Well, perhaps a solution similar to what we do in Enbarr would work.

[Edelgard has her thoughts, at least, and it'd been a long needed solution at home. So, why not attempt something here.]

We instituted public housing a number of years ago, to keep people within the protective walls of the city. Enbarr isn't often attacked, not like Aefenglom, but it is a fortress city.

That public housing, similar to apartments or barracks, is built upwards. That would keep people within the Bright Wall, at least.
