As with pavement, there are a number of considerations to keep in mind when select­ing materials and designing patterns for landscape structures.

Relation to House

Every attempt should be made to visually connect site structures to the house so that the landscape and house appear as one unified design statement (Figure 12—72). This can be accomplished by repeating materials such as stone, brick, or paint color on the fapade of the house in nearby walls, fences, arbors, and so on. In addition, the de­signer might carefully select certain architectural details of the house and replicate them in nearby site structures (Figure 12—73).

Character and Function

As discussed at the beginning of this chapter, materials should be selected for their ap­propriateness to the region and neighborhood in terms of visual character, climate, and availability of materials. It is necessary to look beyond the particular residential site to determine what is suitable or not suitable for the setting. In addition, the character of structures should fit the style of other landscape features. It is often helpful to study al­ternatives to determine which is most fitting for the overall design (Figure 12—74).

Fence Caps and Frames

Free-standing walls and fences are often more appealing when they have interesting details that give relief from an otherwise flat surface. One technique is to emphasize

the top of the wall and fence with a linear cap (Figure 12—75). Such a cap visually ter­minates the wall and fence surface and reduces the chances of the eye wandering off into the background or sky. The cap along with posts and bottom railings can help to frame the surface much like the frame around a picture.
