Born in California and trained at USC Pasadena as an architect, Haver arrived in Phoenix immediately after his service in World War II and began working with his brother Robert (a builder) and father Harry (a brick mason).

Ralph Haver is responsible for so much of the design of postwar Phoenix that he ranked among the largest firms of the time.

Haver especially worked with prominent housing developers, including Del Webb, Fred Woodward, David Friedman and Dell Trailor.

Homes are typically less than 1400 square feet and significantly less in the postwar era due to federal mandate in conservation of materials.

Blueprints as verification for authenticity of Haver designs are rare, as many buildings were created outside of Phoenix city boundaries at the time.
