I've just added the Southern Gardens neighborhood to the 1956 Parade of Homes section of my website, Wedgwood Tulsa. There were 6 Southern Gardens model homes in the parade, all of the houses are ranch style. The images on the website are from the plan book, which Parade of Homes viewers could purchase for $1.
The house in the drawing above is called "The Haven." This modernistic house boasts pink terrazzo floors throughout the house, stained mahogany paneling, and exposed cedar beams in the ceiling. The kitchen had (has?) hardwood cabinets with peg board doors and Formica countertops.
