What type of form transformation is represented in the provided figure?

In the context of architectural design and form transformation, an additive transformation involves building upon an existing structure or form by adding new components or elements to it. This process enhances the original form and often results in increased complexity, functionality, or visual interest.

When a figure showcases an additive transformation, it typically demonstrates how one or more new shapes, volumes, or materials are integrated into the existing framework, creating a cohesive yet expanded whole. This can be evident in architectural examples where new wings, extensions, or elements are added to a building to meet new demands or to create a more dynamic aesthetic.

Dimensional transformations refer to changes in size or scale without altering the fundamental configuration of an object, while subtractive transformations imply removing or chiseling away parts of the form. The option of "none" suggests there is no transformation present, which does not apply in this case if the transformation clearly depicts an additive process. The correct answer emphasizes how the form has been elaborated upon and enriched through the addition of elements, a key aspect of architectural innovation and design evolution.
