Post-tensioned Stone Staircases

A post-tensioned stone staircase allows natural stone to be used in a way that feels almost unexpected. The material remains solid, permanent and deeply tactile, yet the finished staircase can appear light, floating and structurally effortless.

At Carvero, our experience with post-tensioned stone staircases goes back more than 13 years. Over that time, we have developed specialist methods for creating free-standing and floating stone staircases using post-tensioning principles adapted specifically for natural stone. This allows individual stone treads and landings to work together as one carefully resolved structural form.

The result is a staircase with remarkable visual clarity. Heavy supporting structures can often be reduced or concealed, allowing the stone itself to become the architecture. Each flight is carefully developed around the geometry of the space, the selected stone, the structural requirements and the desired visual character of the project.

Post-tensioned stone staircases are particularly suited to contemporary homes, entrance halls and architect-led interiors where the staircase is intended to become a central architectural feature. The contrast between the apparent lightness of the form and the quiet strength of natural stone creates a powerful architectural presence.

Carvero works closely with clients, architects, engineers, interior designers and contractors from early concept through to manufacture and installation, creating bespoke post-tensioned stone staircases that are elegant, technically resolved and genuinely distinctive
