A Open plan is
a staircase with openings where there are normaly risers, regulations
state you must not be able to pass a 100mm sphere through the opening,
this is why we have either a Riser downstand or a Bar on the drawings
below. Open Plan Staircases are more expensive than closed staircases
as they take longer to manufacture than closed.
