How do different methods employed by landscape architects impact the design outcome? This paper identifies and defines design methods in landscape architecture that may be classified as part of four internal and external connections and structures categories. Methods are further examined through two design exercises. In the first design exercise, the identified methods are individually applied to the same simple design which is used as a control. The only variable changed is the method used to design. The resulting designs are shown and analyzed. In the second design exercise, three different methods are applied to a complex design. Similar to the first design exercise, all variables are held constant except for the design methods. The resulting design outcomes are shown and analyzed. One conclusion from this work recommends landscape architecture designers use at least one method in each of four categories: 1) Modeling Systems, 2) Interrelationship and Dependencies, 3) Incorporation and Adadaption, and 4) Structure Problems in order to explore complex design issues more thoroughly.
