World's 10 ugliest buildingsJanuary 2, 2013From Thailand to Toronto and both American Washingtons--these 10 office towers and public buildings, say Reuters photographers, are the ugliest in the world. What do you think?Chang Building, ThailandUgliest Buildings10. Royal National Theatre; London, U.K. Yes, Shakespeare wrote that "All the world's a stage..." but he might not have had he lived to see 1970s. While we love the idea of the theatre and the world-class productions mounted here, our feelings don't quite extend to the actual building.Ugliest Buildings9. The Pixel Buildling; Melbourne, Australia Yes, the building is carbon neutral, but how many Olympic mascot pins had to die to make it? While we love that the building is self-sufficient (they even collect their own rain water on the roof), we just wish it were a tad more subtle.Ugliest Buildings8. Trump Tower; New York City, New York When it was completed in the early 80s it was considered the signature building of its time...and that's part of the problem. Downright dull on the outside, dizzyingly gaudy on the inside, this outdated building is generally only visited by tourists as it is almost universally avoided by actual New Yorkers.Ugliest Buildings7. Epi Apartments; Seattle, Washington We're all for occasional quirkiness, but in this case we're not sure how adding a bunch of almost intimidating, sharp-looking metal shapes onto an otherwise bland building enhances it. The building's website boldly refers to the structure as "The center of the center of the universe."Ugliest Buildings6. Chang Building ("The Elephant Tower"); Bangkok, Thailand It's not that we think the design is that bad and we even like the intended humor. It's the half-hearted execution that turns this potentially fun idea from attraction to eyesore.Ugliest Buildings5. Geisel Library; University of California, San Diego, CA This library is one of the best examples of Brutalist architecture ever built, and that's not a compliment. Named after Audrey and Theodor Geisel (better known as Dr. Seuss), we think it would have been a whole lot prettier had its benefactor also been its architect.Ugliest Buildings4. Aoyama Technical College; Shibuya, Japan Ever wondered what you get when you cross a Transformers figurine, an oil well, and a curling rock? Now you know. The school's site offers that the building "represents a new order...through the tolerance of chaos."Ugliest Buildings3. Sharp Centre for Design; Toronto, Canada Although some call it innovative, there are others who call it intolerable. While the building's black and white squares combined with pencil-like stilt supports make it look like a clubhouse for crossword puzzle enthusiasts, this building is actually part of the Ontario College of Art & Design.Ugliest Buildings2. Rock and Roll Hall of Fame and Museum; Cleveland, Ohio Even the architect was unhappy with this one. Upon the building's completion, a displeased I.M. Pei admitted himself there's little harmony in these conflicting shapes.Ugliest BuildingsJ. Edgar Hoover Building (FBI HQ); Washington, D.C. This is reason alone to avoid the 10 Most Wanted list. Situated in the center of the city, this dreary 1970s behemoth is almost unavoidable. Its days may be numbered as discussions about the department's relocation are rumored to be swirling around the capital city.
