This publication chronicles the students’ findings that shed light on Neutra’s design process, his collaboration with his clients, as well as the unsung role of Thaddeus Longstreth as Neutra’s proxy negotiator throughout the design and construction stages. During its approximately sixty-three-year lifespan, the Hassrick House tells a saga of design, dwelling, neglect, restoration, and reinvention today as a laboratory for learning. In many respects, the history of the Hassrick House tells an important story of the modernist movement in the US, both regionally and nationally.
