There is a gap between the ground of the yard and the road outside the yard, which can be used as a step. Steps are widely used in design. If the site elevation difference is not large, steps can be used as a transition. The careful collocation of steps and plants not only resolves the height difference, but also makes the steps a beautiful scenery.

The height difference in the courtyard design can be divided into: slopes, steep slopes, gentle slopes, cliffs, scarps, depressions and mounds. The so-called height difference processing, the key is to "distinguish" the height difference of different scales, and the processing methods are different.
