In 1993 Burr was invited to participate in several large scale exhibitions in Europe, including Sonsbeek '93, curated by Valerie Smith, Unite in Firminy, France, curated by Yves Aupetaillot, and Kontext Kunst, curated by Peter Weibel.
In the late 1990s Burr embarked on a body of work that remains ongoing; derived from the language and forms of both Tony Smith's sculptures, on the one hand, and closed architectural spaces such as bars, cages and boxes.
