This week Opposite Office proposed turning the US Capitol into a fortress The provocative architecture studio created the concept, named Capitol Castle, as a comment on how democracy is increasingly under threat. "It's tongue-in-cheek, but the question behind it is relevant: how can we protect our democracy?" Opposite Office founder Benedikt Hartl told Dezeen. "Democracy is not for free. Most of us living in the USA, or in Europe, know of no other form of government than democracy." "We explored a lot of different design territories, but kept coming back to the brand's original iconic logo from 1969 and 1994 when Burger King looked at its best," its designer Lisa Smith, executive creative director at Jones Knowles Ritchie, told Dezeen.
