The world's first INFLATABLE concert hall arrives in Japan | smart cities |
British sculptor Anish Kapoor and Japanese architect Arata Isozaki created the Ark Nova structure which, when fully inflated, has room for about 500 guests

The unusual project is a balloon made of a coated polyester material, erected at a park in the town of Matsushima.

The structure, which organisers say is a world's first, measures about 18m and 35m wide when fully inflated with room for about 500 guests.
