In contemporary architecture, the "floating" stair is more than a functional necessity—it’s a sculptural statement. The (or mono-stringer) provides this minimalist look by using a single, robust spine to support cantilevered treads.

Precision Engineering for Modern Aesthetics: Central Stringer Staircase Design

However, achieving this "weightless" aesthetic requires rigorous structural calculations.

Designing a central stringer is significantly different from traditional two-sided support. Because the treads cantilever from a single point, the central beam must resist both and torsional forces .
