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.","narrative":"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.","period_of_significance":"1925","architect_builder":"Ralph Adams Cram","architectural_style":"Spanish Colonial Revival","criteria":[],"status_note":"Left vacant and unattended since December 1973 and badly vandalized, with almost every window and the fine mirrors broken.
