The current Casey Station headquarters (the "Red Shed") was built in the late 1980s as part of the Australian Government's Antarctic Re-building Program. It was prefabricated in Hobart, Tasmania, by Hobart construction firm Contas Pty Ltd; trial-erected on the wharf at Hobart; then dismantled, packaged and shipped to Antarctica. Erected at Casey by tradespeople employed as workers on the normal summer expedition crews, it incorporates innovative design features to prevent the transfer of heat through the structure. The "Shed" is conspicuously located near the top of the hill on which the old radio masts stood. It is probably the largest single structure on Antarctica and was first occupied in 1988. The station has two other sheds, the green shed for storing food and the yellow shed for brewing. Homebrew beer is served at the station's bar, "Splinters".
