Really cool house, but describing the cabinets as "bunch of wood, cut into fairly large pieces. Maybe a few screws and hinges" shows little understanding of what goes into building something like that.
It's hard to tell from the pics if the cabinets are made of sheet goods with veneer or solid boards glued into panels. But at the very least, the trees need to be grown, they need to be managed, they need to be felled, sent to processing for sheet goods, dried and milled for solid wood. Even then you've got to get everything cut to size and square, then build the cabinets with all the specific sizes, then finish them, transport to site and install everything and the trim.
It's two ends of the manufacturing scale. For transistors, you've got mass production at an impossibly difficult level of accuracy for a human and for cabinets you've got single production (at the install level) at very difficult level for a human.
But again, very, very cool house. I especially like the cat doors but not nearly half as much as I imagine the cat does.
