A hilltop midcentury house designed by a respected architect near the University of Oregon in Eugene has been exciting design enthusiasts for decades for its glass-encased sunken living room and treehouse-like pavilions. The residence was designed by award-winning Eugene architect Otto Poticha. Poticha graduated in 1958 from the University of Cincinnati, where he met his future wife, the late Sharon Scott East Poticha. His classmates included future architects Bob Frasca, who designed Portland’s airport, and Michael Graves, the designer of downtown Portland’s controversial postmodern Portland Building. In 1968, the firm, renamed Unthank Seder Poticha Architects, expanded to include notable architects and University of Oregon architecture professors DeNorval Unthank Jr. and Grant Seder.
