Depends. I don't know which glass they are using but I did some back of the napkin calculations for a project I was dreaming of that had some "glass" and it would cost $8-9k just for the glass alone. It was not that much glass. Probably a bit more than this cube. That's if you are looking for some premium glass that won't shutter into a thousand pieces and hurt you. Same for steel, aluminum, high quality wood, etc... So yes, it can be very expensive. A cheap wooden dwelling can be pretty cheap though.
