A photo we took in the Museum of Modern Art in New York in 2012 of this big 1:250 scale architectural model.  More pics of it are here.  According to the description:

‘Nature-City builds upon WORKac’s strength in ecological urbanism as the proposal questioned “What if we could live sustainably AND close to nature? ”Encouraged by team member Eric W. Sanderson, a Senior Conservation Ecologist at the Wildlife Conservation Society, WORKac incorporated publicly accessible nature, ecological infrastructure, sky gardens, urban farms and large swaths of natural habitats, from an oak savanna and wetlands to a Douglas Fir forest.

‘In Nature-City, your house generates power, cleans water, composts food or grows mushrooms. You can live, work, can food, rock-climb and walk to the movies all in the same day. You can live in a tower of houses, or on a hilly roof-top pond. In Nature-City your backyard is nature and you can afford it.’

When the Maypole company announced its massive subdivision for Waikanae with its intended 1,700 housing units at the end of 2014, we wondered if it had this sort of thing in mind.  But what has been built so far looks like a normal subdivision, perhaps a little more like Ferndale than Waikanae North (for example) — however, information it has made public so far is fairly vague and imprecise.
