‘I suspect it will come down to fees,’ he added.
The brief issued by the authorities of Praga Poludnie district of Warsaw called for the provision of a 12,000 m2 1,500-seat facility, an Olympic-size ice rink, and a health club with squash and tennis courts.
The roof of the ice rink in Studio Bednarski’s entry is suspended on steel tendons and made of highly insulated low-emission concrete planks and is designed to cope with the city’s fluctuations in temperature which range between –20°C and +32°C.
