John Frank House, Residential architectural landmark in Oklahoma, United States.

The John Frank House is a single-storey home in Sapulpa, Oklahoma, designed by Bruce Goff in 1955 and built in 1956 for John Frank, founder of Frankoma Pottery. Ceramic tiles glazed and fired by John and Grace Lee Frank run through the interior, and the house was conceived to display the couple's pottery.

Bruce Goff designed the house in 1955 and it was built in 1956 in Sapulpa, Oklahoma, for John Frank, founder of Frankoma Pottery. John and Grace Lee Frank glazed and fired the ceramic tiles set throughout the interior. It was added to the National Register of Historic Places in 2002.

The house was built to display the Franks' pottery: John and Grace Lee Frank glazed and fired the ceramic tiles set throughout the interior. John Frank had founded Frankoma Pottery, and the house served as a showcase for the family's craft.

The house stands in Sapulpa, Oklahoma, and is a private residence, so visits are limited to viewing it from the street; there is no public interior access. Its National Register listing dates from 2002, and the register entry is the reference for the property's documentation.

The building was designed by Bruce Goff, an architect who deliberately rejected convention in his work. His unconventional material choices and geometric patterns were radical for the time and continue to intrigue visitors today.
