The German philosopher Martin Heidegger’s seminal essay “Building, Dwelling, Thinking”, published in 1954, is one of the texts which has had most influence on architectural thinking in the second half of 20^th and early 21^st century. What much of modern and postmodern architectural thinking extracts from Heidegger’s text and revolves around is the understanding of building and dwelling as more or less abstract forms of being without taking into account the people inhabiting space. In these traditions little has been said about what the Danish architect Jørn Utzon adds to the term “being” and announces as the most important aspect of architecture: Well-being understood as human well-being. The present paper means to re-interpret Heidegger’s text critically in order to rethink dwelling and building within an architectural context, presenting Jørn Utzon’s work and thinking as a lifelong search for the architecture of well-being.
