What if, someday, we decided that the usefulness of our planet had run its course, and humans needed to scour space to find somewhere new to live? But instead of finding a potentially habitable Earth-like exoplanet light years away, we'd build our own artificial world right in the Solar System.

What kind of technology would we need to manufacture a new planet? Where would we find enough raw materials for our future world?
