This article raises the question of which design concepts can be brought into play and which architectonic principles, social interventions and modes of interaction can enhance the design of a genuine experience?

It is based on the analyses of a critical case, Roskilde Festival 2008 - 2011. The festival brands itself on the specific atmosphere: ’The orange feeling’, which is a very abstract term that wrap in the whole festival. The paper focuses on this term, and on important elements, which constitute the environment and the conditions for the constructed situation, where this special ‘Orange’ atmosphere actually will occur.
The main approaches to the analysis of the festival are the social and cultural organisation of the performances, the parties and the every day life of this temporal city - this also include the overall concepts and ideas behind the festival and how this is supported by the architectural scenography in the physical layout of the festival area.

The article provides general conclusions on concepts of social constructions of space, interaction and performance. It concludes that the culture of laughter is the atmospheric glue that keeps Roskilde Festival together and it is the culture of laughter that creates the basis for ‘the Orange Feeling’.
