Hill is especially known for his traditional, grand,
Georgian-style homes, many examples of which can be seen in the
Swiss Avenue Historic District in East Dallas. However, he also designed a number of more modern-looking residential and commercial properties described as
"googie" or
"coffee house modern". Many Dallas residences designed by Hill survive, quite a few of which are registered with the Dallas Historic Preservation League. A collection of his personal papers held by the DeGolyer Library at
Southern Methodist University contain correspondence, journals, photographs of his work, and designs to several of his buildings. He retired in the Dallas area, where he died on 29 May 1977 at the age of 95 and is buried at Grove Hill Memorial Park . == References ==
