A punk house is a dwelling occupied by individuals that can be identified as members of the punk subculture. Notorious for their poor housekeeping, punk houses provide shelter to touring bands, visiting friends, and anyone needing a place to stay. Many punk houses produce punk zines and provide venues for punk shows. The concept of a punk house is similar to hippie crash pads of the 1960s. Andy Warhol's Factory was also an early example of an alternative music venue of this sort. The Factory, as the home base of The Velvet Underground, is directly linked to the formation of punk rock in New York City.
