In an inactive part of Turkovounia, which creates an extensive plateau, a powerful prism is placed, which functions as a gallery and a multi-purpose space for various activities, following an elongated rectangular shape that breaks at its end and turns towards the city. Free on all sides to create densification cores in the outdoor space is constructed by a repeated cell of a simple 10x10 m frame system. On the floor of the system, longitudinally detachable, movable and rotatable overlay elements are developed which provide possibilities for multiple versions and scenarios, depending on the actions of the participants. Indicatively, experimental stage, market, exhibitions and education are proposed in a freedom of movement and in conditions of play with the architecture and space itself.
