4323 Overhill, built by Hugh Prather in 1923 has a stunning arched stained glass window framed by two Spanish Colonial carved columns and extended capitals. The largest stained glass window in Highland Park is possible because of the 30-foot ceilings in this section of the home. Dozens of patterns of brightly colored randomly laid mosaic tile are found throughout the house. You will see mosaic tile also on the dome at The Mansion, another Turtle Creek house.
