Architect: J. Mayer H. Architects
Location: Seville, Spain
Year completed: 2011 

J. Mayer H. Architects is a talented firm with the Mies van der Rohe Award, the Holcim Award, and the Audi Urban Future Award under its belt. One of J. Mayer H.'s missteps, however, was the Metropol Parasol in Seville, Spain. While a good design on paper, the execution and final product do little to engage the surrounding historic city. According to ArchDaily, the building has been "criticized by the citizens because of the contrast with the existing constructions."
