A concert hall is a place for music. I wanted to preserve, to protect the classical music from extinction in my building. This is also a place for people to revitalise themselves, to regenerate and fly away from the everyday life. The roof of the building is like a big wing which protects the music and in the same time the wing is a symbol of freedom. The form of the roof is inspired by the origami tradition and the paper crane which is probably the most popular origami shape. The crane is a symbol of freedom, renewal and rejuvenation of the body and the spirit. Throughout all of Aisa, the crane has been a symbol of happiness and eternal youth. In the Greek mythology the crane was usually considered to be a bird of Apollo (the god of light, truth, music, poetry). He was also a healer and god-protector from evil. The points that I used to construct the roof of the building come from the constellation Grus (the crane).
