Many of those also enjoy a large, flat lawn from which to enjoy the view. These two things are compatible, normally, only with some intensive engineering of structures to stabilize the hillside.

This very nice older lady was concerned that her property was in danger of sliding downhill – and in fact, that is possible. The nice, flat yard you see in the photo is created by building a retaining structure some way down from the edge of the steep hillside, and filling behind that retaining structure with soil.
