Service Details

We're experienced in taking the strain out of the complex engineering needed to produce the finest cantilevered stone staircases.

A cantilevered stone staircase represents the perfect intersection of traditional masonry and modern structural engineering. By utilising the natural compressive strength of stone, we create elegant, gravity-defying flights that offer a level of slenderness and permanence impossible to achieve with other materials.

Our team has designed and installed hundreds of flights, providing a complete service that manages the complex structural requirements of each project. Because the stone provides the finished surface for every face of the stair, these structures offer a streamlined construction process that eliminates the need for additional cladding or decorative finishes.

Material Selection

Choosing the Right Stone

The success of a cantilevered staircase depends on the structural density and wear resistance of the selected stone. We provide expert guidance on material suitability, ensuring the stone possesses the grain structure required to perform under tension.

We prioritize technical characteristics such as bedding planes and mineral variability over pure aesthetics. Our knowledge allows us to recommend materials like Portland or Molianos that meet both the architectural vision and the stringent safety requirements of load-bearing masonry.

By sourcing only high-quality blocks, we ensure every tread is free from structural defects. This careful selection process allows us to achieve the precise, slender geometries required for a safe and permanent cantilevered flight.

Technical Delivery

From Design to Installation

Every staircase is developed through rigorous 3D modeling to resolve complex geometries and ensure seamless integration with the primary structure. Our service includes full structural design and the specification of bespoke bracketry where traditional wall embedding is not possible.

We manage the critical coordination between architects, engineers, and site teams. This proactive approach ensures the supporting substrate is prepared to receive the stone, mitigating risk and ensuring the final installation meets exact tolerances.

Our technical independence allows us to design without material limitation. Whether the project requires traditional tiered treads or contemporary seamless profiles, we provide the insight needed to turn a conceptual sketch into a buildable structural reality.
