Historically, the phrase "going troppo" came into prominence in World WarII. It meant to be "heat affected", one went "off", a little mad in theheat of the tropics. This is the story of two architects who "wenttroppo", but in doing so, found another state. For them it meant becomingacclimatised, not going "off" at all, but understanding the place. "Goingtroppo" was revealing - even enlightening - and it would provide the basisfor a new practice of architecture in Australia's Northern Territory.
