I disagree. I'd say there is a pretty direct route. The kid is trying to construct a building. They face great many object-level challenges: what materials to use, where to get them, how to connect them, how to make the structure stable, how to reduce work, etc. Behind each challenge is a field of study for the kid to dabble in, in order to overcome the problem.
"Real" architecture and civil engineering, as done by adult professionals, deals with exact same challenges (and then some more). The work is more complex, you need to explore relevant fields of study much deeper (and professional education gives you just that, in a structured way), but it's fundamentally the same thing, just in hard mode.
