Then you end up with what Venturi called a
Duck:
By contrast, the duck is a building that has morphed into an ornament, where the decoration
is the building. The "architectural systems of space, structure and program are submerged and distorted by an overall symbolic form...building-becoming-sculpture we call the
duck in honor of the duck-shaped drive-in, 'The Long Island Duckling'". The duck no longer feels or looks like it is a building, because the key structural elements are concealed within its overall, ornamental form. The shape of the external appearance of the building has "submerged" and "distorted" its internal structures and function - the form has superseded the function.

Well, actually it
is. Being a Duck is Modernism's only access to ornament. The whole building becomes ornament. Boston has excellent examples in City Hall, the Carpenter Center and the ICA.
