The smooth, organic spline and neutral palette evoke a sense of calm, while the integrated handrail ensures safety without disrupting the clean, unbroken lines.

The plaster surface can be tinted to any matte hue, from soft off-white to warm taupe. The structure is reinforced with a hidden steel frame for stability, and the handrail height meets residential safety standards.

•          Requires skilled plasterers and structural specialists for installation, with a typical timeline of 5–8 days. Starting price at $6,800 (excluding delivery), with custom stone treads and color matching adding 18–25% to the base cost.
