|Constructed in 1959, with a bedroom wing built in 1964, the Roland and Marilyn Wehner House is locally significant and individually eligible under Criterion Cas a master's work that reflects the deep influence of Frank Lloyd Wright at midcentury and Wright's principles of modular, affordable, and organic design. Designed by and for the architect himself, the residence was Roland C. Wehner's first opportunity to plan and execute a Wrightian design after his graduation from architectural school and upon joining the firm of an older, established Iowa City architect. Throughout his 42-year career, Wehner successfully repeated the modular design principles he used in Wehner House in future commissions in the numerous schools, churches, and other buildings in and around eastern Iowa. 1 Wehner House also embodies the distinctive characteristics of a Usonian residence, with its attention to site placement within a natural landscape, use of indigenous building materials, and limination of conventional spaces seen by Wright as unnecessary or undesirable. Additional Usonian tenets exhibited in Wehner House include a concern for the indwellers' privacy, the ability to bring the house into harmony with nature through the use of exterior patios, decks and walkways, and windows and doors that carefully frame selected exterior views. Also, a spare, geometrically precise, central pinwheel staircase around which Wehner House is organized, and the carefully laid pattern of the Anamosa limestone used throughout the house reflect elements having high artistic value. Wehner House's periods of significance, 1959 and 1964, reflect the two construction periods of the building.
