Arizona Room

A semi-outdoor recreational room found frequently in homes in Arizona. The room is typically a patio that has been covered and screened-in, creating an outdoor feeling while preventing excessive heat and keeping insects and animals out. The room generally borders the back yard of the house and is often accessed directly from the living room, kitchen or other common room of the home.

Arizonans would sleep in their Arizona Room before the advent of air conditioning during the summer months because the flow of cool air made them more comfortable at night than enclosed bedrooms.
