The Guaranty Building, designed by Louis Sullivan in 1994-1996, is in Buffalo, NY. It was based on Sullivan’s idea that “form follows function”, with each section of the building being dedicated for a different use. The details on this building are also a note-able feature because he thought they could connect a building to the natural world using floral designs. ( Saroja Sethuraman, Re-thinkingthefuture).
