A person who designs buildings is called an architect. Architects are trained professionals who plan, design, and oversee the construction of a variety of structures, including residential homes, commercial buildings, and public spaces. They work to create functional, safe, and aesthetically pleasing designs while considering factors such as environmental impact, zoning regulations, and client needs. The process often involves creating blueprints, models, and detailed plans. Architects also collaborate with engineers and contractors to ensure the designs are feasible and executed correctly during the construction phase.
