Ensaio 04 is a geometric study of a curved surface built through straight planes of poplar wood, resulting in a perspective deformation.

The exercice proposed by FAHR presents a scenic element related to the theater, which is also an exercise of scale since it relates the building with the public space, creating a temporary urban scenary. Besides, Ensaio 04 is a strange object due to the illusion that it creates to the human eye, and because of the relations of shadow / light, full /empty that change during the day.

Essay 04 takes part in a set of geometric experiments developed by FAHR and was developed from a challenge of the Municipality of Póvoa de Varzim for the celebration of the 3rd anniversary of the reopening of the Garrett Cinema-Theater.
