Curbed is making us think again with their new contest: name the ugliest building in San Francisco. And in a city famous for its twee charm, there's still an impressive from which to choose: Fox Plaza building, those ugly condos in the Outer Richmond and Outer Sunset, the structure across the street from the 16th Street Bart stations that houses a McDonalds, anything at the intersection of Van Ness and Market... the possibilities are endless. Head over to Curbed to make your aesthetic preferences heard. (For the record, this is the most beautiful/groundbreaking building in San Francisco.)
