The Lowell and Emily Parrish House, built in 1951, is locally significant under Criterion C in the area of Architecture. The property was designed by the Salt Lake City-based architect Lowell E. Parrish as his personal home between 1951 and his death in 1960. The period of significance is 1951, the year the house was constructed. Lowell E. Parrish was a prolific architect who designed numerous schools, churches, businesses and residences during his relatively short career. His personal residence at 701 North “I” Street is unique among his oeuvre as a synthesis of the universally popular Ranch style and the eccentricities of the Wrightian Modern style. Parrish designed several brick homes in the Ranch style with open floor plans and access to patios, but in the design of his personal home the architect fully integrated the exterior and interior in his use of materials, planters, and walls of glass. The floor plan is unusual for the period in its lack of right angles. Lowell E. Parrish’s home exemplifies the loftiest and most creative themes of his craft that the architect could not produce in commissions constrained by his public and private clients. It is significant as the only house of its kind in Utah built in the early 1950s. The property is an exceptionally well-preserved example of mid-century domestic architecture and contributes to the historic character of the upper Avenues neighborhood in Salt Lake City.
