On which part of the floor plans can external finishes typically be found?

External finishes are primarily depicted in elevation plans because these plans provide a visual representation of the buildings' exterior, showing details such as materials, textures, colors, and design elements. This type of plan allows evaluators and stakeholders to understand how the building will appear once constructed, including aspects like siding, roofing, and any ornamentation. Elevation plans are critical for assessing the visual and aesthetic aspects of a project, which is why they specifically include information about external finishes.

In contrast, site plans focus on the overall layout of the property, including landscaping and the relationship of structures to the surrounding environment, but do not provide detailed views of the building's exterior finishes. Foundation plans detail the structural base of the building, indicating how it will be constructed above ground, but do not illustrate external appearance. Utility plans are concerned with the internal functioning of the building, such as plumbing, electricity, and HVAC systems, and do not address external finishes at all.
