What Is an Architect?

An architect is a trained professional who organises, designs, and oversees construction projects. Turning ideas into safe and usable structures is the job of an architect in India. They participate at all levels of the construction process, from concept to completion.

  • Houses and villas

  • Offices and companies
  • Schools and universities
  • Hospitals and medical centres

Architects and interior designers differ mostly in what they focus on designing.
