The Samuel Merrill house is a fine example of a single-family bungalow - a subtype of residential architecture within the context of the Arts and Crafts period in Pasadena between 1895 and 1918. It is one of the finest surviving examples of the small-scale works of famed Pasadena architects Charles and Henry Greene. It was the home for forty years of Samuel Merrill Jr, a conservationist and friend of John Muir. Built in 1910, at the height of the Arts and Crafts movement in Pasadena, the Merrill House exhibits many of the characteristics associated with the Craftsman bungalow property type. Because of its integrity, its ability to meet the registration requirements as outlined in the Multiple Property Listing "The Residential Architecture of Pasadena, CA, 1895-1918: the Influence of the Arts and Crafts Movement,' and its design by the significant Craftsman architectural firm of Charles and Henry Greene, the Merrill House is eligible for listing on the National Register under Criterion C. - NRHP, 15 August 2000
