Buchfelde is now a suburb of Gawler, South Australia, on the northern outskirts of Adelaide in South Australia. A property in the area was settled in 1848 by Dr. Richard von Schomburgk and his brother Otto, and is named after their financial benefactor Leopold von Buch who helped them flee Germany. The name was changed from Buchfelde to Loos in 1918 after a town in France which was the site of a battle in 1915. This was to remove a "name of enemy origin".
The modern boundaries of the suburb were set in June 2011 after the construction of the Northern Expressway. They are the Gawler River on the south, Northern Expressway on the west and north, and Gawler Bypass Road on the east, with the Two Wells Road through the middle. It contains the northern end of the Stuart O'Grady Bikeway which runs adjacent to the Northern Expressway, and the Gawler trotting track.
