|The Howard and Marian Bennion House, built in 1940-1941, is locally significant under Criterion C in the areas of Architecture and Landscape Architecture. The period of significance spans the initial design and construction of the house and landscape in 1940-1941. The Bennion House is significant for its association with the architect Georgius Y. Cannon (1892-1970). In preparation for her husband's retirement, Marian Cannon Bennion commissioned her first cousin once-removed, Georgius Y. Cannon, to design a house in Salt Lake City. Like his cousin, Georgius Y. Cannon was born and raised in Salt Lake City, but was living and practicing in southern California when he designed the Bennions' home. The Bennion House is significant because it represents the architect's body of residential work for Utah clients designed in absentia. Cannon was influenced by the emerging popularity of Ranch-style domestic architecture in southern California. For his affluent residential clients in Salt Lake City, he elaborated on the aesthetics of the Ranch style to create high-end homes with classical details. The Bennion House is one of the best examples of his residential work, incorporating the Colonial Revival style with a spacious floor plan and full integration with the site, and is one of the earliest known Ranch-influenced houses in the city. The property is also significant in the area of Landscape Architecture as the earliest documented professional work of noted landscape architect Barbara V. Hoag Fealy (1903-2000). Barbara Fealy was born in Salt Lake City, educated at the University of Illinois, and returned to Salt Lake to begin her practice in the 1930s. The Bennion House is her only known residential work in Utah, although she had numerous clients in the late 1930s and early 1940s. In 1945, she moved to the West Coast, and by the 1970s was one of the most prolific and sought-after landscape architects in the Pacific Northwest. Barbara Fealy was known as the matriarch of landscape architecture in the Northwest. Despite some minor alterations over time, the Howard and Marian Bennion House has excellent historic integrity. The house and yard are currently undergoing an extensive rehabilitation. The property contributes to the historic character of its Salt Lake City neighborhood.
