> To use an analogy, it is as if someone would sit down to design a building in the following way: first, they draw how they would like for the exterior to look. Then, they draw how they would like for the interior to look. They make basic measurements, to confirm that the interior does not exceed the exterior in terms of dimensions. They then suggest that the house is plausible, and send it off to the construction workers to build. For what it’s worth, this is how plenty of buildings are designed. Ignoring silly things like the inside not fitting in the outside, an architect may design the building and hand it off to a technical architect who works out how to make it stand up and has some back and forth with the architect modifying the design. At a later stage it goes to a structural engineer who will make sure that it really is likely to stand.
