Charleston-Style Piazza This porch is filled with comfy wicker furniture in traditional Charleston green, recognizable by its almost black color. Materials, such as wicker-looking resin for the frames and outdoor fabric for the cushions keep the space low maintenance. A few luxuries, such as pillows and throws can be quickly pulled inside when the weather turns bad. Iron-base tables with honed marble tops are the perfect sidekicks because they combine simple lines with elegant materials.
