The garage functioned as an openable threshold admitting capital into the home

Evidence

The Robie House was concealed from the neighborhood, hidden behind brick walls, invisible to those walking by on the street. Thus, Erlanger and Ortega Govela explain, “the garage was a new threshold that could be closed off or opened at will, a ritual in which the family and home were no longer connected to the neighborhood outside; rather, the garage and the car opened the home to the modern city.” In doing so, it also opened the home to the flows and movements of capital. — Grant Bollmer, Katherine Guinness, The Influencer Factory, 196
