DeGolyer Estate

Dallas, Dallas County, Texas Listed Ref. 78002914 Building Vacant per nomination

Also known as: Everette DeGolyer House (Rancho Encinal)

Why it's listed

Rancho Encinal is a single-story Spanish Colonial Revival house on 43 wooded acres overlooking White Rock Lake in Dallas. Built from 1938 to 1940 for oil geophysicist and book collector Everette Lee DeGolyer and his wife Nell, it was designed by California architects Denman Scott and Burton Schutt. Stone, stucco and brick walls, wrought iron grilles and a red tile roof give it the look of a southwestern hacienda. Inside, a 35-by-50-foot library once held 15,000 volumes, and the Indian Room displays vigas and a curved fireplace. Landscape architect Arthur Berger laid out formal gardens, a magnolia allee, cutting gardens and orchards, some with ornaments bought from the Hearst estate. DeGolyer is regarded as a father of American geophysics, and the house reflects his wide interests and his fondness for the Southwest. The house and grounds remain largely unaltered, and the city of Dallas acquired the estate after the DeGolyer Foundation passed it to Southern Methodist University.

Significance in brief: The nomination presents the house as one of the most important domestic examples of Spanish Colonial Revival in the Southwest and unique in Texas. It is also tied to Everette Lee DeGolyer, a pioneer of scientific oil exploration, book collector and philanthropist. The largely unaltered gardens, designed by Arthur Berger, form an integral part of the design.

What listing means for this property

National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).

Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.

Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.

General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
