Your next destination is a small, private sitting area just outside the master bedroom. Though it’s part of the overall garden, it feels distinct thanks to a few simple techniques. First, a change in paving material signals a transition. You move from formal bluestone pavers to casual brick and then back to bluestone again. Second, the elevation changes as you ascend a trio of steps. Finally, partial screening provided by tree-form ligustrums and a low hedge of Japanese boxwoods offers the illusion of a separate outdoor room. Viewed from the sitting area, the courtyard appears lush, serene, and very private.
