2 story retail stores

This is a big issue in center cities, where land costs make sprawling one story retail behemoths pretty rare. But because chains predominate all the retail sectors this makes it hard to attract certain kinds of retail to cities. The Raleigh News & Observer reports that some chains are starting to accept more two story configurations.

WHY BUILD UP?

Pros
* You'll need less land, which is becoming more expensive.
* Your store can fit into a more compact space.
* You can build in areas that normally are off limits, such as downtowns and busy city corners.
Cons
* A higher building requires more material, and prices of concrete and steel are on the rise.
* Installing elevators and escalators can be pricey.
* With more floor area, you need more staff.
* You'll need a different store design for a two-story building.
