A compilation of materials with which seventeen artists reflect on the gap between architecture as idea, architecture on paper, and its actual use in other words, the afterwards of construction. The project distinguishes four possible typologies of the afterwards: back, interior, around and demolition. These typologies of the afterwards would in this way come to compose a kind of heterotopia of architecture.
