@KHLVH1345 If it's outside of the boundaries of the lot I don't think you'll be able to achieve what you're looking for. There are cheats and mods depending on your platform (I'm on console) that allow some modifications to hidden worlds for example that I'm aware exist but I've not used them. But editing the general world around your lot when I've looked, I found the answer was no.
I edit a lot of public spaces but I'd have liked to do more outside of lots too. Maybe we'll see it from Project Rene in the next installment of the Sims franchise. I hope so.
