atrium

A wide, continuous open space at least 5 floor levels high inside a multi-story building.

An atrium is a continuous indoor open space of substantial width and at least 5 floor levels high. Only spaces inside regular multi-story buildings qualify as atriums; large indoor spaces in halls, religious structures, monuments, and other special construction types are not considered atriums.

When multiple buildings open onto the same atrium in a shared podium, the atrium may be assigned to each building. A light court or any courtyard which is open to the sky, or which is not fully enclosed, does not count as an atrium.
