Here’s an article on 8 design principles for residential gardens, shared by landscape architect, Rob Steiner on Garden Design magazine. I’m especially sharing this article for two sets of people, garden lovers with no knowledge of landscaping but want to get started with creating a beautiful garden for themselves; and garden lovers with no knowledge of gardening but considering a profession in it. Whichever category you’re in, one way to get started with something new is understanding it’s do’s and don’ts. And in the case of landscaping, understanding it’s design principles will point you in the right direction as you begin your gardening journey. Read below as culled from Garden Design magazine.
1. Obey the law of significant enclosure
Yes, this one’s a “law,” not just a rule! It addresses the root meaning of garden, which is “enclosure.” This, to me, is absolutely critical in creating a sense of refuge and of feeling oneself within nature’s embrace. 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. Probably derived from behavioral psychology studies, this rule came to me from a professor in graduate school, and it was one of the best things I learned.

Just yesterday, as I was starting the design of a patio that I wanted to separate from an adjacent play area, it gave me instant guidance for how tall a hedge I would need: the area was 17 feet wide, and so my hedge should be at least 6 feet. Sit near a tree in the park, or a wall, and gradually edge away, and you’ll see how it works. Of course, there are times when the point of a landscape design is a monumental sense of scale or view, but the best gardens, whatever their size, modulate a feeling of enclosure and openness, and this rule will help.
2. Follow the regulating line
My formal architectural education also introduced me to 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. For example, in laying out one backyard, I projected the lines of its building addition into the garden space and then aligned the swimming pool and wooden walkway with those lines. The result is orderly and cohesive, even after being softened with planting. “A regulating line,” wrote the great architect (and theoretician) Le Corbusier, “is an assurance against capriciousness…It confers on the work the quality of rhythm…The choice of a regulating line fixes the fundamental geometry of the work….”

The decking on a different project in Pacific Palisades, CA, creates a regulating line that is parallel to the plane create by the gray wall of the house in the upper right of the image. Another regulating line is created by the edge of the pool running parallel to the glass window on the home. These lines intersect at the base of the tree. Illustration by David Despau.[/column]
Le Corbusier hits on the two aspects (a bit paradoxical, perhaps) that make the regulating line so valuable. First is the idea of underlying order: that the garden, for all its naturalness, or wildness, is founded on strong principles—what’s sometimes known in garden circles as “good bones.” Second, that regulating lines—at least as I employ them—are subjective; it’s the designer who identifies and manipulates them to create the garden. And I’d say that the use of the regulating line, more than any other concept, separates professional from amateur design.
3. Use the golden rectangles to get proportions right
Certain rules help us refine design. One is the Golden Ratio which is a ratio of proportion that’s been observed in everything from the Great Pyramids at Giza to the Greek Parthenon and has been used throughout history as a guide to a pleasing sense of balance and order. 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 architects had to learn math. Numerically, the Golden Rectangle ratio is close to 1: 1.6, a proportion I regularly use to lay out terraces, patios, arbors, and lawns. The raised beds in my vegetable garden are 5 by 8 feet. It’s a rectangular proportion that always looks good—they don’t call it golden for nothing!
