5. Structural Innovation: Advances in engineering enable robust support with minimal structural invasion, maintaining an open floor concept.The visual impact of a floating staircase is unmistakable, forging an air of modernity and spaciousness.

By deftly marrying aesthetics with engineering, floating staircases push the boundaries of traditional staircase design to innovate how space is experienced.

The Durability of Double Stringers

Double stringers boast an extensive lifespan, thanks to their reinforced structure and superior load distribution capabilities.
This dual beam configuration not only balances the treads but also significantly reduces lateral motion, ensuring stability and sturdiness. Predominantly crafted from high-grade metals, double stringers withstand environmental variances with resilience, making them a preferred choice for both interior and exterior applications.
In essence, double stringers offer a secure foundation that epitomizes longevity in modern staircase construction. Their reliability is unparalleled, harmonizing both form and function for years to come.
