What are some differences or commonalities between Mackintosh's designs and Guimard's? Group of answer choices Guimard favored swirling, often asymmetric ornament while Mackintosh's designs are more geometric and symmetrical. Unlike, Guimard, who embraced cast iron as a building material, Mackintosh's buildings are always traditional masonry construction, never supported by iron frames or concrete. Both Guimard and Mackintosh were rationalists, with their complex ornament directly informed by the structural logic of the object. Neither Guimard nor Mackintosh looked to nature for inspiration. Gumard's designs were praised as being distinctly French, but Mackintosh had little interest in traditional Scottish ornament or folklore
