The word bungalow, describing a small house of one to one and a half story with a large veranda, came from the Hindi word "Bengali" meaning a house in the style of the Bengal region. The term was first used in an English document in 1696, to describe houses built for English sailors, working for the East India Company in India.
The shotgun style house comes from a house style originating in Africa, with the Yorba Tribe. The long narrow house with, generally 3 rooms in a row, opening into one another, allowed air to pass through the length of the house and cool the rooms. Slaves brought this style to America.
