This house is frequently called the Varner House on the internet, based on subsequent owners of the property; but the architect's project index shows the client as Frank R. Ross. A 1966 article describes the rooftop feature of the Frank R. Ross house as a concrete bowl. Not just decoration, the bowl also contains the chimney for a central fireplace inside the house. This home was briefly shown in the 1973 movie Sleeper.
