What profession focuses on designing structures such as homes and commercial buildings?

The profession that primarily focuses on designing structures, including homes and commercial buildings, is architecture. Architects are responsible for the aesthetic, functional, and safety aspects of building design. They create detailed blueprints and plans that guide the construction process, ensuring that the structures not only meet client specifications but also comply with building codes and regulations. Architecture involves both artistry and technical knowledge, encompassing elements such as spatial design, materials, and environmental considerations.

Urban planning and interior design, while related, serve different purposes. Urban planning deals with the larger scale of land use, community development, and the organization of cities and regions. Interior design, on the other hand, focuses on the interior spaces of buildings, concentrating on aesthetics, functionality, and user experience within those environments. Engineering, while essential in the overall construction process, primarily focuses on the technical aspects, such as structural integrity and systems design, rather than the creative process of designing a building itself. Thus, architecture is the correct profession that encompasses the design of structures.
