I never thought I would catch myself typing the words ferro-cement organic. Being of a certain age I have vague memories of chicken wire and concrete disasters lurking in under house games rooms or pseudo hippy hang outs. The type of weekend DIY that seemed like a good idea at the time until the sheer scope of the job overwhelmed the home owner. I blame it on Antoni Gaudí, Frank Lloyd Wright and Antti Lovag. The Hollander House, built in the late 60s early 70s by architect David Hollander, is no weekend hodge podge. Now recognised as a icon of Australian organic architecture its current interior designer owner has listed the house for sale with Modern House.  Part Fred Flintstone, part scifi, all retrolicious you can read more of its history and design here. (Real estate listing also here while it lasts.)
