For 17 years Trevor and Francoise Sullivan have lived with their two kids and numerous animals in an open sided shed on 33 bushy acres at Lake Bennett south of Darwin. With money tight they were sustained by thoughts of the beautiful home they’d one day enjoy – so they both nutted out a unique design. A cyclone proof, tropical tree house that is windowless and based on the shape of a 50 cent piece. With little or no funds, Trevor (a wood carver) is building it all himself (including furniture) with the help of generous mates. The going is slow but one of the first things finished is the magnificent central staircase, carved from a fallen Paperbark Tree. Will they get the roof on before the wet season? That is the question.
