The traditional indoor shopping mall is going the way of the dodo bird unless it has a “tentpole” tenant to draw in shoppers like an Apple Store or Nordstroms. What is replacing them are large outdoor shopping centers with large box stores next to each other.
Developers began moving away from indoor malls long before e-commerce, too. The advantage of a big-box shopping center with detached stores is that the property owner doesn’t have to pay the cost of heating and air conditioning for large corridors that generate very little revenue. Also, an outdoor shopping center will attract fewer mutants and thugs because they don’t want to hang around outside in the heat of cold.
I despise those - or some of them. They are absolute traffic nightmares. You can't just pull in, shop, and leave. You have to fight with a gazillion pedestrians crossing all over the place. Whoever designed these things needs a sound butt whipping.
That’s how many mall started out. Large retailers next to each other. The space between them was covered later. Spans that were large enough were filled with smaller spaces, roads became large hallways.
