In 1974, Matta-Clark cut a suburban family house scheduled for demolition; action called "Splitting", a radical dissection from the house's foundation to the roof throughout the whole body of the house, creating a new and radical architectural state that anticipated his future interventions. Then came "Conical Intersect" and "Day's End". His works describe a permanent disagreement with architectural functionalism and modern principles of architecture and put forward an endless series of questions about architecture and the sense of space, where the value of space lies not on its functionality but on its metaphorical possibilities.
