"They're based off of a form of housing where I'm from, called Apartments. Since most Thestrals can fly, the idea is to expand vertically, granting them a larger, busier district without requiring expansion of the wall, or shifting them outside. Once the Thestral voice is stronger in Canterlot, we can seek out a project of a larger scale, like constructing a new wall segment for a new district." Arnon explains, pointing to the blueprints.
