What does the abbreviation AF refer to in architectural terms?

In architectural terms, the abbreviation AF refers to "Architectural Firm." This term is used to describe a business or entity that provides architectural services, which can include designing buildings and structures, planning urban environments, and offering consultation on various construction projects. Architectural firms play a crucial role in the creation of the built environment, collaborating with clients, contractors, and other professionals to bring designs from conceptual stages to completion.

The other terms—architectural framework, architectural function, and architectural finance—refer to specific concepts within architecture but do not pertain to the abbreviation AF as widely recognized in industry terminology. Each of these concepts has its own significance in discussions about architecture, such as frameworks that guide design processes, functions that define the purpose of spaces, and financial considerations in project development. However, none of these are encapsulated by the widely accepted use of the abbreviation AF.
