Collision House is a 1981 work by artist and architect Vito Acconci which explicitly combines two of his main interests and activities. The departing point is the presence of two pure volumes, geometrically well defined as triangular prisms and materialized by two structures in corrugated aluminum. One volume stands on its base and the other on one side.
The central part of each one slides on tracks and one acts like a wedge toward the other. The collision generates two architectural structures out of the two volumes, revealing small windows and a roof, typical elements of the archetypal house. The mechanism is activated by the viewer, who can ride a bike located within the wedge making one volume move toward the other and the central volume of the second structure slide away. Two small doors are revealed by the sliding of the central part of the second volume.
