Vladimir (Tom) Sitta is a czech landscape architect. After working in Czechoslovakia for 7 years, he moved to West Germany in 1979. He has made his permanent home in Australia since 1981.
He established Terragram, a firm of landscape architects, in 1986, and was a co-founder of Room 4.1.3 in 1998, with Richard Weller, a professor at the University of Western Australia. Their firms are known for their innovative - even iconoclastic - designs, often introducing extensive planting into urban projects - a form of landscape urbanism. Their landscaping schemes have won many design competitions and prizes. Built projects include the Garden of Australian Dreams at the National Museum of Australia in Canberra, and it also worked on Fusionpolis in Singapore (wikipedia).
