"Well, I think I'd rather be doing a straight line," Mr Cook said jokingly.
"But I think it's pretty cool, I enjoyed working with Frederick [Hundertwasser] even though you needed patience. Things are not the norm with him, he has his own ethos of building - so not too many straight lines."
The $300,000 Te Kakano build kicked off in May and was expected to wind up in September. Hundertwasser Foundation representative Richard Smart said a "folly" construction was a requirement for every Hundertwasser building, to allow the local craftspeople a chance to master the techniques required.
"The proviso is that all the elements of the main build are worked into this. Then when this is finished the architects can come over from Germany ... They can look at this and say you've done this bit wrong, this bit right and so on."
Mr Smart said the workers involved needed to be able to work creatively. "Not everyone is receptive to this sort of work," he said. "Some people like to do what they know and that's it. You need people who are receptive to doing things in a different way and interested in doing something a bit more creative."
