Are Floating Staircases Safe? Debunking Myths and Explaining Compliance

October 29, 2025

Floating staircases have redefined modern home design. Their open, minimalist look transforms stairways from functional features into architectural art pieces. Yet for many homeowners, the same ‘floating’ design that creates such a striking visual effect also raises one big question: how can something that looks unsupported truly be safe? At Dixon Stairs in Melvourne, we understand that safety is always the top priority when bringing contemporary designs to life. Our experience has shown that when engineered correctly and installed to Australian standards, floating staircases are not only safe but often safer than conventional stairs.

Let’s explore what makes these designs both compliant and secure, and why their popularity continues to grow in homes.

What Are Floating Staircases, and Why Are They Popular?

Floating staircases are architectural statements that blend structure, creativity and precision. Unlike traditional stairs with visible supports or stringers, floating stairs use concealed steel structures or central beams that give each tread the illusion of hovering in mid-air. Despite their visual lightness, these staircases are feats of engineering built to support significant weight and frequent use.

Design Concept and Structural Engineering

At the heart of every floating staircase is an invisible framework designed for strength and safety, something most people never see but absolutely rely on. Engineers calculate load paths, balance points and anchoring methods to make sure each tread can bear the full weight of multiple users without flex or shift. A well-designed floating staircase typically includes:

  • Hidden steel stringers bolted securely into supporting walls or floors.
  • Precision-milled treads made from solid timber, steel or reinforced concrete.
  • Custom brackets or cantilever systems that distribute loads evenly.

Why Homeowners Love Floating Stairs

It’s easy to see why more homeowners are drawn to them. The rise in floating staircase popularity isn’t just a design fad; it reflects a growing desire for open, light-filled spaces that feel calm and connected. Homeowners and designers are now favouring layouts that feel lighter, brighter and more connected. Floating staircases help achieve this by:

  • Allowing natural light to flow freely through open spaces.
  • Making compact areas feel larger and less confined.
  • Offering customisable materials and finishes for seamless integration with interiors.
  • Acting as a visual centrepiece that adds modern luxury and sophistication.

How Safety and Compliance Are Achieved with Modern Floating Stairs

Safety is not optional in stair design; it’s a regulatory requirement. Every floating staircase installed in Australia must meet the standards outlined in the National Construction Code (NCC) and AS 1657:2018, ensuring that the structure is safe to use and built to last. Modern manufacturing techniques, combined with digital design tools, have made it easier than ever to achieve compliance without compromising on aesthetic appeal.

How Engineers Ensure Structural Safety

Behind every elegant floating staircase is a complex network of structural calculations, material analyses and precision engineering. What may look effortless is, in reality, the product of meticulous design work and strict adherence to engineering principles. Every element, from the concealed steel frame to the anchor bolts hidden within the wall, is designed to bear weight, resist movement and maintain long-term stability under repeated use. They also evaluate:

  • Wall and floor strength to ensure secure anchoring.
  • Material deflection and vibration levels during foot traffic.
  • Long-term performance against environmental factors like temperature and humidity.

Dispelling Common Myths

Even with their growing presence in high-end homes, floating staircases still raise eyebrows. Many people wonder if they’re as safe as they look. Their minimalist appearance can make people question their strength and stability. Some assume they’re unsafe for families with children, while others think they’re a design trend that prioritises aesthetics over function. These assumptions persist largely because the true engineering behind floating staircases is hidden from view.

Myth 1: “Floating stairs are fragile.”

Fact: Hidden steel or reinforced concrete supports make them incredibly strong. They’re designed to handle heavy, repeated loads safely.

Myth 2: “They’re unsafe for families or elderly users.”

Fact: With features like closed risers, handrails and non-slip finishes, floating stairs can be tailored for any household safely.

Myth 3: “They don’t pass building inspections.”

Fact: Professionally installed floating staircases undergo certification, testing and council approval before they’re signed off.

Australian Standards: Key Requirements for Open-Riser and Glass Designs

Floating staircases with open risers and glass components are among the most visually striking architectural features, but they also come with precise safety and compliance obligations under Australian law. These designs must strictly follow the National Construction Code (NCC) and relevant Australian standards, such as AS 1657:2018 (fixed platforms, walkways, stairways and ladders) and AS 1288:2021 (glass in buildings). These frameworks ensure that every staircase not only looks elegant but also functions safely for daily use.

Open-Riser Stair Requirements

Open-riser designs are popular for their light, airy aesthetic. However, to prevent falls and ensure safety for children, these stairs must meet specific conditions:

  • Maximum gap size: Openings between treads must not allow a 125 mm sphere to pass through (roughly the size of a small child’s head).
  • Consistent tread dimensions: Each riser and going must be uniform to minimise tripping risks.
  • Load-bearing compliance: Each tread must support a minimum load of 2 kN (equivalent to approximately 200 kg) at its centre.
  • Slip resistance: Tread surfaces must achieve appropriate slip ratings (R10–R12) depending on their indoor or outdoor application.

Glass Balustrade and Tread Requirements

Glass is a hallmark of contemporary floating staircase design, often used for balustrades, landings or even full treads. To guarantee structural strength and shatter resistance:

  • Glass type: Only laminated and toughened safety glass is permitted for stairs or balustrades.
  • Thickness: Treads and balustrades typically range from 32 mm to 40 mm, depending on span and load requirements.
  • Edge protection: Exposed glass edges must be polished or capped to prevent injury.
  • Fixing and support: Glass must be fixed using engineered brackets, standoffs or channels designed to accommodate thermal expansion and vibration.
  • Balustrade height: A minimum of 1 metre is required when the potential fall height exceeds one metre.

Certification and Inspection

Before approval, floating staircases with open or glass elements must undergo structural certification from a licensed engineer. Councils and private certifiers often require:

  • Engineering drawings and load calculations demonstrating compliance.
  • Slip-resistance documentation for tread materials.
  • Glazier compliance certificates for glass installations.

Choosing the Right Materials for Safe and Stylish Floating Stairs

Choosing the right material isn’t just about looks; it’s about ensuring your staircase stays safe, durable and easy to maintain for years to come. The right materials allow for creative freedom without compromising on compliance or comfort. As professionals, we guide homeowners and designers through the process of selecting materials that meet structural demands while reflecting their personal style.
