What represents the "A" side of a building when drawing a floor plan?

In architectural terminology, particularly when creating a floor plan, the "A" side of a building typically refers to the side that faces the street. This designation is important because it often represents the primary façade of the building, which is usually the most visible area and the one that presents the overall aesthetic and design intentions of the structure to the public.

This visibility can influence aspects such as zoning requirements, design guidelines, and even neighborhood context. Additionally, planning documents and even local codes may reference this particular side of the building when discussing setbacks, landscaping, and other site-related considerations. The side facing the street may also be where the main public access (entrance) is located, but the key point for understanding the "A" side designation is its positioning relative to the street and its civic prominence.

In contrast, the other options do not universally define the "A" side in architectural norms. The side opposite the driveway may vary based on the property's orientation and does not have consistent significance. Likewise, while the main entrance and the number of windows can be important features, they do not inherently specify the "A" side according to standard practices in drawing floor plans.
