An original design of a building embodied in any tangible medium of expression, including a building, architectural plans, or drawings, is subject to copyright protection as an architectural work. The work includes the overall form as well as the arrangement and composition of spaces and elements in the design but does not include individual standard features or design elements that are functionally required.
The term building means structures that are habitable by humans and intended to be both permanent and stationary, such as houses and office buildings, and other permanent and stationary structures designed for human occupancy, including but not limited to churches, museums, gazebos, and garden pavilions.
