What is the typical characteristic of a dumbbell layout?

1. Multiple entries on the same side

2. Paths connecting two major spaces

3. Circular movement only

4. Linear movement with no secondary access

The correct answer is: Paths connecting two major spaces

A dumbbell layout is primarily characterized by paths that connect two major spaces, creating a configuration that resembles a dumbbell shape. This design often features two larger areas (the "weights" of the dumbbell) connected by a narrow corridor or pathway that allows for movement between them. This layout is favored in various environments, such as open office designs or certain residential spaces, because it facilitates circulation and provides a clear flow from one area to another. The connection between the two main spaces is essential for maintaining accessibility and encouraging movement, which enhances functionality within the design. While the other options describe different spatial arrangements, they do not capture the defining trait of the dumbbell layout. The presence of multiple entries on the same side might refer to configurations like a linear corridor or an open plan, while circular movements suggest a different design approach entirely. Linear movement with no secondary access could refer to a more traditional hallway setup, which does not align with the concept of connecting two main spaces as seen in a dumbbell layout.
