Staircase Design with Grand Antique Black Marble Triangle Wall

An 24x24 Grand Antique black marble triangle wall transforms your staircase into a dramatic, high-end focal point. The geometric pattern and bold veining demand a thoughtful approach to flooring, railings, lighting, and surrounding decor. Below are three design styles-Modern Minimalist, Organic Luxe, and Industrial Edge-each tailored to complement this statement feature.

1. Modern Minimalist Staircase (Sleek, Monochromatic, Architectural)

Floating treads in light oak or white marble for contrast

Recessed LED strips along each step for safety and ambiance

Linear pendant lights suspended above the staircase

Wall washers to highlight the marble's veining
