The use of vertical elements and setbacks in the exterior design contributes to the Streamline Moderne aesthetic in several ways:
1. Sleek and Aerodynamic Appearance: The vertical elements, such as vertical fins or decorative towers, enhance the streamlined look of the building. These features create a sense of sleekness and aerodynamic flow, mimicking the smooth lines of transportation vehicles like airplanes, ships, and trains. The setbacks, which involve recessing or stepping back certain portions of the building, help create a sense of depth and perspective, further accentuating the dynamic and streamlined appearance.
2. Emphasis on Verticality: The vertical elements in Streamline Moderne designs emphasize a sense of height and verticality. This aesthetic choice is influenced by the era's fascination with the modern concept of skyscrapers and tall buildings. By employing vertical elements, the architecture embraces the vertical nature of the urban landscape and complements the emerging trends in city planning.
3. Visual Interest and Dynamic Composition: The use of vertical elements and setbacks in exterior design adds visual interest and dynamic composition to Streamline Moderne buildings. These elements break up the horizontal lines of the structure and create a sense of movement. The play of light and shadow on the vertical surfaces and various setbacks further enhances the overall visual appeal of the building.
4. Symbolic Representation: The vertical elements and setbacks can also hold symbolic meaning. The vertical fins or towers may represent progress, technological advancements, and aspirations for vertical development. Additionally, the setbacks in the design visually separate different functional areas of the building, showcasing their distinctiveness and function.
Overall, the use of vertical elements and setbacks in Streamline Moderne architecture helps create a visually striking and cohesive aesthetic that embodies the streamlined and futuristic ideals of the time.
