Dhiru was born in Bombay, India, and moved to Washington, D.C., in 1972 to study architecture. During his forty-nine years in Washington, D.C. he has taught, practiced, and strived to place traditional architecture and urbanism principles in the public eye. Since its formation in 1993, Dhiru has been a charter member of the Congress for the New Urbanism (CNU) and served as Task Force Chair and Board Member from 1997 to 2013.  Dhiru’s professional work has been recognized by the AIA, ISOCARP, and eight CNU Charter Awards. 

In 2022, he was elected Board Chair of the CNU DC Chapter and the chapter he co-founded in 2005.  In 2016 he was elected to be Vice President of Membership and Treasurer for the International Society of City and Regional Planners (ISOCARP).  In 2015 he was appointed to the inaugural CNU College of Fellows and received the International Society of City and Regional Planners’ Lifetime Achievement Award.  He is the recipient of the 2011 Seaside Prize, an award given for significant contributions to the quality and character of communities.  In 2001 he was a Knight Foundation Community Builder Fellow.

Dhiru is the author of The Language of Towns and Cities: A Visual Dictionary, published by Rizzoli in 2010, and was co-editor of Leon Krier: The Architecture of Community, published by Island Press in 2009.  Since its genesis, Thadani has documented the history and influence of Seaside, Florida, the first new urbanism project.  He has authored two volumes of the town. Visions of Seaside: Foundations / Evolution / Imagination / Built & Unbuilt Architecture was published by Rizzoli in September 2013, and Reflections on Seaside: Muses, Ideas, Influences, and New & Future Projects, was published by Rizzoli in April 2021.  In 2022, Dhiru published Washington  Drawings Abe to Zoo, a book of his drawings on the city.

Dhiru is currently researching and documenting 100+ American towns across all 50 states.  The graphic research typologically classifies the towns and follows their reason for establishment, historical growth, street pattern, topography, density, transportation network and accessibility, and economic drivers.

Since 2013, Dhiru has been working on regeneration efforts for the neglected and disinvested neighborhoods within Atlanta’s Westside.  He was initially retained to develop a master plan for the 66-acre campus of Morehouse College.  Understanding that the mission of the College could not be achieved without a safe and thriving neighborhood context, research was undertaken in surrounding areas.  Enlisting funds from Atlanta’s commercial and philanthropic groups, the scope expanded to cover 1,700 acres of blighted historic urban fabric less than one mile from downtown. 

In 2021, Thadani’s team was selected to update the master plan for Spelman College, the first private institution to educate women of color.  Founded in 1881, the college is a global leader in educating women of African descent. It is located within the Westside and is part of the Atlanta University Center academic consortium in Atlanta.

Other significant projects include a new city in China for a million inhabitants, several new high-density urban neighborhoods in India, and continued work at Seaside improving the public realm and the addition of buildings to improve the quality of life for residents and visitors.
