and what about poop?

Having done a lot of camping in my time, this was the first thing I thought as well. If you haven't got somewhere to poop and somewhere to get rid of it, life is miserable. Believe me, burying it isn't fun.

Seems like one of those idealistic almost art project houses rather than something you could actually live in.

They say in the FAQ you'd have to add plumbing etc. to the cost. This was just a test build.

So its an art installation..

Unless someone has lived in one for months, it's purely magic unicorn poop.
