What type of plan would typically show the layout of rooms and walls in a building?

A floor plan is designed to provide a detailed layout of a building's interior space, illustrating the arrangement of rooms, walls, doors, and other structural elements. This plan is typically drawn to scale and presents a bird's-eye view of the layout, allowing for an understanding of how spaces will interact and flow within the building. It serves as an essential tool for contractors, architects, and builders when working on the construction or renovation of a structure.

In contrast, a section plan depicts a cut-through view of the building, showing vertical planes that highlight the interior volumes and relationships between various levels. An elevation plan presents the exterior view or facade of the building, displaying how it will look from the outside. A detail plan focuses on specific components or features, providing in-depth information about construction details without offering an overall layout of the spaces within the building. The floor plan is essential for visualizing and organizing interior space before actual construction begins.
