What aspect does the cased doorway symbol in a floor plan signify?

• A. An open door
• B. An architectural feature without a door
• C. Accessibility
• D. A closed door

Answer: (B)

The cased doorway symbol in a floor plan signifies an architectural feature without a door. This symbol typically represents an entryway or passage that is framed but does not have a door installed. It indicates that there is an opening for movement between spaces, contributing to the overall flow and design of the area.

While options related to open or closed doors represent different conditions of door status, the cased doorway specifically communicates the presence of an un-enclosed passage, making it distinct from situations where doors are included. Accessibility is a broader consideration that might relate to design choices but does not directly apply to the cased doorway symbol itself. Therefore, understanding the symbolic representation of architectural features in a floor plan is essential for accurate interpretation of design intentions.
