There are certain laws and principles that are tried true for architecture. The law of significant enclosure says that we feel enclosed when the vertical edge of a space is at least one-third the length of the horizontal space we’re inhabiting. The concept of the “regulating line.” The idea is that an element of architecture (for example, a doorway, or a building edge, even a window mullion) or a distinctive landscape feature (prominent tree, existing pool, property boundary) can “generate” an imaginary line that helps connect and organize the design. Are these principles and processes understood? Arizona has a unique climate and soil make up that is only duplicated a few places in the world. One of the most important part of this process is to allow for the design and build to be where the landscape is going, not where it is starting. Our soil has a original make up here which limits what we can do with certain types of plants and trees. Laying out planters and walls should be looked at. Thomas D. Church, often credited with creating the California Style and it says simply that twice the height of the riser plus the tread should equal 26 inches. So a 6” riser should be at 14” The practical application that I make of the Golden Ratio involves its sibling, the Golden Rectangle, in which the ratio of the short side to the long side is equal to the ratio of the long side to the sum of both sides (a/b = b/a+b)—you probably didn’t know that landscape designers should have had to learn math and these are things that few actually understand. Numerically, the Golden Rectangle ratio is close to 1: 1.6, a proportion I regularly use to lay out terraces, patios, arbors, and lawns.When these principles are put into place you will have an environment that you will enjoy for years to come.
