INNER SPACE - introducing a 'flying petals concept'. In a search of a cozy, noble intimacy with small balcony spaces of approx. 150 seats; these petals, more merged in the lower stage level and more diffused in the upper balconies levels, with the emphasized effect of free floating, surfaces are physically detached of the balconies, free of its visual weight. The overall layout of reflecting surfaces has been developed to achieve the required ‘early acoustic efficiency’. Preliminary calculations on the conceptual 3D model suggest 25% EAE. This is achieved through the stage surrounds, the over-stage reflectors, the floating petal reflectors and the cliffs. To provide the required density of lateral reflections to all audience areas, the seating has been subdivided into a series of smaller areas. The boundaries of these areas comprise the predominantly lateral reflecting surfaces which individually or together achieve whole stage imaging for the seats they serve. This approach contributes significantly to improving the acoustic and visual intimacy for the audience.
OUTER SPACE - Rather than forming a lonely “object”, one should form a variously connected “space(s)”, one complex; therefore a vegetative rooftop covers the outline of the area and defines it as one system. In addition to the continuity & variety of the global “symphonic” spatial event the rooftop was created as a garden, a playground, an upper semi-public foyer, actually, the event of ground floor piazza is diffused also in the upper space giving it a new dimension of the social aspect of the park, a promenade, a relaxing space.
