What if the reason City 17 doesn’t make sense sometimes is because the cities in Half-Life aren’t real cities the Combine use, but instead are streets and blocks that are still relatively intact after the war and they uplift them, similar to how they abducted the building inside the Vault, and fit the streets together? Then probably the first decade after the 7 hour war is just reconstruction and implementation of the newly created cities, where the smooth things out at the edges of each reconstructed piece? It would also kind of explain why most buildings look decent on the outside despite having to go through an alien invasion. No evidence for any of this, just my opinion on the vague lore.
Could explain why there's a fucking warehouse connected to an apartment building in the uprising chapters.
