They produce detailed plans of the site, including written reports, sketches, models, photographs, land-use studies, and cost estimates, and submit them for approval by the client and by regulatory agencies. If the plans are approved, landscape architects prepare working drawings showing all existing and proposed features. 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 landscape 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 in colleges or universities. 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.
