The question
What happens when a stair hall has no corners?
Seen from below, the balconies of this interior wind upward in one continuous white line. There are no landings to stop at and no visible fixings, so the eye keeps climbing.
Edge as guide
A curved balustrade tells you where to go without a sign. Each turn is already visible from the one before it.

What we kept
Draw circulation as one line first. Break it only where people need to stop.
