A single-level commercial center design

Quick answer：

A single-level commercial center design typically refers to a shopping complex or retail space that is built on a single floor, without multiple levels or stories. This type of design is often chosen for its simplicity, ease of navigation, and cost-effectiveness. It can include a variety of stores, restaurants, and service facilities, all accessible without the need for elevators or escalators. This design is particularly suitable for areas with high pedestrian traffic and for creating a welcoming atmosphere for shoppers.
