Submerged Plaza Commercial Layout

Quick answer：

A submerged plaza commercial layout refers to a commercial space designed within a plaza that is partially or fully below ground level. This layout is often seen in urban areas where space is at a premium, and it allows for efficient use of underutilized ground space. Such layouts typically include shops, restaurants, and entertainment facilities, and are connected to the surface through escalators or ramps. They are designed to provide convenience for shoppers and to enhance the overall functionality of the urban environment.
