Construction on the new Sydney Fish Market from 3XN has topped out in Australia. The 700,000-square-foot building will become the largest fish market and have the largest glulam roof structure in the southern hemisphere once completed. Its PV-paneled roof is calibrated to withstand high wind loads while meeting the spatial demands required by the marketplace, is held in place by 594 beams, and is capable of harvesting rainwater throughout the year.The project offers a worthy follow-up to the Danish firm's award-winning work on theupcycled Quay Quarter Tower in Sydney. They are working locally with localarchitectsBVN, GXN Innovation, and the landscape architects Aspect Studios.
