Quite frequently topographical conditions are encountered that make it necessary to set the house below the grade of the pavement. (Fig. 70.) In such cases the site selected should be just as far back from the property line as practicable, the slope from the house to a point one-fifth to one-third the total distance from the house to the property line to be made rather sharp, with the longer slope from the property line to the established low point. This treatment will seemingly lift the house up and is more pleasing than a grade with the longer slope falling from the house.

Should the point of grade at the house and at the pavement be on the same level (Fig. 71), and provided the house is located well back from the property line, the appearance will be greatly enhanced by making a depression between the house and the street. To do this the elevation of the ground at one side must be below the lowest point of depression. It is very apparent that a lawn graded to such a profile would give a sense of distance while, on the other hand, a convex line would tend to shorten the distance.
