中庭通常设置中观光梯。

在大中庭处由于视线好、人流大，所以商业价值高，一般沿大中庭周围商铺设计加大进深，以利于布置大商铺，提高租金。
The commercial value of the atrium is high because of its good sight and large flow of people. Generally, the design of shops around the atrium is deepened to facilitate the layout of large shops and increase the rent.
因受观光梯遮挡，其背后商业价值较低，通向卫生间的通道可以设置在观光梯后面。
