> Building components that are small enough to fit in highway lanes, on the other hand, are manufactured in centrally-located, capital-intensive factories and shipped to their final destinations, just like cars or electronics. Think: boilers, doors, windows, air handlers, etc. The elaborate on your idea, there are a couple startups that do work in "real estate" if you can even call it that, they ship ready-made prefab aimed at people looking for separate mancave/home office from the actual home.[1] Those are things you can ship in highways and load in with a crane. But that's about it. These startups had their boom during COVID but you don't hear much about them now.
