The soft grid
The grid in architecture is a systematic organization of space. The means that architects use to organize space are, almost by definition, rigid and totalizing. The Cartesian grid, which will serve as the antagonist of the soft grid, is geometrically and topologically unyielding on both the local …

Decomposing the grid
The American landscape chronicles the dreams of an agricultural nation through a series of regular lines en-scribed on a flat plane. Each 6 mile x 6 mile square frames a lose-lose situation in which government subsidies encourage intensive monocultural production resulting in loss of topsoil, …
