A Legacy Built on Land, Trust & the Cosmos.
Ranjan Kumar Ojha
Founder & Chairman, Diarch Group
Building Bihar’s Future
From humble beginnings in Bihar, Ranjan Kumar Ojha built Diarch Group into one of the state’s most respected conglomerates, spanning eleven business verticals. Diarch Real Estate is the embodiment of his lifelong belief: that a home is not merely a structure, but a vessel for prosperity, harmony and generational legacy.
Under his stewardship, every Diarch project marries modern luxury with ancient Vastu wisdom — delivering homes that are as aspirational as they are auspicious, and always registered, transparent, and built to last.
“We build legacies aligned with the cosmos and the land of Bihar.”
