Urban design
In 1990, Patel joined his father's practice in Ahmedabad. One of his first building design projects, a campus for The Entrepreneurship Development Institute, Ahmedabad, won the Aga Khan Award for Architecture in 1992. Over the years he has built up a significant body of work ranging from single family homes, to institutions, industrial buildings and urban redevelopment projects. Urban design projects, like the Kankaria Lake Development and the Sabarmati Riverfront, are the first of their kind in the country.
