What are the hallways, lobby, basement, elevators, elevator shafts, and storage areas considered in an office building?

The correct answer identifies these areas in an office building as non-productive space. Non-productive space refers to areas that do not directly generate revenue or are not actively used for primary work activities, such as offices or meeting rooms.

In an office context, hallways, lobbies, basements, elevators, elevator shafts, and storage areas are essential for the operation of the building but do not contribute directly to the productive output of the business. Instead, they serve as pathways, access points, or support areas that facilitate movement and functionality within the office environment.

Common areas typically refer to spaces shared by multiple tenants or users, which can sometimes overlap with non-productive space, but they often include amenities that can enhance productivity in a social context. Service areas are associated more with maintenance and operational services rather than usable space by employees.

In contrast, productive space is where employees engage in their work tasks, generating the main income for the business. Thus, understanding the distinction between these different types of space is crucial for assessing the layout and functional design of an office building.
