They also outline in detail the methods of construction and draw up a list of necessary materials. Although many landscape architects supervise the installation of their design, some are involved in the construction of the site. However, this usually is done by the developer or contractor. Some landscape architects work on a wide variety of projects. Others specialize in a particular area, such as residential development, historic landscape restoration, waterfront improvement projects, parks and playgrounds, or shopping centers.
Some landscape architects teach at the college or university level.
Although most landscape architects do at least some residential work, relatively few limit their practice to landscape design for individual homeowners because most residential landscape design projects are too small to provide suitable income compared with larger commercial or multiunit residential projects. Some nurseries offer residential landscape design services, but these services often are performed by lesser qualified landscape designers or others with training and experience in related areas. Landscape architects who work for government agencies do similar work at national parks, government buildings, and other government-owned facilities. In addition, they may prepare environmental impact statements and studies on environmental issues such as public land-use planning. A landscape architect prepares final working drawings after a design is approved.
