Monorail Staircase

Monorail Staircase: Sleek Structure, Floating Elegance

A monorail staircase, also known as a central spine staircase or floating spine staircase, is a captivating architectural element gaining popularity in modern architectural design. This innovative design marries structural strength with contemporary minimalism.

Monostringer staircase features a single, robust beam — often crafted from durable materials like steel, wood, or concrete — that runs underneath the treads and supports the entire flight. The outcome is a sophisticated, floating aesthetic that enhances spatial openness, allowing natural light and expansive views to flow unimpeded. This makes central spine stairs an ideal choice for California open-plan interiors and luxury residential projects.

Benefits of Monorail Staircase:


With no visible stringers or bulky framing, these modern California staircases appear light, streamlined, and exceptionally contemporary. They are a perfect fit for minimalist interior design and add significant architectural value to any property.

Each step is securely affixed directly to the central beam, creating the illusion of floating steps. This effect is often enhanced with open risers, contributing to an airy and spacious feel, which is highly sought after in California home design.

Whether you envision a straight central spine staircase, an L-shaped floating stair, or a U-shaped monostringer, these staircases can be custom-designed and fabricated to perfectly align with your space's flow, architectural vision, and specific California building code requirements.
