The height of the finished sculptures varies between 10-19 meters (4 meters for "Baustelle Villa Schöningen", ca 3,5 m for "Berlin Chimney Project" and 2,3 m for "Fragment av # 10"). The "First Chimney" was destroyed in 1994. The "Third Chimney" was destroyed in 2007 and the "Second Chimney" at some point around 2012-2014. "Baustelle Villa Schöningen" and the two indoor chimneys were temporary projects and were destroyed in the same year they were built. The others are still standing.
