Duncan Stewart is an Irish architect, environmentalist and media personality known for his environmental activism and work on Raidió Teilifís Éireann (RTÉ).
In 1969-70, while still a student, Stewart led the six-month occupation of a row of seven large Georgian houses on Hume Street in Dublin, in protest at their planned demolition in favour of a new office block.
In 2003, he had a near-fatal accident while filming a documentary in Chernobyl.
In April 2014, he vowed to walk out of an interview on the Newstalk Breakfast Show unless he was given more time to speak on the topic of climate change. During the interview he claimed that climate change is not sufficiently covered by the Irish media.About the House
