Lord Rogers, who among other buildings designed London's Millennium Dome, the Pompidou Centre in Paris, and the iconic Lloyd's of London, "passed away quietly" on Saturday evening, international PR specialist Matthew Freud told the Press Association.
As well as grand statement constructions, Lord Rogers also designed sought-after, sustainable office buildings around the world, including the distinctive 'suspender building' with its distinctive red crosses at Chifley Square in Sydney.
Under the auspices of his firm, Rogers Stirk Harbour, he was also behind the International Towers development at Sydney's Barangaroo.
"The key word is community," Lord Rogers told the International Towers' official website of that development.
"What we've tried to do here is break down the idea of compartmentalisation and isolation, and create a genuine community that connects with the environment."
Richard Rogers was born in 1933 to an Anglo-Italian family in Florence, Italy, and at a young age moved to England, where he later trained at the Architectural Association School of Architecture in London before graduating with a master's from Yale University in the US.
His designs, which also include the Senedd government building in Cardiff and Strasbourg's European Court of Human Rights, won critical acclaim with the Royal Gold Medal and the Pritzker Prize, widely regarded as one of the world's premier architecture awards.
The jury when awarding him the Pritzker in 2007 praised him for having "revolutionised museums, transforming what had once been elite monuments into popular places of social and cultural exchange, woven into the heart of the city".
He received the Freedom of the City of London at Guildhall Art Gallery in 2014 in recognition of his contribution to architecture and urbanism.
He is survived by his wife Lady Ruth, sons Ab, Ben, Roo and Zad, his brother Peter and 13 grandchildren.
