In the examples of landscaping for front door entrances that we've considered so far, the ground between the street and the entryway has been level. In such cases, pursuing the objectives of leading the viewer's eye to the entryway and making the route to the house entrance inviting are not a pressing matters. Rather, they are aesthetic considerations -- however admirable. The bottom line is that visitors to your house will eventually find the front door entrance, regardless of the landscaping.
But it's quite a different matter when visitors must ascend a slope to approach your front door entrance. You have a practical, functional challenge with which to deal first and foremost. You must install landscaping that will provide access from the street to the front door entrance. Not only that, but it must be safe and must not encourage soil erosion on the slope. After functionality has been addressed, then you can consider "curb appeal" (aesthetics).
This challenge is usually met by installing landscaping steps, as in the picture above, although some homeowners might prefer a multi-level deck (with stairs connecting the levels). For curb appeal, brick pillars frame the approach to the stairs, and the pillars are topped with pineapple ornaments. The white metal railings tie in with those on the porch above.
All in all, I'd say the homeowners in this case turned a challenge into an opportunity. What could be viewed as a difficult slope to climb instead has become the canvas for an attractive entryway.
