The grid has no center, no top, no bottom. It is pure relational structure. When Le Corbusier designs the Villa Savoye, the ramp does not proceed from a “front door” to a “throne room.” It spirals through a horizontal slab that is indifferent to facade. The formal basis here is : every point on the plane is theoretically equal. This is not a building; it is a system of coordinates. 2. Transparency as a Formal Operator, Not a Material We mistake glass for transparency. In the modern formal basis, transparency is a spatial and perceptual condition, not a material one. Eisenman, drawing on Colin Rowe’s “Transparency: Literal and Phenomenal,” argues that modern form creates overlapping, interpenetrating volumes that cannot be read as figure-ground.
Consider Mies’s Barcelona Pavilion. The famous onyx wall and the chrome column do not “support” anything in a tectonic sense. They are —vertical surfaces that slide past one another, creating a rhythm of inside-outside ambiguity. The formal basis here is simultaneity of readings . Unlike a Baroque church, where your eye is led to a single vanishing point, the modern plan presents multiple, conflicting spatial layers. You are never fully inside nor outside; you are in the interstice. This is a formal logic of oscillation, not enclosure. 3. The Object as Field: Breaking the Bounded Whole Pre-modern architecture treats the building as a bounded object —a temple on a podium, a cathedral in a plaza. Modern architecture, in its formal basis, dissolves the boundary. The building becomes a field that extends infinitely, even if built only partially. the formal basis of modern architecture pdf
This is most evident in Frank Lloyd Wright’s prairie houses. The chimney is not a center; it is a knot in a woven mat of walls. Roof planes project beyond the foundation, suggesting continuation. Terragni’s Casa del Fascio in Como takes this further: the facades are not four sides of a cube but four autonomous compositions that wrap a crystalline void. The formal basis is non-hierarchical aggregation . No window is more important than another; no corner is a termination. The building breathes by not concluding. The most profound shift in modern formalism is the elevation of the diagram over the representational drawing . A Renaissance drawing shows a building as it will appear to an observer. A modern diagram shows the rules by which the building generates itself. Eisenman’s PDF is obsessed with diagrams of formal transformation: rotation, scaling, shearing, translation. The grid has no center, no top, no bottom
This is a fascinating topic, as it strikes at the very heart of how we distinguish modern architecture from all that came before it. An essay on "The Formal Basis of Modern Architecture" would need to argue that modern architecture is not defined by its materials (glass, steel, concrete) or its social program (housing the masses), but by a radical, conscious shift in its organizing principles of form . The formal basis here is : every point
