|The Weiser House is locally significant under Criterion C in the area of Architecture for the year 1963, the year of its completion. The house is an excellent example of an architect-designed modern Contemporary residence in Boulder County. Boulder County experienced rapid population growth during the 1950s and 1960s which created a need for new housing, much of it influenced by Modern design trends. The Martha Weiser House is an outstanding example of the Contemporary Style popular during the 1950s through the early 1970s. Key character-defining features include the lowpitched butterfly root, visible root beams, relatively open floor plan, combination of wood and stone, lack of applied ornamentation, attached carport, strong horizontal emphasis, interior courtyard, large and often unusually shaped window expanses, and deep overhanging eaves. In Boulder, the Contemporary housing type is most often seen in custom designed homes, such as the Weiser home. The Martha Weiser House is also significant as a representative work of a master architect, L. Gale Abels (1927 -1995).
