One question that wasn't asked. What about when this fad has run its course? What happens when those that jump on the band wagon early and wholeheartedly adopt the idea of these communal areas, to include the upkeep, the gardening and their own little social experiment get tired of it?
Will there be another wave of people that are just as willing and able to continue these microcosms of society or will they be relegated to "project" housing?

Edward Bernays would disagree that "there is no magic wand to remove ingrained opinion."
We will buy anything we are told to buy.

The concept is intriguing, but it makes the assumption that everyone lives by themselves. How do couples or families coexist in these structures? The unattached young urban professional might be prevalent in certain urban areas but is by no means the norm in our or any society.

Oh Boy. Looks like they are making more room to bring people into the cities. This is right on target with Agenda 21.

see the link if you don't know what Agenda 21 is...

Eventually, the governments of the world will realize that in order for the world to support an ever-increasing population, people must become smaller. At that point, size restrictions on the populace will make these habitats an excellent place to be for multiple families. Exercise and energy generation can be provided by a large wire wheel in the common area.
It woud also be an excellent place to stash Grandma....

Many cities have accepted Axillary Dwelling Units, check your local building department for ADU's. The property owner can build a ADU in code approved areas. There was a day we called these mother-in-law apartments. Some property owners are moving into the smaller dwelling and renting out the larger home. This is also a way of bringing low income people into nicer, safer neighborhoods.

High density population centers are a health hazard. Epidemics spread like wildfire; the emotional stress of the lack of personal space degrades the immune system, creating vulnerability to health problems; violent behavior escalates; fires or chemical incidents kill in high numbers. Tell me again why we should promote this kind of living?
Distributed living styles, aided by today's enhanced electronic communications, can reduce or eliminate the problems listed above. Remote work environments can eliminate the commuter problems. Distributed power systems make us less vulnerable to widespread power outages. Efficiency can be achieved in more than one way.

@ Rt1583 there is no "when this has run it's course. This is UN Agenda 21, and like it or not they intend to make this as permanent as possible.
Unfortunately, in every generic socialogical experiment, cramming mammals to closely produces violence....Just about every High School has demonstrated this with lab rats, generally social, over crowd them and watch out.
@ KMH, how does that Kool-Aid taste?
I wouldn't live in a house that is the size of an average bedroom...and neither would most Americans. Heck, our holday decorations take up more space than this..not to mention camping gear, or fishing or Model airplanes ..or..or... these are Soros' idea of storage units for his "masses.

One might want to stack containers into interesting shapes. They have an ability to withstand earthquakes and fires also.

You might as well live in a Motor Home. I have, and loved it, same space and you can take off and see the sites. Even travel trailers have as much or more space. I know no one wants trailer parks in their backyard but they could be designed just as nice and much more affordable.
