Extraordinary Solid Stone Staircase Design That Really Shouldn't Work

A traditional cantilever stone staircase design that isn't fixed into a supporting wall? Free-floating? That was a design challenge we at Carvero happily accepted. Our client was very specific: The ideal staircase was to look both traditional in style yet modern in design, defy the odds of gravity and merely float in the room, despite being made of solid natural stone.

Without any cladding, paint or cement pouring, this solid stone staircase design showing astragal mouldings and a very simple soffit, is statically viable and can be fixed by an expert in a short period of time.

The Secret
The secret is a solution of cleverly used post-tension cables within the steps which allow for shapes and designs of endless possibilities. Using post-tensioned cables is an innovative area in stone staircase design and one that we are extremely excited about.

Innovation
Making solid stone look effortless and as light as possible in appearance is the art we will continue to focus on.

Innovation of new materials used in staircase design and pushing the existing technologies to create even  more stunning results is what makes our hearts sing, just like with this new solid stone staircase solution that really shouldn't have worked at all.
