There are a number of places on the residential site where special effort should be made to correctly drain surface water. For positive drainage, it is recommended that lawn surfaces slope at 2 percent or 2 feet fall in every 100 horizontal feet (Figure 11—5). A planting bed that is steeper than this is susceptible […]

It considers how the overall space is formed and develops ideas for vertical and overhead planes of enclosure. An essential point to realize about form composition is that it is only the begin­ning step of preliminary design and by itself does not create a complete residential site design. When completed, form composition provides the basic […]

The third alternative, Figure 10—81, combines a modified diagonal theme with a curvilinear theme.

The second alternative is a combination of a rectangular theme and an arc and tangent theme (Figure 10—80). […]

In relating the new design forms to the functional diagram, the designer does not literally trace the diagram’s bubbles. For instance, the distance X between lines A and B has been repeated away from the house to establish the location of lines C and D. Relationship of Form Composition to Existing Structures With few exceptions, […]

This might lead to the use of an angular design theme, one that is usually quite different from most landscapes and can be quite visually active. The fourth and final example of architectural attention in the form composi­tion phase is illustrated in Figure 10-67. Architectural attention can be influential in selecting a design theme in […]

It has a rugged character and fits appropriately in areas that have irregular or abrupt Figure 10-57 An example of an angular design theme. Also, Figure 10-60 The design theme used in the front yard may be different from the one used in the backyard. topography with rock outcrops and boulders. The straight lines of […]

In terms of landform, sloping sites should be terraced in an arc and tangent theme owing to the structured character of many of the spaces. Figure 10-55 An example of an arc and tangent design theme. Rather, the designer must carefully decide which areas or lines of the composition require the use of arcs for […]

When it is suitable to emphasize a diagonal orientation, the diagonal theme offers a feasible compositional alternative for reinforcing and enhancing exist­ing site potentials. When diagonal emphasis is preferred without the strength of the pure diagonal theme, the modified diagonal theme offers a pleasant combination. When the lines of a pure diagonal theme connect to […]

The scale of the forms or areas within the composition also needs thought. Again, this is only a guideline and not a rule. When considering landform, a rectangular theme, like a circular theme, is best located on either level ground or on sloped ground where the different areas and forms of the design can be […]

However, it is strongly suggested that the words natural and freeform not be used to replace the term curvilinear. One guideline of the curvilinear theme is to have all intersecting curved lines meet each other at right angles (90 degrees; Figure 10-40). The flowing, sweeping lines of a curvilinear design also pro­vide a great deal […]
