use "clean" design lines, with focus on hard landscaping materials like stone, hardwood, rendered walls. Planting style is bold but simple with the use of drifts of one or two plants that repeat throughout the design. Grasses are a very popular choice for this style of design. Garden lighting plays an integral role in modern garden design. Subtle lighting effects can be achieved with the use of carefully placed low voltage LED lights incorporated into paving and walls. With the combination of increasing demand for more efficient lighting, increasing availability of sustainable designs, light pollution considerations, and aesthetic and safety concerns, the methods and equipment of outdoor illumination have been evolving. The increasing use of LEDs, solar power, low voltage fixtures, energy efficient lamps, and energy-saving lighting design are examples of innovation in the field. Residential gardens A residential or private domestic garden such as the front garden or back garden is the most common form of garden. The front garden may be a formal and semi-public space and so subject to the constraints of convention and local laws. While typically found in the yard of the residence, a garden may also be established on a roof, in an atrium or courtyard, on a balcony, in windowboxes, or on a patio. Residential gardens are typically designed at human scale, as they are most often intended for private use. However, the garden of a great house or a large estate may be larger than a public park, and may contain specialized gardens (such as those for exhibiting one particular type of plant) and eyecatchers. Some early residential gardens include the Donnell Garden in Sonoma, California. The garden was designed by landscape architect, Thomas Church, with Lawrence Halprin and architect, George T. Rockrise, which was completed in 1948. The garden is currently regarded as a modernist icon and has been applauded for its well maintained garden of its time. The garden was recognized for its unique and organic forms that represented a modern style of California. The garden is on top of a hillside overlooking the northern area of San Francisco Bay. East Asian gardens Japanese and Korean gardens, originally influenced by Chinese gardens, can be found at private homes, in neighbourhood or city parks, and at historical landmarks such as Buddhist temples. Some of the Japanese gardens most famous in the Western world and Japan are Japanese gardens in the karesansui
