Landscape Architecture is a profession concerned with both the built and natural environments. Landscape architects have a firm commitment to improve the quality of both environments through careful planning and design. In the past, landscape architects were known as designers of gardens and parks. Today landscape architects are continuing this tradition, but have also expanded the field to include planning, design and management of several aspects of the physical environment. They are also specialists in site planning, which require the expertise of an architect labor management, cost and quality control, advanced methods of construction, selection of building and structural systems, building science, specialized services and computer applications. Special emphasis is placed on practical aspects through various case studies, which form integral part of the programme.
