Since 1998, OLDHAUS has been addicted to can technology. From 2008-2014 he studied design, with a focus on illustration, at the University of Applied Sciences Düsseldorf. In addition to numerous art events and exhibitions in Germany, his art has mainly been seen in Western Europe. 

Specializing in character design (figurative painting), art drove him all the way to Belarus, where he won a juried international contest as 1st place in the graffiti category. 

In 2019, OLDHAUS came into the light for the first time as curator and initiator when he and three other artists launched the cross-city, Home Street Home Urban Art Festival.

His last trip took him to the Queen's kingdom - he has already exhibited several times in London. In the metropolis, he has been represented by the Bickerton Grace Gallery since 2020. In addition to his large-scale graffiti, OLDHAUS also paints on canvases using mixed media, on which he likes to deal with problems of his synapse chaos.
