Petroleum trailer tank rooms

I am not sure if this captures your imagination as much as it does for me. Think this will be as fun as this, as long as you don't roll off the edge of the pipe.

Designed by Lot-ek, the private areas within this apartment is contained by a petroleum trailer tank. The tank is cut in two sections. One of the two sections is suspended horizontally over the living room and contains two sleeping pods. The second section is placed vertically from floor to ceiling and contains two bathrooms stacked on top of each other.
