The primary aspect included in the interior design power plan is switch locations. This is because interior designers have a significant responsibility in determining how the interior space will function, including the arrangement of lighting controls and the accessibility of switches for users. Proper placement of switches is essential for creating an efficient and user-friendly environment, ensuring that they are conveniently located for ease of use and aligned with the overall design of the space.

While dedicated outlets, conduit sizing, and speaker locations are all important considerations in the power plan, they typically fall more under the jurisdiction of the electrical engineer. An interior designer's collaborative role primarily focuses on how the switches contribute to the functionality and aesthetic of the space. This collaboration ensures that both the practical aspects of lighting and the design intentions align seamlessly, allowing for a cohesive and well-thought-out interior environment.
