The topic of the thesis is the relation between the concepts house and home in Ibsen s drama. I believe that the relationship between house and home is common to his oeuvre in general and not specific to some plays. I study the relation between the concepts house and home in John Gabriel Borkman based on a performance I saw in Teater Ibsen in Skien in September 2012. In the first chapter, I support my claim that Ibsen's works have an existential dimension on the house/home concepts by drawing on Anthony Vidler (1992), Mark Sandberg (2001, 2007 and 2015) as well as Mark Wigley (1993). In the second chapter I explain by Heidegger why Anders T. Andersen was provoked by Ostermeier s version of John Gabriel Borkman. Andersen found that Ostermeier had no sub-text – or in other words – no existential dimension. Although originally a Freudian concept I apply Heidegger's concept of the uncanny (das Unheimliche) in a metaphysical perspective drawing on Anette Storli Andersen s master thesis based on Robert Wilson s Peer Gynt. In a third and last part this thesis examines the main changes in modernity and late modernity on the house and home concept based on Richard Sennett, Anthony Giddens and Hannah Arendt. One of the main changes affecting the construction of genres, I grew an interest for the problematic of manhood in John Gabriel Borkman in a sub-part based on Fredrik Engelstad (1994) and Chengzou He (2008).
