Staircase

Straight steel stringer. Wood tread. Cable hand rail.

Great seat

A bit boring

Very simple stairway

Doesn't look like it will satisfy the 100mm rule.

Oh yeah !
Railing would need to be simple (glass?) to not hide the great shapes.

Not fond f the B&W, but in other colours would still be very dramatic

Fun

Rod supports.

Nice version of riserless with rod supports. will need horizontal bars in middle of riserless space to satisfy 100mm rule :-(
