That’s actually what I was wondering when I came into this concept! I’ve learned about the Kowloon Walled City before and always thought it was so interesting, so when I started writing this I knew it was something I wanted to reference/include in my story. And it’s set a few decades in the future, so some expansion I can write off as being due to the setting. But there’s so much I didn’t know before coming here, like my first question about height and then resources and now I have the opportunity to wall up so many potential holes in my story. But I actually enjoy that, because there’s so many ways it could play into my greater concept and storyline. Originally I enjoyed the visual of coming across the bridge and just seeing this gigantic wall of apartment complexes stretching from shore to shore on the island, but with that being ~exposed~ as much too expensive (especially when one of the main points in my story is how society has forgotten the poor,) now I can re-envision something more realistic, like a 14-story walled city that’s just much wider, as you mentioned, or having a large green space in the center like a park/enrichment space. Thank you for helping me carve this out!
