This close-up shows how precise a radial layout has to be. A series of tapered treads forms part of a curved flight, and the narrow gray and black veins run across the joints in one continuous sweep.
On a curved stair every tread changes direction, so the cutting plan has to account for piece orientation, inner and outer dimensions, machining tolerances and edge details. That study is especially worthwhile with a pale marble that has strong linear markings.
Curved stairs, turning flights and complete stone stair packages, with slab selection and tread/riser coordination led by the architect. Quotes are based on approved shop drawings or templates.

A full set of curved stair treads laid out in sequence on the factory floor, so the black veins can be checked around the turn before packing.

Tread blanks set out in a long staggered run to see how the big black swirls travel from one step to the next.

Wedge-shaped winder treads set out as a sweeping turn, with the gray-black bands running across every piece.
