Yeah, as a father to three... all I could think of when reading the article was "The bliss of ignorance a 20-something, single kid-less person has... if only I could live in a Dome with no restroom"!
Well, ahem, you may be aware that in some places in the world some families have plenty of kids and no restrooms in their houses. Actually there is quite a lot of them.
Restrooms is not the problem here, the problem is this focus on frameless structure. Why not just doing a tent, like in so many traditional cultures? It must be easier to build and may even be more pleasing to the eyes.
While I am well aware that ther are billions that live in lesser conditions than the hipster-dome under discussion, one of the points of the article was that there is "inefficiency" in the home rental/ownership paradigm; while this may be true - I do not see how this is solved by sacraficing something as crucial as a bathroom (or kitchen [I lived in my house during a kitchen remodel, and I cooked using my backpacking gear for 2 months, and that FARKING SUCKED])
So - Yeah - this would be a great fort, or cool guest room, I'd not want to actually live there.
Ever have to walk from your "room" to the bathroom when there is a monsoon-like storm outside which you must traverse (at 4am). No thanks
Then I had two kids =)
