The plan form and profile of the hall were determined by its principal use - as a baseball arena. The asymmetric dome is supported by a lightly tilted reinforced concrete ring raised on columns. One has the impression of a surprisingly light roof structure that seems almost to hover above the ground. As a result, it was possible to integrate the hall into its surroundings far more easily than other structures of this size. This sense of lightness is enhanced by the form of the load-bearing construction and by the translucent Teflon roof covering.
