Sewall, Cleveland Harding, House
Why it's listed
This mansion at 3452 Inwood in Houston's River Oaks neighborhood was designed by architect Ralph Adams Cram in 1924 for Cleveland Harding Sewall, a wholesale grocery businessman, and his wife. The couple moved in during 1925. Set on six acres, the 2½-story house has white stucco walls, a low red-tiled roof, many chimneys, and balconies and terraces with iron and wood balustrades. The entrance portal is elaborately moulded, and inside are Spanish decorative tiles, a grand staircase, beamed ceilings, oak doors and several fountains. A garage building with servants' quarters stands across a courtyard. The nomination calls the house an outstanding example of Spanish Colonial Revival design and Cram's finest residential work. After Mrs. Sewall died in 1973, she left it to Rice University. It then stood vacant and was heavily vandalized. Rice's governors voted to sell the land in three two-acre tracts, and a private individual had inquired about restoring it as a residence.
Significance in brief: The nomination calls the house an outstanding example of Spanish Colonial Revival architecture, popular in the United States from 1915 to 1930. It describes the house as Ralph Adams Cram's most outstanding residential work. The Sewalls chose Cram because he had designed the original Rice University campus buildings.

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.
