For your courtyard, garden room, cloister — the space in between, you have many options. What I’ve done here is illustrate several floor plan ideas. The green represents, well of course your green space, the areas for plants. These shapes will dictate your experience and the gardens functionality. How you walk through it, sit in it or use it for pleasure or production. Some are traditional, tied to a long history of garden geometry while others are more modern or contemporary in style — free flowing, none specific to any clear geometry.
A traditional garden layout can easily become more avant-garde by way of plant choices and a contemporary landscape layout can feel very traditional with a formal plant composition. You can mix and match. Plants are my specialty so once you get a sense of what type of layout you want I can go into depth with flora.
