Change the Levels
Elevation changes also mark movement from one area to another. At the driveway arbor, massive stone steps lead visitors down a steep incline from the public area and into a more intimate garden space.
Change in elevation can effect the pace of a garden, says Hursthouse. A gradual shift is more inviting than a quick change in levels. “For instance, a wide, gracious stair beckons you,” he says.
A sunken area or room can help define a space or emphasize its importance; this is particularly useful when making function or style changes in a garden. For instance, an effective design element is to have a seating area that is just a little bit lower than the rest of the garden.
