Do you know why there is a big hole in the middle of a large shopping mall?

? First of all, from the perspective of space design, it can meet the most basic image needs and avoid the sense of oppression in a large area of space. Imagine a flat building space with a single floor of 4,000 square meters. Even if the height can be seven or eight meters, what kind of depression will such a large area be?

Then, from the perspective of commercial layout, any business does not want its store to go too deep. There is a simple reason. Businesses that are too close to the street are hard to be directly noticed by people in the past, so they will not attract people who go shopping. Therefore, even if there is no atrium, it is difficult to attract investment in the middle area. Moreover, the larger the visual display area of the store, the higher the value. However, the empty atrium solves the embarrassment of excessive depth, and the circular corridor around the atrium also provides more visible display surface and internal viewing space for business. Not only did it not cause waste, but it also enhanced the value of the store.

Thirdly, judging from the traffic streamline of shoppers, the intersection of people is the most taboo in the streamline organization of a comprehensive shopping mall. An atrium in the middle can meet a large-scale basic circular traffic. Therefore, the shopping crowd will be naturally guided to every merchant on this floor without missing some merchants or getting lost because of the choice of traffic direction.

Fourthly, from the fire protection point of view, the fire evacuation distance of the comprehensive commercial business part is 30m, and the evacuation stairwell is required to be directly outdoors. That is to say, according to the requirements of the national fire protection code, if there is no atrium, once a fire breaks out, people in the middle of the business with excessive depth will inevitably be unable to evacuate.

Of course, the design and planning of business is by no means as simple as an atrium, but through the simple analysis of the above four angles, it should be possible to simply explain why almost all large businesses have to make a "big hole".
