A stair hall, looking up

Curved white balconies winding through a tall interior, and why a continuous edge guides movement.

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.
