Final answer:
Folk housing is the type of housing distinguished by its form of ownership rather than style of architecture.
Step-by-step explanation:
The type of housing that is distinguished by its form of ownership rather than the style of architecture is folk housing. Folk housing refers to houses designed and built by people with no formal architectural training, and their design is the product of generations of trial and error to suit local conditions and resources. Unlike houses designed by architects, folk houses reflect local environmental concerns and resource availability rather than national or international taste preferences.
