An Arizona Room is a room that is not quite outside and not quite inside. More than a screened in porch, but neither heated or cooled from the heating and cooling systems of the house itself.
An Arizona room is rather unique to Arizona (thus the name) and it is a blend of indoor and outdoor living space that you don’t see very often outside of Arizona (at least that’s my story and I’m sticking to it.)
Wikipedia has this definition of an Arizona Room
An Arizona room is 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.
Before air conditioning it was a place you could sleep at night and enjoy the cool evening breezes. Even after air conditioning the same is true. If you like the feel of the night air it doesn’t get any better.

This particular Arizona Room is long and narrow with a desk at one end and comfortable seating. Arizona Rooms come in all shapes and sizes. There is no standard or set square footage or shape.
Because we have such warm weather year round there aren’t very many days when you wouldn’t be able to use your Arizona Room. They are not figured into the total living space of a home so when you see an Arizona Room as part of a house it is bonus living space. Something to keep in mind.
