He has degrees from Leibniz Universität Hannover and Aarhus School of Architecture and has taught at the University of applied science in Lübeck, Germany and DIS in Copenhagen. Between 2002 and 2016 Jansen designed and single-handedly built three award winning, experimental summerhouses; `langelinie´, `black & bright´ and `birkedal´ on the Danish Island of Møn. These three houses served as a laboratory where Jansen experimented with design, detail and materials and led to the launch of his practice, Jan Henrik Jansen Architects, in 2012. Today Jansen works internationally specialising in idiosyncratic and thoughtfully designed houses. He collaborates closely with Australian Architect Marshall Blecher on many of these projects.
