The concept : To make a new identity to an urban space / building means to develop the existing circumstances. to emphasize their main qualities.We propose a continous space for music and cultural events, variable, fluctuating, to give a chance to everybody to make its CHOICE (also our pseudonym for the competition) of the approach deisred, in the desired team, in a desired purpose, at time desired, in a large scale of convenient occasions.We propose a continous space from outside to inside, from top to bottom, from dark to light, from static to dynamic, from monumental to friendly, from hidden to exposed, from historicity to contemporaneousness.We use in that purpose a lapidary, minimalist language, inspired by the calm, classical urban and architectural surroundings and by the mystic minimalism that characterize the works of Arvo Part (the name of the hall-former church which is the subject of the competition, also the name of a famous estonian musician). A reversible relation both in the urban and in the architectural space, like "mirror in mirror", summarizes our approach.
