The Chinese architects called MAD gathered a bunch of fellow glass-steel-and-concrete artists to design the city center of Huaxi, in Guiyang, China. The goal was maximum eco-friendliness; the end product was a kinkily see-through skyline.
I'm not going to say I don't love the look of these proposed buildings—they are a noble attempt to put environmental relevance and soulfulness in front of sheer density and speed of construction—but damn if they don't appear to be freakishly devoid of privacy.
The building that MAD itself designed barely has so few enclosures, they must be planning to install bathrooms in the elevators. You can see it in the foreground above, and in the gallery below, along with three equally transparent concepts from BIG (which looks like a Wii), Emergent (which looks like it was designed by the Master Control Program) and Rojkind Architects (which looks like it was drawn by a Parkinson's sufferer).
You only start seeing some semblance of privacy when you get to this would-be Podling village by Serie:
There are 11 buildings total, all with seductively nouveau designs, some even fit for people who are modest, mecha fat and/or coyote ugly. To get a better sense of how they harmoniously fit together, hit the links. [MAD via designboom and Dezeen]
