Early modern physics of the 19th century postulated the existence of an aether, or space filling medium which allowed for the transmission of electromagnetic waves and gravitational forces. The aether permeated all space, the substance of nothingness by which immaterial phenomena could be explained through material properties. Architects rely on representational methods to depict space, the absence of matter, in ways that best serve our intentions to manipulate it. This project investigates architecture’s primary pursuit, to create void from solid, through the design of a row house in Philadelphia.
