Built in the late 1960s, Carefree was the long time-home of Southwestern Studios. The sprawling 47-acre desert property adjacent to North Scottsdale featured state-of-the-art soundstages and production facilities. In the early 1970s, the studio was specifically built by CBS television for The New Dick Van Dyke Show starring Dick Van Dyke and Hope Lange. Later known as Carefree Studios, it was razed in 1999. The Scottsdale Road studio back lot and pristine desert property was developed into retail space and residential development.
