Examples of patterns created by combining different materials. • call attention to the ground plane, especially in areas free of furniture or other objects. • bands; lines or bands of a contrasting pattern extending through the pavement surface (top right, Figure 12-43). One varied pavement material can be employed to:
• create visual interest while maintaining uniformity of material type. Concrete pavers lend themselves to this type of pattern especially well because of their numerous shapes and colors as previously described. • unify a complex paved area that has numerous sides and/or subspaces. Figure 12-43
Alternative ways to treat a pavement area composed of one material. There are numerous ways of creating patterns within one material, including:
• border; the creation of edge pattern that is different from the pattern within (top middle, Figure 12-43). • reduce cost because of comparative ease of installation. This extends the possibilities previously discussed for creating patterns and allows the designer to combine materials in ways that feature the best qualities of each. In studying a pavement’s pattern, the designer should consider (1) the complexity of the pattern, (2) the suitability of the pattern to the shape of the paved area, and (3) the fit of the pattern to its surroundings. The variations in pattern with one material can be subtle or pronounced depending on the degree of contrast that is generated with material differences. The techniques for creating patterns with separate materials are the same as previously outlined for one varied material. • define subspaces or different use areas within the same paved area. • grid; the formation of a grid with lines, bands, or repetitive areas (bottom left, Figure 12-43). This approach is suitable for richly colored and textured materials such as gravel and brick that have inherent visual appeal, but it does not work as well for bland materials such as concrete. One uniform pavement material can be used to:
• provide visual unity when the pavement connects multiple spaces or areas in the landscape. One Uniform Material The first and simplest pavement design is created with one material that has the same pattern throughout the entire paved area (top left Figure 12-43). • express creativity and/or produce an unusual pavement surface. • emphasize material characteristics by combining materials that have divergent texture, color, shape, and so on (Figure 12-45). One Varied Material This pavement pattern is generated with one material that has variation in size, shape, color, and/or direction across the paved surface. • define subspaces or different use areas within the same paved area. caution for integrating different materials is to make sure that they indeed go together both compositionally and technically from an installation standpoint. • create visual directionality and/or linkage with surroundings. • create a ground surface that settles into the landscape and calls little attention to itself.
