An architect is a person who plans, designs, and oversees the construction of buildings. To practice architecture means to provide services in connection with the design and construction of buildings and the space within the site surrounding the buildings, that have as their principal purpose human occupancy or use.
Professionally, an architect's decisions affect public safety, and thus an architect must undergo specialized training consisting of advanced education and a practicum (or internship) for practical experience to earn a license to practice architecture. Practical, technical, and academic requirements for becoming an architect vary by jurisdiction.
The terms architect and architecture are also used in the disciplines of landscape architecture, naval architecture and often information technology (for example a network architect or software architect). In most jurisdictions, the professional and commercial uses of the terms "architect" and "landscape architect" are legally protected.
